Understanding the Sane Exam: Core Definition and Purpose

The Sexual Assault Nurse Examiner (SANE) exam represents a specialized medical and forensic approach designed to address the complex needs of survivors of sexual violence. Unlike conventional medical evaluations, the SANE exam integrates clinical care with forensic evidence collection, ensuring both medical treatment and legal documentation occur in a single, trauma-informed setting. Its development reflects a paradigm shift in how society responds to sexual assault, prioritizing victim-centered care while upholding legal standards. This section explores the full form of SANE, its historical evolution, and the multifaceted objectives that distinguish it from other forensic examinations.

Definition and Full Form of SANE in Medical and Forensic Contexts

What Is A Sane Exam Explained Clearly And Concisely The acronym SANE stands for Sexual Assault Nurse Examiner, though it is sometimes expanded to Sexual Assault Forensic Examiner to reflect the broader role of healthcare professionals beyond nurses, including physician assistants and physicians. The term originated in the late 1970s in the United States, as part of efforts to improve the quality of evidence collection and medical care for survivors of sexual assault. Initially, these exams were conducted by general medical practitioners, often in environments that lacked sensitivity to the psychological and emotional needs of survivors. The emergence of SANE programs marked a critical advancement by introducing specially trained nurses with expertise in both forensic science and trauma-informed care. The SANE exam is a comprehensive assessment that includes:

  • Medical evaluation to identify and treat injuries, infections, or other health concerns.
  • Forensic documentation of physical evidence, such as injuries, trace evidence, or bodily fluids, for potential legal proceedings.
  • Psychosocial support to address the immediate and long-term emotional impacts of sexual violence.

    • Unlike traditional forensic examinations, which may focus solely on evidence collection, the SANE exam is holistic, addressing the survivor’s physical, emotional, and legal needs in an integrated manner.

    Historical Background and Evolution of SANE Programs

    The evolution of SANE programs is deeply intertwined with the feminist movement, legal reforms, and advancements in forensic science. Key milestones include:

  • 1970s–1980s: The women’s rights movement and survivor advocacy groups, such as Rape Crisis Centers, began pushing for better medical and legal responses to sexual assault. Early programs, such as those in Los Angeles and New York, trained nurses to conduct exams, recognizing the need for specialized expertise.
  • 1990s: The International Association of Forensic Nurses (IAFN), founded in 1992, standardized training and certification for SANE nurses. This period also saw the adoption of sexual assault response teams (SARTs), which included collaboration between law enforcement, medical professionals, and advocacy organizations.
  • 2000s–Present: Global expansion of SANE programs occurred, with countries like the UK, Australia, and Canada adopting similar models. The U.S. Department of Justice funded initiatives to increase SANE availability, particularly in underserved areas. Technological advancements, such as DNA analysis and digital evidence collection, further enhanced the forensic aspects of these exams.

    • A comparative analysis reveals that while rape kits (or sexual assault kits) focus primarily on evidence collection, SANE exams incorporate medical treatment, victim advocacy, and legal documentation into a single process. This distinction ensures that survivors receive immediate care while preserving evidence for potential prosecution.

    What Is A Sane Exam Explained Clearly And Concisely The SANE exam serves three primary objectives, each addressing a distinct but interconnected aspect of sexual assault response: SANE exams are designed to provide immediate medical attention while identifying potential injuries or health risks, such as:

  • Infections (e.g., sexually transmitted infections like HIV, chlamydia, or gonorrhea).
  • Physical trauma (e.g., lacerations, bruising, or internal injuries).
  • Pregnancy risk, including emergency contraception options.
  • Mental health assessment, screening for acute stress, PTSD, or depression.

    • Forensic documentation ensures evidence is collected and preserved according to chain-of-custody protocols, which may include:

  • Photographic evidence of injuries.
  • Swabbing for DNA from potential assailants.
  • Collection of clothing or trace evidence (e.g., hair, fibers).
  • Detailed medical history and exam notes for legal use.

    • Victim-centered care prioritizes the survivor’s dignity, autonomy, and emotional well-being, including:

  • Trauma-informed communication, avoiding re-traumatization during the exam.
  • Clear explanations of each step to reduce anxiety.
  • Access to counseling and support services, such as crisis hotlines or advocacy organizations.
  • Flexibility in timing, allowing survivors to proceed at their own pace.

    • Comparative Analysis: SANE Exams vs. Other Forensic Examinations

    While sexual assault kits (SAKs) and rape kits are often used interchangeably with SANE exams, they differ significantly in scope and approach. The following table highlights key distinctions:

    Feature SANE Exam Traditional Sexual Assault Kit (SAK)
    Primary Focus Medical treatment + forensic evidence collection + victim support Forensic evidence collection only
    Conducted By Specially trained nurses, physician assistants, or physicians (SANE-certified) Forensic nurses, evidence technicians, or general practitioners (varies by jurisdiction)
    Environment Trauma-informed, private, and supportive (e.g., SANE clinics, ERs with specialized training) Often conducted in police stations, hospitals, or forensic labs (may lack trauma sensitivity)
    Evidence Handling Integrated with medical care; includes immediate documentation and victim advocacy Evidence collected separately, sometimes days after the assault
    Legal Admissibility High due to standardized protocols and victim-centered approach Depends on collection procedures; backlogs may compromise chain of custody
    Victim Experience Reduces re-traumatization through compassionate care May feel impersonal or invasive without additional support

    Key Insight: The SANE exam’s integrated approach ensures that survivors receive both medical and emotional support while evidence is collected, whereas traditional SAKs may prioritize forensic goals over victim well-being.

    Timeline of Key Milestones in SANE Development and Adoption

    The global adoption of SANE protocols has been shaped by legislative reforms, medical advancements, and advocacy efforts. Below is a chronological timeline of pivotal developments:

    Who Conducts a SANE Exam: Roles, Qualifications, and Interdisciplinary Collaboration

    The Sexual Assault Nurse Examiner (SANE) exam is a specialized medical forensic process that requires precise expertise, emotional resilience, and a deep understanding of both medical and legal systems. Behind every SANE exam is a team of highly trained professionals whose roles extend beyond clinical practice to encompass advocacy, documentation, and trauma-informed care. The effectiveness of the exam hinges on the qualifications, training, and collaborative efforts of these professionals, who operate within a structured yet adaptable framework to ensure justice and healing for survivors. Understanding their responsibilities, the rigorous certification processes they undergo, and the challenges they face provides insight into the critical infrastructure supporting SANE programs.

    Key Professionals Involved in SANE Exams and Their Roles

    SANE exams are conducted by a multidisciplinary team, with Sexual Assault Nurse Examiners (SANEs) as the primary clinical professionals. Their roles are complemented by forensic nurses, physicians, social workers, law enforcement officers, legal advocates, and mental health specialists. Each member contributes specialized skills that align with the exam’s dual objectives: collecting forensic evidence while providing compassionate, survivor-centered care. Sexual Assault Nurse Examiners (SANEs) are registered nurses with advanced forensic training who perform the medical-legal examination. They collect evidence, assess injuries, administer emergency treatment, and provide referrals for follow-up care. SANEs often act as expert witnesses in court, translating complex medical findings into clear, legally admissible evidence. Their work requires a blend of clinical precision, forensic documentation, and advocacy. Forensic Nurse Examiners (FNE) share similarities with SANEs but may operate in broader forensic contexts, such as examining victims of abuse, violence, or neglect. While some FNEs specialize in sexual assault, their scope can include domestic violence, child abuse, or elder abuse cases. Their training ensures they can handle diverse forensic scenarios with the same rigor as SANEs. Physicians may also conduct SANE exams, particularly in settings where a SANE is unavailable. Emergency medicine physicians, obstetrician-gynecologists, or family practitioners with forensic training can perform these exams, though their involvement is often limited by time constraints and less specialized training compared to SANEs. Social Workers and Advocates provide emotional support, connect survivors with resources, and ensure their rights are upheld throughout the process. They often accompany survivors to the exam, offer crisis intervention, and assist with long-term support services, such as counseling or legal aid. Law Enforcement Officers coordinate with medical teams to ensure evidence is collected and documented according to legal standards. Their role includes obtaining consent for evidence collection, transporting survivors to the exam, and liaising with prosecutors. Mental Health Professionals, such as psychologists or counselors, assess trauma symptoms and provide immediate or ongoing therapeutic support. Their involvement is crucial for addressing the psychological impact of sexual assault and preventing long-term harm.

    Certification Process for Becoming a Sexual Assault Nurse Examiner (SANE)

    Becoming a SANE nurse is a multi-step process that demands extensive education, clinical experience, and specialized training. The certification is offered by two primary organizations in the U.S.: the International Association of Forensic Nurses (IAFN) and the American Nurses Credentialing Center (ANCC). Below is a step-by-step breakdown of the certification requirements: 1. Educational Prerequisites Applicants must hold an active, unencumbered Registered Nurse (RN) license and possess a minimum of two years of nursing experience in a relevant clinical setting, such as emergency departments, labor and delivery, or pediatric units. Some programs recommend or require a bachelor’s degree in nursing (BSN), though it is not always mandatory for certification. 2. Forensic Nursing Education Candidates must complete a forensic nursing program accredited by the IAFN or ANCC. These programs typically range from 40 to 100 hours and cover topics such as:

  • Forensic science principles
  • Evidence collection and chain of custody
  • Trauma-informed care and victim advocacy
  • Legal aspects of sexual assault examination
  • Documentation and courtroom testimony

    • Popular programs include:

  • SANE Certification Programs offered by universities or forensic nursing associations.
  • Online courses (e.g., through the IAFN’s Forensic Nursing Certification Board).
  • Workshops or conferences sponsored by organizations like RAINN (Rape, Abuse & Incest National Network) or local SANE programs.

    • 3. Clinical Hours Applicants must accumulate a minimum of 200 clinical hours in sexual assault examination under the supervision of a preceptor who is a certified SANE. These hours include:

  • Direct patient care (e.g., performing exams, collecting evidence).
  • Documentation and reporting (e.g., completing forensic reports).
  • Consultation with law enforcement and legal teams.

    • 4. Certification Examination The final step is passing a comprehensive certification exam administered by the IAFN or ANCC. The exam consists of:

  • Written component: 150 multiple-choice questions covering forensic nursing knowledge, legal principles, and clinical skills.
  • Practical component (for some certifications): Simulated scenarios to assess hands-on skills, such as evidence collection techniques.

    • Certifications are valid for five years, after which nurses must complete continuing education credits (typically 100 hours) to renew their status.

    Note: Some states or healthcare systems may have additional requirements, such as completing a state-specific forensic nursing course or obtaining malpractice insurance before practicing as a SANE.

      The SANE Exam Process: Step-by-Step Breakdown

      The Sexual Assault Nurse Examiner (SANE) exam is a meticulously structured process designed to provide comprehensive medical care, forensic evidence collection, and trauma-informed support to survivors of sexual assault. Unlike routine medical examinations, a SANE exam integrates clinical assessment with forensic documentation, ensuring findings are admissible in legal proceedings while prioritizing the survivor’s physical and emotional well-being. Each phase—from pre-examination intake to post-examination follow-up—follows standardized protocols to maintain accuracy, sensitivity, and professional integrity. Below is a detailed breakdown of the SANE exam process, emphasizing the interplay between medical, forensic, and advocacy components.

      Pre-Examination Phase: Intake and Initial Assessments

      The pre-examination phase sets the tone for the entire process, focusing on establishing trust, ensuring privacy, and addressing immediate medical or emotional needs. Survivors often arrive in a state of distress, making this phase critical for creating a safe environment. Victim intake procedures begin with a confidential interview conducted by a trained SANE nurse or advocate in a private, controlled setting. The survivor is provided with clear explanations of the exam process, their rights, and the option to decline any part of the examination. Privacy protocols include secure waiting areas, separate interview rooms, and strict adherence to confidentiality laws, such as the Health Insurance Portability and Accountability Act (HIPAA) in the U.S. or equivalent regulations in other jurisdictions. Initial assessments evaluate the survivor’s emotional stability, immediate medical needs, and legal considerations. The SANE nurse assesses for acute injuries, signs of intoxication, or medical conditions requiring urgent intervention (e.g., pregnancy, sexually transmitted infections, or physical trauma). A trauma-informed approach is employed, where language and actions avoid re-traumatization. For example, the nurse may use open-ended questions to allow the survivor to share their experience at their own pace, such as: > "I’m here to support you. Would you like to tell me what happened, or would you prefer to focus on your care first?" Documentation during this phase includes a medical history, timeline of events, and any prior medical or legal involvement. The survivor’s consent is obtained for all procedures, with special attention to capacity to consent, particularly if the survivor is underage or impaired. This phase also involves coordination with law enforcement (if requested) to ensure evidence collection aligns with legal timelines, though the survivor retains autonomy over whether to involve authorities.

      Physical Examination: Systematic Assessment and Evidence Collection

      The physical examination is conducted in a private, medically sterile environment and follows a head-to-toe protocol to ensure thoroughness while minimizing discomfort. The SANE nurse begins with a general assessment, including vital signs, height, weight, and any visible injuries (e.g., bruising, lacerations, or signs of struggle). The exam proceeds systematically, with the survivor fully clothed unless they choose to undress for specific assessments. Trauma-informed language is used throughout, such as: > "I’ll explain each step before we proceed. You can stop me at any time if something feels uncomfortable." Key areas assessed during the exam include:
    • Oral and pharyngeal regions: Swabs are collected from the mouth, throat, and cheeks for potential DNA evidence (e.g., saliva, semen). Alternative light sources (e.g., colposcopy or ultraviolet light) may be used to detect subtle injuries or semen fluorescence.
    • Genital and anal areas: A colposcope (a magnifying device with a camera) is often used to examine for trauma, foreign objects, or signs of assault. Swabs are taken from the vagina, anus, and perineum, and photographs are captured with the survivor’s consent. Tollens’ test (a chemical test for semen) may be performed if semen is visible.
    • Breasts and torso: Examined for injuries, bite marks, or other trauma. Photographic documentation follows the same consent-based protocol.
    • Extremities and back: Assessed for defensive wounds, bruising, or signs of restraint.
      • Alternative light sources (ALS) play a pivotal role in detecting injuries not visible under normal light. For instance, ultraviolet (UV) light can reveal semen, blood, or bite marks that fluoresce, while infrared light may highlight bruising that has faded. The SANE nurse uses these tools cautiously, explaining their purpose to the survivor: > "This light helps me see injuries that might not be visible otherwise. It’s completely safe and won’t hurt." Evidence collection is conducted using sterile, single-use tools to prevent contamination. Swabs are placed in sealed, tamper-evident containers, and photographs are labeled with chain-of-custody documentation, including the date, time, and nurse’s initials. The survivor is offered the opportunity to review and approve all documentation before it is finalized.

      Essential Tools and Equipment in a SANE Exam

      The SANE exam relies on specialized tools to ensure forensic accuracy and medical safety. Below is a checklist of essential equipment, categorized by function, along with their purposes:
      • Forensic Documentation Tools
        • Colposcope with Digital Camera: Magnifies and photographs genital, oral, or anal injuries with high resolution. Used to document trauma, foreign objects, or semen.
        • Alternative Light Sources (UV/Infrared): Detects biological evidence (e.g., semen, blood) or injuries not visible under standard lighting.
        • Disposable Speculum Sets: Used for internal examinations; often plastic and single-use to maintain sterility.
      • Evidence Collection Kits
        • Sterile Swabs (Dacron or Rayon): Collects DNA evidence from oral, genital, or anal areas. Must be stored in paper-based containers (not plastic) to prevent DNA degradation.
        • Evidence Collection Kits (ECK): Pre-packaged kits containing swabs, envelopes, and forms for documenting the chain of custody. Examples include the Sexual Assault Evidence Collection Kit (SAECK) used in the U.S.
        • Tollens’ Reagent and pH Strips: Chemical tests to confirm the presence of semen or vaginal secretions.
      • Medical and Safety Supplies
        • Sterile Gloves and Gowns: Prevents cross-contamination between survivors and healthcare providers.
        • Lubricating Jelly (Water-Based): Used for internal exams to reduce discomfort; oil-based lubricants can damage forensic evidence.
        • Emergency Medications (e.g., STI Prophylaxis, Emergency Contraception): Administered if the survivor consents and meets clinical criteria.
        • First Aid Supplies (Bandages, Antiseptics): Treats minor injuries or lacerations during the exam.
      • Documentation and Legal Tools
        • Tamper-Evident Bags and Seals: Secures evidence to maintain chain of custody for court admissibility.
        • Chain-of-Custody Forms: Tracks the handling of evidence from collection to legal submission, including signatures of all personnel involved.
        • Digital Storage Devices (Encrypted): Securely stores photographs and reports to prevent unauthorized access.
      • Trauma-Informed Support Materials
        • Comfort Items (Blankets, Pillows, Warm Lights): Reduces anxiety and promotes a calming environment.
        • Interpreter Services (if needed): Ensures clear communication for non-native speakers or survivors with disabilities.
        • Advocacy Resource List: Provides contact information for counseling services, legal aid, and support organizations.
      Each tool is selected based on its role in medical care, forensic integrity, and survivor-centered support. For example, the use of water-based lubricants ensures comfort during internal exams while preserving DNA evidence, whereas UV light enhances the detection of subtle injuries that could be critical in legal proceedings. Documentation in a SANE exam serves dual purposes: medical record-keeping and legal evidence preservation. The process begins during the exam, where the SANE nurse records observations in a standardized forensic report, often using templates aligned with

      Evidence Collection and Forensic Science in SANE Exams

      The Sexual Assault Nurse Examiner (SANE) exam is not merely a medical procedure but a meticulously documented forensic investigation. Evidence collected during these exams plays a pivotal role in criminal prosecutions, victim support, and public safety. Biological samples, trace evidence, and digital data are systematically gathered using standardized protocols to ensure admissibility in court. Forensic science bridges the gap between clinical assessment and legal proceedings, transforming physical and digital traces into actionable proof. Advances in technology and forensic techniques have significantly enhanced the reliability and scope of evidence collected, while strict adherence to chain-of-custody protocols remains critical to preserving integrity.

      Types of Evidence Collected During SANE Exams

      SANE exams yield a diverse range of evidence, each requiring specialized collection and preservation methods. Biological evidence, such as DNA from saliva, semen, blood, or skin cells, is foundational in linking suspects to victims. Trace evidence—including fibers, hairs, soil, or foreign substances—can corroborate narratives of assault, such as the presence of a suspect’s clothing fibers on a victim’s body. Digital evidence, though less commonly discussed, has grown in importance with the rise of technology-facilitated abuse. This includes photos, videos, or messages stored on devices, which may depict assaults, coercion, or other criminal activity. The collection of digital evidence often involves securing the victim’s smartphone, tablet, or computer under forensic protocols to prevent data alteration. Forensic tools like write-blockers or encrypted storage devices ensure that evidence remains unaltered during examination. Blockquote: "Digital evidence in SANE cases is as critical as biological samples, yet its fragility demands specialized handling to avoid deletion, encryption, or corruption." Trace evidence is collected using sterile tools, such as forceps or adhesive lifts, and placed in labeled containers to prevent cross-contamination. Each item is documented in a chain-of-custody log, which tracks its handling from collection to courtroom presentation.

      DNA Collection Methods in SANE Exams

      DNA evidence is the cornerstone of forensic investigations in sexual assault cases, providing objective proof of contact between perpetrator and victim. The collection process begins with sterile cotton swabs moistened with sterile water or saline, used to collect samples from orifices, skin, or clothing. Swabs are labeled with identifiers (e.g., "vaginal," "oral," "clothing") and stored in paper envelopes or sterile containers to prevent degradation. Blockquote: "DNA degrades rapidly in heat or humidity; thus, samples must be refrigerated (2–8°C) or frozen (−20°C) within 72 hours of collection." For clothing or bedding, dry swabs or FTA (Flinders Technology Associates) cards are used to absorb and stabilize DNA. These cards are particularly useful for field collection, as they allow samples to air-dry before storage. Once collected, samples are transported to forensic laboratories under controlled conditions, often via cold chain logistics to maintain integrity. Laboratories employ Short Tandem Repeat (STR) analysis, a gold-standard DNA profiling technique, to compare samples against databases like CODIS (Combined DNA Index System). Advances such as rapid DNA technology now enable on-site results within hours, though traditional lab processing may take weeks.

      Traditional vs. Modern Forensic Techniques in SANE Evidence Processing

      Forensic science has evolved from rudimentary techniques to high-tech methodologies, each with distinct advantages in SANE evidence processing. Traditional techniques, such as light microscopy for fiber analysis or gas chromatography-mass spectrometry (GC-MS) for toxicology, remain essential for identifying substances like drugs or accelerants. These methods are cost-effective and widely accessible but are often time-consuming and limited in scope. Modern advancements have revolutionized evidence analysis. Next-Generation Sequencing (NGS) enhances DNA profiling by identifying mixed samples or degraded DNA, while genetic genealogy uses public DNA databases to trace suspects based on partial matches. Touch DNA analysis detects trace cellular material left on surfaces, expanding the potential for evidence collection beyond direct contact. Blockquote: "Genetic genealogy has solved cold cases by linking suspects to victims through distant relatives, demonstrating the power of modern forensic innovation." Additionally, portable forensic labs and drones equipped with hyperspectral imaging are being tested for field evidence collection, reducing the need for physical transport. However, these technologies require rigorous validation to ensure admissibility in court.

      Chain of Custody in SANE Evidence and Common Pitfalls

      The chain of custody is a chronological documentation of evidence handling, ensuring its authenticity and preventing tampering. It begins at collection, where each item is labeled, photographed, and signed into a log by the SANE nurse. Evidence is then sealed in tamper-evident bags or containers, with custody transferred only to authorized personnel (e.g., law enforcement, forensic technicians). Blockquote: "A broken chain of custody can invalidate evidence, as courts require unbroken documentation from collection to presentation." Common pitfalls include:
    • Improper labeling or misidentification of samples (e.g., swapping victim and suspect samples).
    • Contamination from environmental exposure (e.g., DNA cross-transfer between samples).
    • Delayed transport leading to evidence degradation (e.g., blood samples left at room temperature).
    • Unauthorized access or missing documentation in custody logs.
      • To mitigate risks, many jurisdictions use barcode-tracked evidence kits and secure transport protocols, such as GPS-monitored couriers for critical samples. Training for first responders and lab technicians emphasizes strict adherence to standardized procedures.

      Lifespan and Preservation of SANE Evidence

      Evidence degradation varies by type, necessitating tailored preservation strategies. Below is a comparative table outlining evidence lifespan and best practices:
      Evidence Type Lifespan Under Ideal Conditions Degradation Factors Preservation Best Practices
      DNA (Swabs/FTA Cards) Years (if refrigerated/frozen); weeks at room temperature Heat, humidity, UV exposure, bacterial growth Store in sealed containers at 2–8°C; avoid direct sunlight. Use desiccants for dry samples.
      Bloodstains (Clothing/Fabrics) Decades (if protected); months if exposed to elements Light, moisture, microbial activity Air-dry completely before storage; use acid-free paper envelopes. Store in cool, dark conditions.
      Fibers/Hairs Indefinite (if uncontaminated); weeks if exposed to chemicals Oxidation, physical damage, solvent exposure Store in separate containers; avoid adhesive tapes that may damage fibers. Use forceps for handling.
      Digital Evidence (Phones/Computers) Indefinite (if stored properly); hours if battery dies or device is powered off Data corruption, overheating, physical damage Use write-blockers; store in Faraday bags to prevent signal interference. Document device state immediately.
      Photographic Evidence Decades (digital); centuries (archival film) Heat, magnetic fields, improper file formats Store digital files in multiple encrypted backups; use lossless formats (e.g., TIFF). Label physical photos with archival-quality sleeves.

      Forensic Photography in SANE Exams

      Forensic photography documents injuries, evidence, and crime scenes with precision, serving as a permanent record for legal proceedings. Specialized cameras, such as Canon EOS 5D Mark IV or Nikon D850, equipped with macro lenses (e.g., 60mm–105mm) capture fine details like bruises, lacerations, or bite marks. Blockquote: "A single photograph can depict the severity of injuries or the location of trace evidence, making it indispensable in court." Lighting is critical to avoid shadows or glare. Ring flash units or twin flash systems provide even illumination, while alternate light sources (ALS)—such as ultraviolet (UV) or infrared (IR) lights—reveal latent patterns (e.g., semen fluorescence under UV). Standardized protocols include:
    • Scale markers (e.g., metric rulers

      • The SANE exam embodies a paradigm shift in forensic medicine, where clinical expertise meets advocacy to dismantle barriers for survivors seeking justice. By combining rigorous evidence collection with trauma-informed practices, it sets a global standard for how medical professionals, legal systems, and support networks collaborate. As technology advances and legal frameworks evolve, the SANE exam remains a cornerstone of trust—one that ensures victims are heard, evidence is preserved, and perpetrators are held accountable. Its legacy is not just in the protocols followed but in the lives it helps restore.
