What are the differences between Sexual Assault Kit Exams (SAKEs) and Early Evidence Kits (EEKs)?

Accessibility: Location & Cost

A Sexual Assault Kit Exam is performed in-person in a hospital or care center, typically by a sexual assault nurse examiner (SANE). Under VAWA, a Sexual Assault Kit Exam must be free, but your payment or insurance information may be collected. Find the closest Sexual Assault Exam location.

An Early Evidence Kit (EEK) is performed at-home with optional live support from a 24/7 virtual care team. If you are eligible for an Early Evidence Kit, it will be delivered discreetly to the address of your choice in under two hours. Eligibility is dependent on a number of factors, most importantly your physical wellbeing. Leda Health’s Early Evidence Kits are paid for by community partners, like organizations and universities. No payment or insurance information is collected. Access an Early Evidence Kit.

Procedures: Length & Detail

A Sexual Assault Kit Exam is more invasive than an Early Evidence Kit, but it provides more comprehensive DNA collection as well as an in-person physical examination. An average exam is approximately four hours long. Sexual Assault Kit Exams are in-depth, collect DNA from more parts of your body, and may additionally comb and pull pubic hairs for collection. Comprehensive photographs may be taken, anatomical drawings may be completed, and follow-up services may be offered.

An Early Evidence Kit is less invasive than a sexual assault exam, but it does not provide as comprehensive DNA collection or a physical examination. EEKs may be completed autonomously (on your own) in under one hour. DNA is collected from two parts of your body, and one item, such as underwear, may be submitted for additional testing. No pubic hair is collected. Photographs and digital statements may be collected via Leda’s mobile app (optional), where they will be securely stored with timestamps. EEKs include optional emergency contraception and at-home STI testing, but no in-person services. Note: You may complete an EEK prior to receiving in-person care, but it is not a replacement for a comprehensive physical examination.

Additional Services: Medication & Care

Early Evidence Kits provide optional emergency contraception (EC) as well as at-home STI testing delivered 2-3 weeks later. Hospitals and care centers provide more comprehensive services and medications, including post exposure prophylaxis (PEP), which may help prevent HIV after potential exposure. We recommend that you seek in-person care if you are interested in these services or would like to inquire about follow-up care. Find local care quickly.

Drug-Facilitated Sexual Assault

Early Evidence Kits do not provide toxicology services and are not intended for drug-facilitated sexual assault. We recommend that you seek in-person care if you were drugged. We can help you find the closest care center.


It is important to note that admissibility of trial evidence is never predetermined or guaranteed. The admissibility of all evidence, whether collected via SAKE or EEK, goes through the same process. It cannot be determined in advance, as it is decided by the trial judge on a case-by-case basis.

SAKEs are the “traditional way” of reporting and qualifying sexual assault. They are the standard kit presented in court today, and there is a strong precedent for the admissibility of evidence collected this way. SAKEs do not guarantee admissibility in court as it is always up to a judge or jury to decide.

EEKs provide a new way to collect DNA autonomously after assault. Past case law demonstrates the admissibility of self-collected evidence, but it is always up to a judge and jury to decide. EEKs do not guarantee admissibility. We cannot guarantee that any information collected through our Early-Evidence kit will be offered, admitted, or relied upon in a court of law. The ultimate admissibility and reliability of information that you collect through Leda Health’s services will be dependent on the specific circumstances of your case and applicable law. To obtain the full benefits of our service, you must carefully read and follow all related instructions.
