Requirements · testing · guidelinesPrEP requirements: who qualifies, the tests & the guidelines
Getting PrEP is simpler than most people think — but there are a few requirements: you need to be HIV-negative, have some baseline blood work, and check in regularly. Here's exactly who qualifies, what tests you'll have, and what the CDC, WHO and USPSTF guidelines say.
✅ Who qualifies for PrEP?
US guidelines say PrEP should be offered to anyone HIV-negative who asks for it, and actively recommended if any of these apply:
- A sexual partner living with HIV (especially if not virally suppressed).
- Condomless anal or vaginal sex with partners whose status you don't know.
- A bacterial STI (syphilis, gonorrhoea, chlamydia) in the past 6–12 months.
- You share injection equipment.
- You've used PEP and remain at ongoing risk.
🧪 PrEP blood work & testing requirements
PrEP comes with a small, standard set of tests — before you start and then at check-ins. This is what keeps it safe and effective.
| When | Tests | Why |
|---|---|---|
| Before starting | HIV test (negative), kidney function (creatinine/eGFR), hepatitis B — usually STI screen & pregnancy test | Confirm you're HIV-negative and safe to start |
| Every 3 months | HIV test + check-in; STI testing | Catch any infection early; refill |
| Every 6–12 months | Kidney function; hepatitis C as needed | Ongoing safety monitoring |
📋 What the CDC, WHO & USPSTF guidelines say
- CDC (2021 PrEP guideline): discuss PrEP with all sexually active adults and adolescents, and prescribe it to anyone at risk who wants it.
- USPSTF (2023): gives PrEP its highest "Grade A" rating — which is why US insurers must cover it, and its lab visits, at no cost.
- WHO: recommends PrEP for anyone at substantial risk of HIV, as part of combination prevention.
In short: the guidelines have moved from "PrEP for special groups" to "PrEP for anyone who could benefit."
