Pre-exposure prophylaxis (PrEP) is a highly effective medication regimen used for HIV prevention.
However, in people taking PrEP or post-exposure prophylaxis (PEP), the low levels of HIV may be missed by current testing methods. The blood community relies on accurate HIV testing as part of its multilayered approach to safety. There needs to be more research on how PrEP and PEP affect HIV testing. Currently, the FDA recommends that individuals who take oral PrEP or PEP be deferred from donation for three months from their most recent dose. For individuals who have received PrEP by injection, the FDA recommends deferral from blood donation for two years from their most recent injection. This is an issue impacting blood operators worldwide. Tests used to detect HIV and other viruses are manufactured by independent companies, not blood collectors or regulatory bodies. Work to understand the true impact of PrEP and PEP medication regimens on HIV tests can only be completed in collaboration with or directly by the manufacturers of the test, who hold the licensing for these products.
DO NOT STOP TAKING ANY PRESCRIBED MEDICATIONS IN ORDER TO DONATE BLOOD, INCLUDING PrEP and PEP MEDICATIONS.
