PrEP, Male, Oral Monitor (No HIV RNA)
Also known as: HIV, PrEP, Prophylaxis
Use
This profile aligns with current guidelines for monitoring male patients on oral HIV PrEP.
Special Instructions
This profile requires a dedicated, unopened, gel-barrier tube and a frozen (preferred) or refrigerated serum pour-off tube. It is recommended to ask patients about biotin supplementation as high doses may interfere with test results. Patients should stop biotin consumption 72 hours prior to sample collection.
Limitations
Specimens with reactive HIV p24 antigen/antibody results must undergo additional supplemental tests. A negative result does not rule out HIV-1 or HIV-2 infection, which can occur if the marker quantity is too low or absent at the time of collection.
