PrEP, Male, Injectable Monitor + HIV RNA
Also known as: HIV, PrEP, Prophylaxis
Use
This profile aligns with current guidelines for monitoring male patients on injectable HIV PrEP.
Special Instructions
The test requires a dedicated, unopened, gel-barrier tube, and either a frozen or refrigerated serum pour-off tube for collection. It's important to note that high doses of biotin (vitamin B7) can interfere with the results, so patients should stop biotin consumption 72 hours before sample collection. This is crucial for accurate testing, especially when evaluating patients who may be on or considering PrEP therapy.
Limitations
Reactive results in HIV p24 antigen/antibody testing must be followed by additional supplemental tests. Negative results do not exclude the possibility of HIV exposure or infection, as these can occur if the marker quantity in the sample is insufficient for detection or if sampling occurs during a disease stage where the marker is not present.
