Also known as: HIV, PrEP, Prophylaxis

Clinical Use

Order Test

Use

This profile aligns with current guidelines for monitoring female 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. Client must clearly label the site/source of each Chlamydia/Gonococcus Nucleic Acid Amplification specimen. It is recommended to ask all patients who may be indicated for testing about biotin supplementation. Patients should be cautioned to stop biotin consumption at least 72 hours prior to the collection of a sample.

Limitations

HIV p24 antigen/antibody specimens with reactive results must be investigated by additional supplemental tests. A negative test for an individual does not preclude exposure to or infection with HIV-1 and/or HIV-2. Negative results can occur if the quantity of the marker present in the sample is too low for detection by the assay or if the marker is not present during the stage of disease in which a sample is collected.
