PrEP, Female, Oral Monitor + HIV RNA
Also known as: HIV, PrEP, Prophylaxis
Use
This profile aligns with current guidelines for monitoring female patients on oral HIV PrEP.
Special Instructions
The test profile requires the use of a dedicated, unopened gel-barrier tube and a frozen (preferred) or refrigerated serum pour-off tube. It is crucial for clients to clearly label the site/source of each Chlamydia/Gonococcus Nucleic Acid Amplification specimen. Additional testing time may be necessary for confirmatory or reflex tests. Patients taking high doses of biotin should stop intake at least 72 hours before specimen collection due to potential interference.
Limitations
Negative results do not rule out the possibility of HIV exposure or infection. False negatives may result if the antigen or antibody quantity is too low for detection or if the disease stage at the time of sample collection does not coincide with presence of detectable markers. Reactive HIV p24 antigen/antibody results need further investigation through supplemental testing to ascertain an HIV diagnosis.
