PrEP, Male, Oral Baseline + HIV RNA

Also known as: HIV, PrEP, Prophylaxis

Clinical Use

Order Test

Use

This profile aligns with current guidelines for assessment of male patients prior to the initiation of oral HIV PrEP.

Special Instructions

Not provided.

Limitations

Results of HIV p24 antigen/antibody testing must be confirmed by additional tests if reactive. Negative results do not rule out HIV-1 and/or HIV-2 infection due to potential low marker quantity or absence during disease stages. GFR estimates based on serum creatinine may be inaccurate for patients at muscle mass extremes, with unusual diets, or conditions affecting creatinine secretion or elimination.
