According to the BHIVA/BASHH guidelines on the use of HIV pre-exposure prophylaxis, prior to the initiation of PrEP, all sexually active adults should have testing to screen for chlamydia, gonorrhea, and syphilis. NAAT testing for chlamydia and gonococcal infection should be performed at the sites of exposure (genital, rectal, pharyngeal).
HIV testing is required prior to the initiation of PrEP. A blood sample should be obtained and sent to the laboratory for baseline testing with a combined antigen/antibody serology test. Screening for HIV infection should not be done with an oral rapid test as these are less sensitive for the detection of acute or recent infection than blood tests.
Testing for hepatitis B is recommended for all patients before starting PrEP. Screening for hepatitis C is also recommended in men who have sex with men and among those at high risk for hepatitis C, such as injection drug users.
