Complete STI
Screen

HIV – For accuracy the best time to take the test is 6 weeks after exposure, however early detection tests can be taken 10 days post exposure. This test measures blood levels of HIV p24 antigen which are high in the first few weeks after infection, meaning the test can detect infection in the earliest stages.

Hepatitis B and C – You should get tested for Hepatitis B and Hepatitis C 3 months post exposure. It can take up to 3 months for these viruses to become detectable in the blood.

Syphilis – You can test for Syphilis from 3-6 weeks after exposure. If you test too early you may receive a false negative result. It can take up to 3 months for Syphilis to be detectible in your blood and a test 3 months after exposure is recommended to exclude infection.

HIV – This test specifically measures HIV-1 p24 antigen and antibodies to HIV-1 including group O and HIV-2

Hepatitis C – This test detects antibodies specific to Hepatitis C Virus

Hepatitis B – This test detects Hepatitis B surface antigen in the blood

Syphilis – This test measures total antibodies to Treponema pallidum (syphilis)

Please note if any results indicate that you have tested positive (reactive) for any of the infections you will need to book in for a consultation with either your usual GP or our clinic doctor for initiation of treatment or referral to a hospital with a sexual health clinic.

The Complete STI blood test is suitable for anyone if you want to rule out the possibility of having HIV, Syphilis and Hepatitis B or C.
