STD testing refers to a group of blood tests that check for common sexually transmitted infections. It is ordered to screen for infections that may not cause symptoms, or to confirm a suspected exposure.
What it measures
- HIV antibody/antigen — Detects the virus that causes AIDS.
- Syphilis (RPR or treponemal) — Screens for the bacterium that causes syphilis.
- Hepatitis B surface antigen — Shows current hepatitis B infection.
- Hepatitis C antibody — Indicates past or present hepatitis C infection.
- Herpes simplex virus (HSV) antibody — Detects prior exposure to oral or genital herpes.
Who it is for
A clinician may order STD testing for anyone who is sexually active, especially with new or multiple partners, or who has symptoms or a known exposure. It is also part of routine care in many settings.
Preparation
No fasting is required. Tell your clinician about any medications or recent exposures, as timing may affect test selection.
Results and what they mean
Results are reported as negative or positive, sometimes with a numeric value. A positive result does not always mean an active infection; a clinician interprets all results in context. This is general information, not medical advice.
