HIV, Syphilis, Gonorrhoea and Chlamydia: Which Test Do I Need?

Make the infection list explicit

HIV and syphilis commonly involve blood testing, while gonorrhoea and chlamydia testing may use urine or swabs. The appropriate sample depends on the infection and the exposed site. A blood sample alone does not mean every possible infection has been checked.

Describe the sites of contact

Tell the clinician whether you had oral, vaginal or anal contact, and whether you have symptoms. CDC advises discussing throat or rectal testing after relevant exposure. Do not assume that a urine result answers a question about every other site.

Ask about timing and treatment

Different infections have different testing considerations. Ask when to test, whether symptoms need treatment assessment now, and when follow-up is needed. Avoid taking leftover antibiotics or relying on a home HIV result to decide that a symptom has no cause.

Prepare a clear appointment checklist

Bring exposure dates, prior diagnoses and treatment records. Ask for the test names, samples, cost, result collection method and follow-up contact. If a partner has a confirmed infection, tell the clinician which one. Keep a copy of the final report so future appointments can use accurate information.

Common questions

Does an HIV home kit cover gonorrhoea?

No. Check each product’s intended use; an HIV-only kit screens for HIV only.

Can I need STI testing without symptoms?

Yes. Some infections can be present without noticeable symptoms. Ask which screening is appropriate for you.
