HIV, Syphilis, Chlamydia, and Gonorrhea Test

Our tests for HIV, syphilis, chlamydia, and gonorrhea help you quickly and reliably find out if you have an STI. HIV rapid tests give you results in just 20 minutes, while syphilis and bacterial tests are checked in a lab. If a test comes back positive, we recommend more checks to confirm the diagnosis and make sure you get treatment quickly.

What's the HIV rapid test all about?

  • We use rapid tests because you get your results in just 20 minutes.
  • These are 4th generation tests, and they're super accurate.
  • For the rapid test, we take a few drops of blood from your fingertip with a tiny prick (it's called a capillary blood sample).
  • This rapid test is an HIV combination test, which means it can find both HIV antibodies and the P24 antigen.
  • After a risky situation, an HIV rapid test will only show accurate and reliable results after six weeks.
  • If you get tested earlier, the result won't be accurate, and you'll need to repeat the test after six weeks. So, we recommend getting tested after six weeks.
  • If a rapid test is reactive, you'll need a confirmation test with a blood sample taken from a vein.

What's the syphilis test?

  • It's a blood test (also called a serological test) where we take a small amount of blood from your vein.
  • Your blood sample is checked at the Dr. Risch lab to look for antibodies against the bacterium Treponema pallidum.

When's the best time to get tested?

  • This test is most useful starting 6 weeks after you might have been exposed to the infection. That's because antibodies can only be reliably detected then.

How does the test work?

  • We do a screening test (RPR or VDRL).
  • If the result is reactive, we'll do a confirmation test.
  • An infection is only confirmed if both tests come back positive.

Things to know

  • Previous infection: If you've had syphilis before, please let the counselor know.
  • Reactive result: You'll get a text message suggesting you see a doctor. It will also include your lab results, which you can show them straight away.

Why is this test important?

  • If syphilis is found early, it can be easily treated with antibiotics.
  • Finding it early stops serious, long-term health issues.
  • If your partners might be affected, it's super important to let them know and get them tested too.

When will I get the results?

  • You usually get your results in 2 to 5 days.
  • We'll text you about what to do next.

What's the Chlamydia and Gonorrhea test?

  • It's a swab test where we gently collect small samples from specific areas of your body.
  • The process is painless.

What do we test for?

  • Chlamydia and gonorrhea – both are infections caused by bacteria.
  • These can spread quite easily through sexual contact, for example:
  • Petting
  • Oral sex
  • Vaginal or anal sex
  • Sharing sex toys
  • Kissing (rare, but possible)

Where do we take the swab from?

  • Depending on the person and their sexual practices:
  • Throat
  • Urethra opening (for people with a penis)
  • Vaginal lining (for people with a vulva)
  • Anus

How do we take the sample?

  • We use little swabs to gently collect samples from your mucous membranes.
  • These samples then go into tubes with a special liquid to keep them safe.
  • After that, they're sent to Dr. Risch's lab to be analyzed.

When will I get my results?

  • Results are usually ready in 2–5 days.
  • If your test is positive:
  • We'll send you an SMS advising you to start antibiotic treatment with a doctor.
  • Important: Make sure to tell your sexual partners too, so they can get tested and treated if needed.
