What HIV is, in 2026 terms

HIV is a virus that attacks the immune system. Left untreated it progresses to AIDS. Treated, it does neither of those things: people on effective antiretroviral treatment have a normal life expectancy, and the virus is suppressed to the point where it cannot be transmitted sexually.

That last point has a name. Undetectable equals untransmittable, usually written U=U, is the finding that a person on treatment with a sustained undetectable viral load does not pass HIV to sexual partners. It is not a hopeful theory; it is the conclusion of large studies and it is accepted by health authorities internationally.

Which reframes what an HIV test is for. It is not a verdict. It is the thing that gets you onto treatment early, which is what makes the outcome ordinary.

How HIV is tested at Epicentre

There are three ways to test, all of them requiring a branch visit because all of them need blood.

If you want a result today, or you need a certificate, take the rapid test. If a few days is fine and you want the earlier-detecting 4th-generation lab test, take the antibody test. If you are already having a PCR panel done, the R524 combined add-on is the sensible companion, because it closes the gap the panel leaves.

When to test after exposure

The 4th-generation lab test is generally reliable from around 2 weeks after exposure, because it detects the p24 antigen, which appears before antibodies do. Antibody-only tests take longer.

Testing a baby

Infant HIV testing is available from 6 weeks of age, at R690. It requires a branch visit, and the team confirms which test is used and the sample type when the booking is made.

If your baby is under 6 weeks old, contact the branch rather than booking, because testing that young needs the team to advise. Infant testing follows a schedule of repeat tests, and only a clinician can interpret where a child is in it.

If you are already on treatment

The HIV Treatment Monitoring panel at R1,562 covers CD4 count, viral load and organ function, with a full blood count, creatinine, AST and ALT. Results in 2 to 5 working days. No doctor's referral is needed to have it done, and the results go to whoever manages your treatment.

Your result, and what happens next

You get one report, emailed to you and to nobody else. It is the YourGenes patient report: colour coded, in plain language, with a line for every organism on your panel saying whether it was detected. There is no second document, and no separate practitioner version. This report is what your doctor reads too.

If HIV is detected, Epicentre does not treat it. We are a diagnostic laboratory. We collect samples, run tests and report results. We do not diagnose, prescribe medication or provide treatment, anywhere, including on WhatsApp. You have two equally good routes from here:

• Your own doctor, clinic or pharmacy clinic. Take the report. It names the organism, which is exactly what they need.
• An independent doctor we work with, who consults online or in person on sexual health results. She prescribes on her own responsibility, not as an Epicentre service.

For HIV specifically, a reactive screening result always needs confirmatory testing, and starting treatment is a clinical process. The independent doctor we work with runs an HIV and PrEP programme, and your own doctor or any public clinic can do the same. Treatment is available free through the public system in South Africa.

Where to test

Walk in during those hours, no appointment and no doctor's referral. All three branches are closed on South African public holidays. If you would rather not come in, a home kit is couriered to you in discreet packaging and a free courier collects the sample.
