HIV Self-Testing in Switzerland: How It Works and Where to Get Confidential Support

Anyone in Switzerland who wants to find out their HIV status on their own has been able to do so at home since the summer of 2018. That is when the therapeutic products authority Swissmedic permitted the sale of HIV tests for self-use – the so-called HIV self-tests. Today these tests are legal and easy to obtain: in pharmacies and drugstores, in many supermarkets and also online. The Federal Office of Public Health (FOPH/BAG) and Aids-Hilfe Schweiz recommend choosing a test that carries the European CE marking. That marking shows the manufacturer has demonstrated the test is reliable and easy to use. Caution is warranted with online purchases: cheap products without quality assurance and even counterfeits circulate on the internet. Buying from a Swiss pharmacy or drugstore is the safer route.

The self-test is simpler than many expect. Using a hair-thin lancet, you prick a fingertip and place a drop of blood into the supplied container; after a short wait the result can be read. Most self-tests are antibody tests: they do not detect the virus directly but the body's response to it – the antibodies the immune system produces. This is the single most important point to understand: that immune response takes time to develop. As a result, an HIV self-test can only reliably detect an infection once at least three months have passed since the possible exposure. That span of time is called the window period.

The window period is the most common source of uncertainty – and of mistaken conclusions. A negative result is only meaningful if the last possible risk was at least three months ago. If the situation in question is more recent, the self-test cannot yet tell you anything reliable. In that case a professional testing service is the better choice: the 4th-generation rapid HIV test used there can, according to the FOPH, detect an infection as early as two weeks after a risk situation, with a reliable result available after about six weeks. So if you don't want to wait, or need clarity soon after a risk, a counselling and testing centre is a better fit than a home test.

A reactive – that is, "positive" – result from a self-test is never a final diagnosis. Self-tests are screening tests; a reactive result must always be checked with a confirmatory test at a testing centre or with a doctor. Only this second step establishes whether an HIV infection is actually present. There is good news behind this caution: HIV today is a chronic condition that can be treated well. People who learn of an infection early and start treatment can live a normal, long life – and under effective treatment are no longer infectious (the principle "undetectable = untransmittable"). So a reactive result is not a reason to panic, but a reason to contact a specialist service quickly.

For exactly this purpose there are confidential points of contact across Switzerland. The Checkpoints – specialised health centres in cities such as Zurich, Geneva, Lausanne and Basel, among others – and the regional Aids-Hilfe organisations offer anonymous HIV and STI testing together with personal counselling. At Checkpoint Zurich, for example, a rapid test result is available after around 20 minutes, while laboratory tests are reported after a few days. In counselling, risk situations are discussed, questions are answered and, if needed, the next steps are planned together. The FOPH puts it plainly: "An HIV/STI test without counselling is a missed opportunity for prevention." An overview of all counselling and testing centres can be found at the FOPH and at Aids-Hilfe Schweiz.

Queer Switzerland will keep following sexual-health topics and links to the official source for all the details. This article is information, not medical advice. Anyone who is unsure, wants help assessing a risk, or needs to understand a test result can find confidential, free or low-cost support at the Checkpoints and Aids-Hilfe Schweiz. If a self-test is reactive, the rule is simple: don't stay alone with it – contact a specialist service or a doctor for the confirmatory test. Round-the-clock emotional support is also available from Die Dargebotene Hand on the number 143.
