Screening tests

Screening tests

Screening detects the antibodies that are produced by the body following contact with the HIV virus. The antibodies are not detected until 1 to 3 months after infection.

  • Blood-sample screening tests can detect both HIV-1 and HIV-2 antibodies. These antibodies can be detected 3 weeks after infection. If the test is negative, the test will be reliable for 6 weeks after the blood sample is taken, and for 3 months after an RDT (rapid diagnostic test) or self-test.
  • Rapid diagnostic tests do not require any special equipment. If the test is positive, it must be confirmed using a blood sample (2nd test).
  • Direct blood tests can detect the virus.

Rapid diagnostic test or RDT

A rapid diagnostic test (or RDT) can be used to detect HIV infection.

A drop of blood is taken from the fingertip and mixed with a reagent. The result appears a few minutes later.

For the result to confirm that there is no infection, the rapid test must be carried out at least 12 weeks after the high-risk encounter.

Important!

Taking a rapid test means that the result is obtained quickly after the blood is taken, not that the test is reliable immediately after a high-risk situation!

Where can you take an RDT?

Rapid tests (or RDTs) can be taken anonymously, free of charge and without an appointment:

  • At the Luxembourg Red Cross HIV-Berodung, 94, bvd Général Patton L-2316 Luxembourg
    Every Monday and Wednesday from 17:00 to 19:00.
  • At the DIMPS - Mobile HIV Testing: A mobile unit that goes out into the community with the aim of expanding free, anonymous screening. The times and locations for the DIMPS service can be found on the www.dimps.lu website, or on the DIMPS Project Facebook page.

Self-testing

Self-testing makes it easier to get screened for HIV. The test can be purchased from pharmacies or CACTUS supermarkets and taken alone, at home or elsewhere, without the need for a healthcare professional to be present.

In the context of the COVID-19 pandemic:

The HIV self-test can also be ordered free of charge from HIV Berodung to ensure continued access to HIV screening. This free offer is available upon request by calling 27 55 4500, or by sending an email to hivberodung@croix-rouge.lu.

Before taking a self-test:

It is essential to read the instructions and the information leaflet carefully, and to prepare yourself for the fact that, in just a few minutes, you will have an HIV test result.
