Package of tests and procedure

With Testlab, you can arrange for free and anonymous testing for STIs without having to go to your family doctor or an STI clinic. Testlab will test you for gonorrhea, chlamydia, syphilis and HIV.

The procedure involves four easy steps:  
1) Request a test online.
2) Go to a laboratory with a referral letter.
3) Get the Testlab results online.
4) If necessary: go to the GGD for treatment or further testing.

1.    Package of tests: four STIs

Testing for HIV and other STIs via Testlab is free and anonymous. Via Testlab you will automatically be tested for the four most important STIs: gonorrhea, chlamydia, syphilis and HIV. These STIs often have no symptoms. That is why it is important to get yourself tested on a regular basis. You might have an STI without knowing it.

2.    Automatically tested for HIV

  • If you do not want to be tested for HIV, you will need to indicate that in advance on the request form. In that case, the HIV test will not be carried out. 
  • If you indicate that you are HIV positive, the HIV test will automatically be removed from the package of tests. 

3.    Step 1: Request a test online.

If you want to get tested via Testlab, you will first need to fill in the Testlab request form. That will determine whether or not you are eligible for the online STI test. At the end of the questionnaire you can indicate whether or not you would like to be tested for HIV. Testlab is a collaborative project with the GGD. The questionnaire contains the same standard questions that you would have to answer at any STI clinic. These are obligatory questions that we need to ask in connection with the registration and compensation of STI tests.

Once you have filled everything in, you will receive a PDF file consisting of three documents:

  • a referral letter that you will need to bring with you to the laboratory of your choice
  • a request form, including a personal code for your own records
  • a list with addresses of all testing locations near you.

Save the request form and print it out. The form contains a personal code that you will need in order to get your test results.

  • Tip: Have you printed out the request form without having saved it first? In that case, make a copy of the form (e.g. using your cell phone) before you go to the laboratory.

4.    Step 2: Go to a laboratory with the referral letter.

With your personal referral letter you can go to one of the participating laboratories in your region. You do not need to make an appointment for that. When you arrive at the laboratory, present yourself at the reception desk and hand over your referral letter there. Next you will be asked to provide a urine sample, a lab worker will draw blood and swabs will be taken of your throat and anus. This procedure is anonymous. You don't need to answer any personal questions at the laboratory.

In order to test for these four STIs, different materials will be sampled.

  • For syphilis and HIV, a lab worker will draw blood samples.
  • For gonorrhea and chlamydia, you will need to provide a urine sample and two small cotton-tipped swabs will be used to take samples from your throat and anus. The throat swab will normally be done by the lab worker. You will be asked to do the anal swab yourself in a specially designated room.

5.    Step 3: Get your Testlab results online.

The Testlab results will normally be available seven to ten days after your visit to the laboratory.

  • Log in via to retrieve your test results.
  • Use your personal code for this. You will find that code on the request form and on the referral letter. Be sure to keep the code in a safe place.
  • Your personal code relates to this particular request for testing. Never use old personal codes from previous Testlab requests.

Do the test results show that you have an STI? In that case, the online results will not specify which STI it is. For the specific results and for immediate treatment, you will need to go to your nearest STI clinic or GGD. You can expect to receive one of the following four statements of results online:

  1. The results of all the tests were good: You do not have HIV or any other STI. With this result you can indicate whether you would like to be reminded to get tested again in six months' time.
  2. You have one or more STIs but not HIV. The test results show that you may have one or more STIs (chlamydia, gonorrhea and/or syphilis). If you were also tested for HIV, the results of that test are negative (which means you do not have HIV). The online results page will tell you what you need to do next. Log in to for this.
  3. One or more of the tests will need to be repeated or confirmed. This could happen when one of the tests was positive (which means you have one or more of the STIs tested), but it is not possible to be certain on the basis of the samples taken. That could be the case with sample materials that provide unclear test results or with non-standard test results that need to be confirmed or repeated. The online results page will tell you what you need to do next. Log in to for this.
  4. One or more of the tests failed and will need to be done again. That could be the case, for example, if material samples were improperly taken or if there was a problem in the laboratory. The online results page will tell you what you need to do next. Log in to for this.

Step 4: If necessary: go to the GGD for treatment or further testing.

We advise you to request your results during office hours (and before 15.00 on Friday). That way, if necessary, you can go to the STI clinic for treatment or further testing as soon as possible. In most regions, it is not possible to get your results by telephone. The administrative staff of the STI clinics have no access to your information.

Here are possible next steps:

  • Did the tests detect chlamydia, gonorrhea and/or syphilis? In that case, you will receive immediate treatment at the GGD. That will normally consist of a one-off treatment with antibiotics or a short course of treatment with antibiotics.
  • Did the test detect HIV? In that case, you will be referred to an HIV treatment centre for further advice and treatment. There you will receive personal guidance from trained doctors and nurses.
  • Was it not possible to provide reliable results on the basis of the samples taken for the test? In that case you will receive further testing at the GGD to know for sure whether or not you have an STI.
  • Besides providing treatment, the GGD can also help you notify your sex partners. They could also have an STI without knowing it.
