FAQ COVID-19

Here are a few tips:

  • Avoid strenuous physical activities for 24 hours before the sample is taken.
  • If you are asked to observe a fasting period, do not eat after 8 p.m. and do not drink alcoholic beverages, sodas or fruit juices. You can drink water. On the morning of the sample, do not have any breakfast. You may have water or black coffee without sugar or milk.
  • Sit and relax during the 10–15 minutes before the sample is taken.
  • When the sample is being taken, remember to tell the staff about any medications you are taking so that the results of your analyses are not distorted.

By following these guidelines, your examination will take place in the best possible conditions.

This test involves four steps:

1. The first blood test is taken on an empty stomach.

This is intended to measure your blood sugar while fasting. To avoid the consequences of feeling faint or ill while travelling to the lab, we advise that a relative or friend accompany you to drive you there and take you home.

2. Ingestion of a sweetened drink

3. Blood sample at H+1 (one hour after drinking the drink)

4. Blood test at H+2:

Two hours after drinking the drink, a third and final blood test will be performed.

Most analyses can be carried out without an appointment. Waiting times vary according to your time of arrival and the number of people waiting before you.

For spermology and HT21 analyses, please contact us on (+352) 27-321 before attending.

You can ask to remain anonymous when your sample is taken. Whether you have a prescription or not, you will need to tell us the name of your doctor.

It is important to collect the sample before starting your antibiotic treatment so as not to disrupt the results of the tests.

You do not need to be accompanied to have your blood test done. To make sure your analysis can be carried out, you must remember to bring your prescription and your social security card. Whether or not you have a prescription, you should always tell us the name of your doctor.

It is best to keep it in a refrigerator.

All specific or specialist samples are transported and managed by our laboratory. If an analysis is performed by a subcontracting laboratory elsewhere, we ensure that it is followed-up all the way to the final result.

You should not stop your treatment unless your biologist or doctor specifically requests it.

You can have a non-prescription analysis carried out, although you should be aware that the tests will be entirely at your own cost. You will still need to provide us with the name of your treating physician so that we can give him or her a copy of your results.

For most of routine analyses, we guarantee a distribution of the results within 24 hours.

Some analyses may take longer, for example bacteriological cultures, allergology analyses or certain serologies.

You will be informed of the deadline for the results when you take your sample.

A prescription for analyses is valid for reimbursement by the CNS for 2 months, unless a date not exceeding 6 months has been specified by the prescribing physician.


Renewable prescriptions are valid for 6 months from the date of prescription.

For reasons of confidentiality we cannot fax your results to your workplace. On the other hand, you will have direct and secure access to your results from your computer, tablet or smartphone via our MYLAB app.

If you have made an appointment online, the time will have been communicated to you.

This varies according to the number of people waiting at the sampling centre. People who have arrived before you will be seen first.

BIONEXT's partner pharmacies offer extended opening hours, making it easier for you to hand in your samples and buy medicines at the same time, while benefiting from professional supervision.

You can drop off your sample from Monday to Friday during the pharmacy's opening hours and on Saturdays. Please refer to the information sheet for each partner pharmacy.

Samples can be deposited from Monday to Friday during pharmacy opening hours. For Saturdays, please refer to the information sheet for each partner pharmacy.

Yes, you are entitled to the same benefits as a resident if you are affiliated to the Caisse Nationale de Santé and if you have a medical prescription from a Luxembourg or foreign doctor (Belgian, French or German).

Laboratory analyses offer:

  • higher reliability, with less risk of false negatives or false positives;
  • earlier detection, as the test can be performed 6 weeks after a risk situation;
  • medical support in case of a positive result — which is not always available with self-tests.

If you think you have an STI, don't panic and avoid sexual intercourse. Consult a health professional as soon as possible and undergo screening to confirm or rule out infection.

Screening for HIV, hepatitis B and C, and syphilis on a blood sample as well as screening for chlamydiosis (Chlamydia trachomatis) and gonorrhea (Neisseria gonorrhoeae) on a urine sample.

If you have had high-risk sexual relations, consult a healthcare professional to find out when you should be tested. Some tests need to be carried out up to 6 weeks after risky sex in order to be reliable (e.g. HIV).

BIONEXT participates by making screening accessible in its laboratories and via its mobile units ("LABOMOBILE") throughout Luxembourg: without appointment, free of charge, without prescription. 
During the European Testing Week, blood and/or urine analysis costs are covered by BIONEXT.
Outside these periods, you must have a medical prescription for this to be covered by the National Health Fund, provided that you are affiliated with it.

If you are positive, you should follow the prescribed treatment, avoid sexual relations until you have recovered (if applicable), and inform your partners so that they can also be tested.

The issue is:
- to offer the possibility of knowing one’s status vis-à-vis an underlying IST;
- to improve the existing offer for early management before complications appear;
- to reduce the transmission of STIs within the population.

You can be accompanied by your GP or a specialist (gynaecologist, urologist) or by associations specialising in sexual health. If you take your test at the BIONEXT laboratories, we can also help you if your result is positive.

Residents of Luxembourg as well as cross-border workers (workers or students) can access these tests in the BIONEXT laboratories.

A STI (Sexually Transmitted Infection) is an infection that is transmitted mainly through unprotected sexual intercourse (vaginal, oral, anal), but also through blood or from mother to child. Some infections have no symptoms, but can lead to serious complications if left untreated. The most common are HIV, chlamydia, gonorrhoea, syphilis, herpes, papillomavirus (HPV) and hepatitis B/C. Regular screening and condom use are the best means of prevention.

Yes, everyone can get tested.

European Testing Week is an awareness-raising campaign held twice a year, in spring and autumn, to encourage STI screening. To mark the occasion, free, no-prescription, no-appointment tests are offered at a number of venues in Luxembourg.

Yes, but we advise you to share your identity for better tracking of your results.

The initiative, supported by BIONEXT, aims to promote the prevention of sexually transmitted infections (STIs) through information and screening.
This dedicated week facilitates access to free screening in Luxembourg, without a prescription, for the main STIs (HIV, hepatitis B and C, syphilis, chlamydia and gonorrhoea).

If the result is positive, the medical team of the BIONEXT laboratory receives the patient in consultation to initiate his/her management. This is what makes all the difference with a self-test, which is not supervised by a healthcare professional.

If the screening is anonymous, the patient comes to collect his results on site, at the Leudelange laboratory - 2-4, rue du Château d'Eau. The medical team will be at his disposal to guide him in his care if necessary.

There are many STIs, the most common of which are :  HIV, Hepatitis B & C, Syphilis, Chlamydia, Gonorrhoea, but there are also genital herpes, papillomas virus and Trichomoniasis.

STIs are not necessarily symptomatic and may go unnoticed. Screening is therefore the only way to know your status vis-à-vis an STI. This allows to avoid potentially serious consequences but also to break the chains of transmission of these diseases.

No specific preparation is required before taking a test. Screening does not require fasting.

No, an STI does not always cause symptoms - it can be silent, especially at first, but remain contagious and cause complications if left untreated.

No.
A blood test will screen for HIV, hepatitis, and syphilis.
A urine sample will be used to screen for gonorrhea or chlamydia.

Yes, you can choose to perform the tests you wish. However, we advise you to carry out all the tests in order to fully benefit from this screening opportunity.

Yes, STIs can be transmitted during oral sex (fellatio, cunnilingus), even without penetration or ejaculation. Wearing a condom reduces this risk.

A self-test (or Rapid Diagnostic Orientation Test = TROD) allows for the detection of HIV, Hepatitis C, or Syphilis. It is performed by taking a drop of blood from the fingertip. Mixed with a reagent, this produces a result within a few minutes.
To be interpreted correctly, TRODs must be carried out at least 12 weeks after the risk situation. Testing earlier may lead to a false negative result. TRODs help to guide diagnosis but must always be confirmed by more accurate laboratory tests.

A laboratory screening test is performed using a blood or urine sample. These are based on more reliable analytical methods than TRODs.
Samples are analyzed in a laboratory and results are usually available within the same day.
To ensure correct interpretation, serological tests (HIV, hepatitis, syphilis) must be done at least 6 weeks after a risk situation. Urine tests can be performed 5 days after exposure.

It will take less than 5 minutes to complete all the tests. You can still save time by pre-registering via MYLAB upon your arrival in the laboratory or at the LABOMOBILE.

By using a condom every time you have sex (vaginal, anal or oral), getting tested regularly and talking to your partners about it.
