I need to do an oral glucose tolerance test (OGTT). What should I do?
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.

4. Blood test at H+2:
Two hours after drinking the drink, a third and final blood test will be performed.

Do you carry out non-prescription analyses?
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.
Will I have to wait a long time in the waiting room?
This varies according to the number of people waiting at the sampling centre. People who have arrived before you will be seen first.
Are there any precautions to take before a blood sample is taken?
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.

Regular screening and condom use are the best means of prevention.
What's the European Testing Week?
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.

What is the main objective of the European Testing Week?
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).
Why is it important to get tested for STIs?
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.
Do all STIs detect themselves in the same way?
No.
A blood test will screen for HIV, hepatitis, and syphilis.
A urine sample will be used to screen for gonorrhea or chlamydia.
What is the difference between a self-test and an IST test in the laboratory?
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.
How do IST laboratory screening tests like BIONEXT differ from self-testing?
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.
What types of analyses are offered free of charge during the European Testing Week?
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.
How does BIONEXT engage in the European Testing Week campaign?
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.
What is the point of offering free STI screening?
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.
Who can benefit from these STI screening tests?
Residents of Luxembourg as well as cross-border workers (workers or students) can access these STI screening tests in the BIONEXT laboratories.
Are the IST tests aimed at everyone?
Yes, anyone can participate in STI screening.
Can a IST test be done anonymously?
Yes, an STI test can be done anonymously.
However, we advise you to share your identity so that your results can be better tracked.
What happens if the result of IST tests is positive?
If the result to IST tests 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.
Do we need to prepare before taking an STI screening test?
No specific preparation is required before taking a test. You do not need to fast before an STI test.
Can I choose what type of IST test to do?
Yes, you can choose to perform the IST tests you wish. However, we advise you to carry out all the tests in order to fully benefit from this screening opportunity.
What is the estimated time to receive their test results following the IST screening test?
It will take less than 5 minutes to complete all the IST tests.
You can still save time by pre-registering via MYLAB upon your arrival in the laboratory or at the LABOMOBILE.
What is the purpose of pre-registration of a prescription?
Pre-registration of your prescription allows you to simplify and speed up your visit to the laboratory.
- Fast and convenient: your file is prepared before your arrival for more efficient care.
- Accessible 24/7: with or without a MYLAB account.
- Secure: your health data is fully protected.
Pre-registration does not affect the reliability of the service; it is simply a time-saving solution for patients.
Your prescription is entered in advance, which facilitates file processing and reduces waiting time at the laboratory.

Why does vitamin D decrease in winter?
In winter, the sunshine is weaker. Vitamin D is produced by the skin under the action of sunlight, which can lead to a decrease in its production.
How do you know if you are lacking vitamin D?
A vitamin D deficiency can be detected through a simple blood test performed in a medical laboratory, such as BIONEXT for example.
Can one measure their vitamin D level by blood test?
Yes. Vitamin D levels can be measured by a blood test prescribed by your doctor. This analysis checks whether your body has a deficiency or insufficient level of vitamin D.
Based on this prescription, you can have your blood drawn at any BIONEXT laboratory. Our collection centres welcome you to perform this analysis under the best conditions.
