Preparing for your blood test
Precautions to take before blood sampling
Generally speaking, you should avoid physical activity for 24 hours prior to sampling, and avoid eating a meal rich in sugar or fat. Consumption of certain types of food may interfere with the results.
If your prescription states “fasting” or “nil by mouth”:
The night before (nil by mouth for at least 8 to 12 hours’) :
- Do not eat
- Do not drink any alcoholic or sweet beverages
- You can however drink water
The day of the test :
- Do not eat breakfast
- You can however drink water or coffee without sugar or milk.
If you have any doubts or questions, please do not hesitate to contact our laboratory on (+352) 488 288-1.
What documents should I bring ?
Before going to the laboratory, always bring the following with you:
- Your doctor’s prescription
- Your CNS card and/or EHIC
Some analyses also require you to bring other documents:

Receipt of results
Most test results are available the same evening if the blood sample was taken in the morning. Some analyses may take longer, such as bacteriological cultures, allergology analyses or certain serologies. In these cases, you will be informed of the time required to obtain your results when you take your sample.
When your results are available, you will be notified by SMS to go to our results server. This SMS contains a link and an identifier allowing you to consult your results.
When should I have my sample taken ?
The best time to take your sample is in the morning, before 10am. That’s why most of our laboratories are open from 6:30 am.
In emergencies or special cases, we are also open in the afternoons from 1pm to 6pm. You will find all our laboratory opening times in the “Our laboratories” section.
Some blood parameters measured in the laboratory change during the day. For this reason, you may be asked to have your blood sample taken in the morning, or to have your doctor note down one or more specific times of the day for the blood test to be taken. For certain specialized tests, you will need to make an appointment. Simply contact Laboratoire Ketterthill at 488 288-1.
