IS FASTING BEFORE AN EXAM NECESSARY?
Food intake can affect the results of some tests. This is particularly the case for sugar and fat: a simple coffee can disturb these findings. In addition, triglycerides, transaminases, glucose, leukocytes, bilirubin, and potassium may be distorted from 10% to 50% after an average meal.
Some results are somewhat distorted (less than 5%) by the ingestion of food. This is particularly the case of sodium levels, cholesterol, calcium, protein and the number of erythrocytes.
Finally, when testing for antibody or serology food intake has no effect on the results. It is not required to be fasting in these cases.
WHAT IS THE RIGHT TIME FOR MY BLOOD TEST?
Some blood parameters measured in the laboratory change depending of the time of day. They say they are subject to a circadian rhythm.
This is why, regardless of the need for fasting or not, you may be asked to submit to the blood test in the morning.

This collection is made possible in the laboratory, it is necessary in all cases to minimize the time between urination and cultivation.
For a simple search like albumin and sugar on a sample collection conditions are comparable, but asepsis is not necessary.
Examinations of urine produced in 24 hours
The goal is to collect all of the urine produced by the kidneys within 24 hours. To do this, it is necessary to obtain one or more bottles (plus or minus 2 l) from the laboratory. Depending on the type of test to perform, certain substances can find their way beforehand. It is important to leave as is and do not handle them. The first urine of the day is normally in the toilet. Subsequently, it is necessary to urinate every time in the bottle for the next 24 hours. It is essential to urinate in the bottle one last time at the end of 24 hours and filled it back to the lab.

In order to analyze your blood, a blood sample must be collected. Nothing is faster than a blood test! All you need to do is to visit a medical laboratory; making sure that you respect your doctor’s recommendations (for example, you may be ask to have an empty stomach). Once there, a nurse will collect a few centilitres of your blood according to a standardised technique: after placing an elastic around your arm (to make your veins swell), a needle will be inserted into your inside arm following strict disinfection protocols. The collected blood is placed into test tubes on which your name is inscribed. The number of test tubes depends on the range and type of tests required. After your blood test, you will be asked to press on your arm with a compress for a few minutes and you will naturally stop bleeding. Special equipment is used for infants (small catheter) to facilitate sample collection. However, please contact your medical laboratory first to check that their equipment and staff can collect blood from infants.

|A blood test may be required to further refine a diagnostic and to clarify the internal systems that are affected.|
|A blood test may be requested to monitor and control a chronic disease such as diabetes, hepatitis, or kidney or hepatic insufficiencies. Tests carried out will just be for this particular disease.|
HOW MUCH DOES IT COST?
