For example, for an appointment at 8:30 am with an empty stomach, you must have stopped eating and drinking (water allowed in small quantities) at 8:30 p.m.

In order not to distort the result, unless otherwise indicated by the Biologist, certain analyses must only be done on an empty stomach: Glycemia, Lipid profile (Cholesterol and fractions, Triglycerides), Electrophoresis of proteins, Cortisol, ACTH, Uric acid, Calcitonin, Iron…

In this case, it is possible to drink a glass of water in the morning and it is recommended to have a light meal the night before.

Certain analyses do not have to be done on an empty stomach (TP/INR, NFS, BHCG, blood tests for viruses, allergens, etc.). However, they must be taken between meals (3 hours after eating), while avoiding butter, milk, cream, fat…

  • The date and time of collection,
  • the date and time of the last collection,
  • the dosage information, the reason for the prescription.

List of drugs concerned : Digoxin, Carbamazepine, Valproic acid, Phenobarbital, Lithium, Tacrolimus, Ciclosporin…

A minor cannot come to the laboratory alone to have a specimen taken, except for analyses concerning an abortion or related to contraception or for STD testing (Sexually Transmitted Disease), apart from these exceptions, the minor must imperatively present a prescription. No specimen sample will be taken from minors without their approval.

Under no circumstances will the results be given to the minor.


Note that the minor patient can exercise his right to secrecy about his state of health, the results will therefore be communicated to the prescriber only.

For specimens to be taken from infants or young children, it is preferable to have them done at the laboratory.

A blood test is a mild medical procedure that can cause concern for both the child and his parents.

Our technicians are qualified to take these specimens..
