Measurement of AHSP concentration: Pseudonymization and identification of research samples EDTA tube of 4 mL for patients over 15 and a half years old, and 2 EDTA tubes of 2 mL for children aged 3 to 15 and a half years, totaling 4 mL) by Team 4 according to the procedure in force at the URC.
The 4 mL research sample will then be divided into 1 mL fractions by a technician in the laboratory and stored at -80°C in the medical biology laboratory.
