Abstract
Histocompatibility laboratories perform the biological analyses linked related to organ transplant, hematopoietic stem cells transplant, some immune dysfunction diseases and immuno-allergy after therapeutic treatment. Most of these analyses are prospectively or retrospectively performed on sera and DNA. The Société Francophone d'Histocompatibilité et d'Immunogénétique (SFHI) has made some recommendations in order to define storage conditions and storage lifetime of the samples required in a histocompatibility laboratory. These recommendations have been drawn up by a working group of ten biologists. They have been established on literature review and data from method validation, which has been already performed within French laboratories (collected through a national questionnaire sent to participant laboratories). The recommendations made by the SFHI for the storage of samples for immunogenetics analyses facilitate the harmonization of practices among histocompatibility laboratories.
