[Stability of hemostatic parameters in whole blood, fresh plasma, and frozen plasma: literature review and recommendations from the French Society of Thrombosis and Hemostasis (SFTH)].

Pre-analytical management of samples in hemostasis is essential for the correct assessment of parameters. Although there is extensive literature on this subject, the Working Group of the French Society of Thrombosis and Hemostasis deemed it necessary to conduct a review of the literature and propose recommendations for the stability of samples before hemostasis assays. These recommendations are based on a literature review of publications from 1997 to 2024, initially analyzed by a working group of 6 experts and then reviewed by 13 other biologists. The various conditions are summarized in tables that will assist hemostasis laboratories in managing samples and -transporting specimens. Furthermore, since some conditions clearly have not been the subject of evaluation, this review opens new fields of investigation.
