Why the study?
Does storage on ice or at room temperature for 4 hours affect the stability of routine and specialized coagulation assays compared to immediate centrifugation?
Does storage on ice or at room temperature for 4 hours affect the stability of routine and specialized coagulation assays compared to immediate centrifugation?
Whole blood specimens for most coagulation assays are stable for 4 hours at room temperature, and transport on ice does not provide substantial benefit and may cause clinically significant changes in some factors.
No takes yet. Share an insight, caveat, or question.
Room-temperature transport suffices for most coagulation assays at 4 h; leaves open factor VIII handling pending larger validation.
