Abstract: Objective To explore whether storage time and temperature influence the measurement of blood clotting functional parameter,in order to ensure accuracy of result.Methods 60 anticoagulated blood samples were selected.The levels of APTT,PT,TT and FIB were detected immediately after separated plasma,at 1 h,2h,and 4h after keeping at room temperature,at 4h,12h,24h after keeping at-4℃.Part of anticoagulated blood samples were separated plasma and detected 2h after keeping at room temperature.Results Compared to measurement for immediately separated plasma,APTT,PT,TT and FIB showed no differences for 1 h,2h after keeping at room temperature and 4h,12h,24h after keeping at-4℃.But the result for 4h after keeping at room temperature showed bad accuracy.Conclusion In the measurement of coagulation indices,after collecting blood sample,separating plasma should be conducted as soon as possible.The separated plasma should be measured within 2h after keeping at room temperature and 24h after keeping at-4℃.
