Abstract

Objective To explore the effects of activated time on APTT test after added Micro silica and find the optimal activated time range.Methods APTT were measured by semiautomatic thrombo machine in platelet-poor plasma(PPP) in 73 patients and healthy subject,and activated time were1,3,7,12,15 minutes,respectively.The evaluation of data use t-test by comparing with 3-minute group.Results The activated partial thromboplastin time of 1-minute group was much longer than that of the 3-minute group and the result of 15 minute group was to the contrary..There was no significant difference between the results of other groups.Conclusion Activated time must be longer than 3 minutes and shorter than 12 minutes in APTT test by semiautomatic machine or manual operation.
