Investigation of detection methods for aggregation function of platelets / 国际检验医学杂志

ABSTRACT

Objective To adopt 5 kinds of platelets aggregation function analyzer to explore and study the reliable method for detecting the platelets aggregation function and accurate parameters .Methods The platelets aggregation function in the control group and the single clopidogrel group was simultaneously detected by utilizing the ADP induced light turbidimetric platelet aggre‐gation analyzer (LTA) test ,flow cytometry for PAC‐1(receptor of Fg ,Ca2+ ,GPⅡb/Ⅲa forming complex) and CD62p(P selectin) activation percentage detection test ,Innova PL‐11 for platelets analysis test ,VerifyNow anti‐platelet therapy monitoring system and thrombelastogram(TEG) .Results (1)The 6‐parameter differences of ADP% ,PAC‐1 and CD62p receptor activation percentage ac‐tivated by ADP ,MAR% ,INHI% ,ADP induced MA value(mm) detected by TEG had statistical differences between the control group and the case group(P0 .05) .(2)ADP% was positively correlated with (100‐INHI)% ,MAR% ,ADP activated CD62p and PAC‐1 receptor activation percentage(r=0 .565 ,0 .939 ,0 .769 ,0 .583 ,P<0 .05 );while which had no correlation with ADP induced platelets aggregation value(% Agg) detected by TEG(r=0 .794 ,0 .715 ,0 .889) .Conclusion (1)Clopidogre has the anti‐platelets effect .(2)LTA is easily operating ,cheap and stable in detection results ,has high popularizing rate in hospitals and is the first option method for clinically monitoring the platelets aggregation function .
