[Experimental analysis and countermeasures for EDTA-dependent Pseudothrombocytopenia].

The purpose of this study was to investigate the incidence of clinically common EDTA-dependent pseudo-thrombocytopenia (EDTA-PTCP) and methols for treating this diseese. A total of 1326 cases of thrombocytopenia found at blood routine examination were amalyzed anong 71 535 patients hospitalized in our hospital from January 2010 to May 2013, and 87 cases of PTCP caused EDTA-K anticoagulant were analyzed again by using sodium citrate auticoagulant, at the same time the platelet formation distribution was observed by microscopy of smear with Wright-Giemsa staining. The results showed that the platelet count detected by using EDTA-K anticoagulant in 87 cases was (56 ± 27)×10(9)/L, while the platelet count detected by using sodium citrate was (185 ± 39)×10(9)/L (t = 1.
