Analysis of characters and biochemical profiles of 27 cases with EDTA-Dependent Pseudothrombocytopenia / 国际检验医学杂志

ABSTRACT

Objective To analyze the characters about anticoagulation EDTA on the platelet aggregation ,and discuss the risk factors about EDTA‐PTCP by analyzing the biochemical parameters .Methods 30 700 EDTA‐K3 blood samples were collected from January 2014 to August 2015 .WBC was performed using Sysmex XN‐3000 and 27cases were identified of EDTA‐PTCP .The blood samples of 27 subjects were recollected and WBC was repeated using EDTA‐K3 and sodium citrate blood ,respectively .Manual platelet counting and smear microscope examination on periphery blood were also performed .Biochemical parameters of 27 subjects with EDTA‐PTCP were compared with 50 randomly selected non EDTA‐PTCP controls .Results Platelet counts in citrated blood were significantly higher than EDTA blood ,the difference was statistically significant(P0 .05) .ALT ,Glu and TG in patients with EDTA‐PTCP were significantly higher than normal people ,but HDL was significantly lower than control group ,the difference was statistically significant(P<0 .05) .Conclusion EDTA‐dependent pseudo‐thrombocytopenia varies from people with different disease or using different medicine .It may be relative to hyperglycemia and hy‐perlipidemia .Another approach for rectifying ,changing anticoagulant or manual platelet counting is a better way lead to correctly di‐agnose when EDTA‐PTCP occurred .
