EDTA 항응고제에 의한 위혈소판 감소증 2 예 = Two Case of Pseudothrombocytopenia Due to EDT A Anticoagulants

다국어 초록 (Multilingual Abstract)

EDTA 2K, one of the some kinds of anti-coagulants used for hematology tests, is most frequently used for CBC tests since it does not affect the size and blood cell morphology. Nowadays automatic cell counters are widely supplied to many hospitals, big or small, and are commonly used. As a result, platelet test has become a routine CBC ,test. In fact, patient blood sample with a normal platelet sometimes show a much decreased number of platelet due to platelet aggregation and platelet satellism affected by EDT A anti-coagulant which is so called pseudothrombocytopenia. If any further confirmation tests are not done for such patient, then it can lead misdiagnosis and unnecessary medical care such as bone marrow aspiration, various platelet function test and transfusion for platelet concentrated and it can raise a problem later on. We found that pseudothrombocytopenia from two patient blood samples showing decrease of platelet and report hereunder with brief literatures.
