Abstract:
Four trials of external quality assessment in diagnostic hematology were performed in 2004 with about 440 participating laboratories in Korea. We performed quality assessment for white blood cell count, hemoglobin, red blood cell count, platelet count, white cell differential count, red blood cell morphology and coagulation test. The response rate was more than 96%. The coefficients of variation in hemoglobin and RBC number was stable but variable in platelet number and WBC number according to measuring cell counts. Blood coagulation study was performed twice. Test results show wide variation according to measuring machine and reagents.
