RESUMEN
Four trials of external quality assessment in diagnostic hematology were performed in 2007 with average 722 participating laboratories in Korea. We performed quality assessment for white blood cell count, hemoglobin, hematocrit, red blood cell count, platelet count, blood cell morphology, prothrombin time and activated partial thromboplastin time. The response rate was more than 95.2%. The coefficients of variation in hemoglobin, hematocrit and RBC were stable but variable in platelet count and WBC count according to measuring cell counters. Test results of blood cell morphology showed variation among various cell morphologies.

Four trials of external quality assessment in diagnostic hematology were performed in 2005 with about 500 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. The response rate was more than 97%. The coefficients of variation in hemoglobin and RBC number was stable but variable in platelet number and WBC number according to measuring cell counts. Test results showed wide variation according to measuring machine and reagents.

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.

Four trials of external quality assessment in diagnostic hematology were performed in 2003 with about 430 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 95%. The performance of quality assessment appeared to be gradually improved year by year.
