Annual Report on External Quality Assesment in Hematology in Korea (2003) / 임상검사와정도관리

ABSTRACT

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.
