Annual Report on External Quality Assesment in Hematology in Korea (2002) / 임상검사와정도관리

ABSTRACT

Four trials of external quality assessment in diagnostic hematology were performed in 2002 with about 400 participating laboratories in Korea. We performed quality assessment for white blood cell count, hemoglobin, red blood cell count, platelet count, reticulocyte count, white cell differential count, and red blood cell morphology test. The response rate was more than 90%. The performance of quality assessment appeared to be gradually improved year by year.
