Annual Report on External Quality Assessment in Clinical Chemistry in Korea (2003) / 임상검사와정도관리

ABSTRACT

Ten trials of external quality assessment for Clinical Chemistry in general chemistry and blood gas were performed in 2003. All the control materials were sent in specifically-made boxes at the same time. The response rates were 90.3% in general chemistry and 91.8% in blood gas. The items included sodium, potassium, chloride, BUN, glucose, calcium, phosphorus, uric acid, creatinine, bilirubin, total protein, albumin, total cholesterol, triglyceride, AST, ALT, ALP, LD and GGT in general chemistry and pH, pCO2 and pO2 in blood gas. Compared with the previous year (2002), the methods of analysis are not changed much and the coefficient of variation and VIS scores of general chemistry items are decreased.
