Annual Report on External Quality Assessment in Clinical Chemistry in Korea (2009) / 임상검사와정도관리

Six trials with 3 samples for each trial for external quality assessment of general chemistry and blood gas were performed in 2009. All the control materials were sent in specifically-made boxes at the same time. The response rates were 87.5% in general chemistry and 89.3% 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 (2008), change of the methods of analysis was not remarkable. The peer group coefficient of variation and the VIS scores of general chemistry items were slightly improved.
