임상화학검사 신빙도 조사 결과보고 (2006)

Abstract

Six trials with 3 samples for each of external quality assessment for general chemistry and blood gas were performed in 2006. All the control materials were sent in specifically-made boxes at the same time. The response rates were 90.7% in general chemistry and 88.7% 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(2004 or 2005), the methods of analysis are changed and the coefficient of variation and VIS scores of general chemistry items are slightly increased.
