임상화학검사 신빙도조사 결과보고 (2007)

Abstract

Background: Six trials with 3 samples for each of external quality assessment for general chemistry and blood gas were performed in 2007. All the control materials were sent in specifically-made boxes at the same time. The response rates were 92.0% in general chemistry and 95.5% 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 (2006), the methods of analysis were slightly changed and the coefficient of variation and VIS scores of general chemistry items were not significantly changed.
