The role of clinical chemistry in the diagnostic process has been enhanced by the evolution of better instrumentation and analytical techniques. The quality of some laboratory tests, however, has not kept pace with these advances. I present three examples--serum iron, serum lipase, and nonisotopic immunoassays--assays where some currently used methodologies are highly flawed. Causes for the less than optimal performance of some clinical laboratories are discussed.
更好的仪器设备和分析技术的发展提升了临床化学在诊断过程中的作用。然而，一些实验室检测的质量却未能跟上这些进步。我给出三个例子——血清铁、血清脂肪酶和非同位素免疫分析——目前一些使用的方法存在严重缺陷。文中讨论了一些临床实验室表现欠佳的原因。
