虽然麻疹通常可根据其典型的临床表现作出诊断,但是,单凭临床表现未必能排除其他疾病.目前,除白细胞数减少外,尚无广泛适于直接诊断麻疹感染的实验室方法.为了查明血清乳酸脱氢酶(LDH; EC1.1.1.27)活性升高是否与麻疹感染相关,作者用时序多通道连续流动分析器测定了75例麻疹患儿和105例对照病人(包括支气管炎23人,支气管炎伴胃肠炎 Although measles usually can be diagnosed on the basis of their typical clinical manifestations, clinical manifestations alone may not rule out other diseases, and there is currently no widely available laboratory method for the direct diagnosis of measles infection other than a reduction in white blood cell count. Serum lactate dehydrogenase (LDH; EC1.1.1.27) activity is associated with measles infection, the authors used a time-series multichannel continuous flow analyzer measured 75 cases of measles and 105 cases of control patients (including 23 bronchitis , Bronchitis with gastroenteritis
