应用免疫学和生化学的检测技术,作肺部良恶性疾病的鉴别诊断,仍处在探索阶段。国内报道用于诊断肺癌的检测方法较多。鉴于酚试剂法在所有文献报道中对肺癌的阳性检出率(96.6％)较其它方法为高,我们选用此法,首先从电泳行为、分子量、紫外吸收光谱、在50％饱和盐、PH The use of immunological and biochemical detection techniques for the differential diagnosis of benign and malignant lung disease is still at an exploratory stage. Domestic reports are used to diagnose lung cancer. Since the positive detection rate of lung cancer by the phenol reagent method was 96.6% in all literature reports compared with other methods, we chose this method, firstly from the electrophoretic behavior, molecular weight, UV absorption spectrum, at 50% saturated salt, PH
