临床上曾应用血清和腹水中的乳酸脱氨酶、血清和腹水中白蛋白梯度、甘油三脂等测定以助对腹腔积液的诊断和鉴别诊断,但各有优缺点。近年来,有人报道测定腹水中纤维粘连蛋白(FN)以鉴别腹水的性质有较大实用价值。作者等于1988年以上海生物制品研究所提供的试剂,用比浊法对36例 Clinically, serum and ascites serum lactate deaminase, serum and ascites albumin gradient, triglyceride and other measurements to help diagnose and differential diagnosis of peritoneal effusion, but each has its own advantages and disadvantages. In recent years, it has been reported that the determination of ascites fibronectin (FN) to identify the nature of ascites has greater practical value. The author is equal to the reagents provided by the Shanghai Institute of Biological Products in 1988, with turbidimetric method of 36 cases
