【摘要】 目的寻找对结核性腹水高敏感、高特异而又简单的检查方法。方法采用改良的Ｍａｒｔｉｎｅｃｋ法和ＥＬＩＳＡ法对５０例结核性腹水腺苷脱氨酶（ＡＤＡ）和结核抗体水平进行了检测，并以４５例恶性腹水和３０例肝硬化腹水作对照。结果结核性腹水ＡＤＡ和结核抗体水平显著高于对照组（Ｐ＜００１）。以ＡＤＡ＞３０Ｕ／Ｌ作为阳性标准，其对结核性腹水的敏感性为１００％，特异性为９８６％，准确性为９９２％；结核抗体对结核性腹水的敏感性为９０％，特异性为９３３％，准确性为９２％。结论ＡＤＡ和结核抗体对诊断结核性腹水均有重要价值。在使用抗结核药特别是在并用激素治疗后，腹水ＡＤＡ及结核抗体水平会随之下降，故应在停药１周后检测并动态观察二者的变化。更多还原

【Abstract】 Objective\ To seek better diagnostic tests for tuberculous ascites. Methods\ Adenosine deaminase (ADA) and anti-TB in ascites were tested by modified Martineck’s method and ELISA in 50 cases of tuberculous ascites,45 cases of carcinous ascites and 30 cases of cirrhotic ascites,respectively. Results\ The level of ADA and anti-TB in ascites was remarkably higher in tuberculous ascites than that in carcinous ascites and cirrhotic ascites (P<0.01).When ADA>30U/L and positive anti-TB were present,their sensitivity,specificity and accuracy in diagnosis of tuberculous ascites are 100%,98.6%,99.2% and 90%,93.3%,92%,respectively. Conclusion\ The tests of ADA and anti-TB in ascites are very important in diagnosis of tuberculous ascites.更多还原
