为探讨 CEA和 MGAgs对良恶性腹水的鉴别诊断价值 ,同期检测 30例良性腹水和2 7例恶性腹水中 CEA和 MGAgs的含量。结果显示 ,CEA和 MGAgs诊断恶性腹水的敏感性分别为 5 5 .6 %和 5 9.7% ,特异性为 10 0 %和 96 .7% ,准确度为 78.9%和 78.9%。联合检测的敏感性、特异性和准确度分别为 77.8%、96 .7%和 87.7%。 CEA和 MGAgs联合检测对良恶性腹水有较高鉴别诊断价值。 To investigate the value of CEA and MGAgs in the differential diagnosis of benign and malignant ascites, the levels of CEA and MGAgs in 30 benign ascites and 27 malignant ascites were measured in the same period. The results showed that the sensitivity of CEA and MGAgs in diagnosing malignant ascites was 55.6% and 59.7% respectively, the specificity was 100% and 96.7%, and the accuracy was 78.9% and 78.9%. The sensitivity, specificity, and accuracy of the combined tests were 77.8%, 96.7%, and 87.7%, respectively. The combined detection of CEA and MGAgs has high differential diagnostic value for benign and malignant ascites.
