【摘要】 HCG酶免疫定性测定法特异性强,不受生理性LH水平变化(绝经后及月经中期)的干扰。143个尿标本测定无假阳性及假阴性结果;而胶乳试验有假阴性存在。其中2O例曾行血清HCG放免法测定与本法对比结果一致。其敏感性是胶乳试验的100倍,适用于极早期妊娠的诊断,宫外孕的鉴别及估价滋养细胞肿瘤的疗效。该法操作简便,无需特殊设备,易于推广。更多还原

【Abstract】 Enzyme immunoassay for the qualitative determination of HCG is highly specific. Physiologic changes in the plasma levels of LH such as postmenopause and midcycle peak did not interfere in this assay. Neither false positive nor false negative result were demonstrated in 143 urine samples measured by this method whereas one false negative was found in the same group determined by latex agglutination technique. RIA of HCG in serum has been carried out on 20 eases, the consistent results were obtained as compared with the present method. It is proved that the new technique is 100 times sensitive than latex agglutination test. It is suitable for diagnosis of early pregnancy and for differential diagnosis of ectopic pregnancy. It can also be used to evaluate the therapeutic result of trophoblastic tumor. The enzyme immunoassay method is simple and needs no special equipment, thus making its application more practical.更多还原
