A comparison between new urine and serum enzyme immunoassay techniques and existing serum radioimmunoassay techniques for the detection of HCG in the diagnosis of ectopic and early intrauterine pregnancy was undertaken. Urine HCG estimations by enzyme immunoassay were not found to be adequate for the exclusion of ectopic pregnancy due to a false negative rate of 12.5% (2 of 16 patients). Serum HCG estimations by enzyme immunoassay were found to compare favourably with radioimmunoassay techniques in the detection of HCG in both ectopic and early intrauterine pregnancy.
对新型尿液和血清酶免疫测定技术与现有的血清放射免疫测定技术进行了比较，以检测人绒毛膜促性腺激素（HCG）用于异位妊娠和早期宫内妊娠的诊断。通过酶免疫测定法进行的尿液HCG测定被发现不足以排除异位妊娠，因为假阴性率为12.5%（16例患者中有2例）。发现在检测异位妊娠和早期宫内妊娠的HCG方面，通过酶免疫测定法进行的血清HCG测定与放射免疫测定技术相比具有优势。
