Data are presented to show that human chorionic gonadotropin (hCG) in urine can be detected early in pregnancy by simple immunoassays performed prior to or around the time of the expected but missed menstrual period. Differences between the use of simple immunoassays with urine and radioimmunoassays and radioreceptor assays with serum are discussed.
数据表明，在预期月经该来却没来之前或前后进行简单免疫测定，可在妊娠早期检测出尿中的人绒毛膜促性腺激素（hCG）。本文还讨论了尿液简单免疫测定与放射免疫测定以及血清放射受体测定之间的差异。
