对４６例滋养细胞疾病患者尿标本２７５份进行尿促性腺激素片段（ＵＧＦ）测定，并自身对照收集同期血标本２７５份，测定绒毛膜促性腺激素（ｈＣＧ），并进行比较。另选１２例健康非妊娠妇女为对照组。结果，滋养细胞疾病患者尿ＵＧＦ阳性串（＞０．２μｇ／Ｌ）为６４．０％，血清ｈＣＧ阳性率（＞２０μｇ／Ｌ）为６６．５％，两者差异无显著性（Ｐ＞０．１）。血清ｈＣＧ阴性患者中，尿ＵＧＦ阳性者５７．６％。提示在滋养细胞疾病患者血ｈＣＧ呈高值时，尿ＵＧＦ阳性率亦高，测定意义不大。而血ｈＣＧ呈低值、ｈＣＧ阴性时，尿ＵＧＦ仍有一定的检出率。对照组１２例无假阳性。
A total of 275 urine samples from 46 patients with trophoblastic disease were tested for urinary gonadotrophin (UGF), and 275 blood samples were collected from their controls. The levels of hCG were measured and compared. Another 12 healthy non-pregnant women as the control group. The results showed that urinary UGF positive (> 0.2μg / L) in trophoblastic disease was 64.0% and serum hCG positive rate (> 20μg / L) was 66.5%, with no significant difference (P> 0 .1). Serum hCG-negative patients, urinary UGF-positive 57.6%. Tip of trophoblastic disease in patients with high blood hCG values, urine UGF positive rate is also high, the determination of little significance. The blood hCG was low, hCG negative, urinary UGF still have a certain detection rate. The control group of 12 cases without false positive.
