选择123例行hCG定量测定患者为研究对象,排除不孕、肿瘤及最后诊断不明者23例,研究对象为100例。这些患者大多数系怀疑异位妊娠或其它异常妊娠而行hCG测定,其中93例有腹痛和/或阴道异常出血。取血清标本置于-20℃待测。hCG用荧光免疫法测定,其敏感度为2mIU/ml,孕酮及E_2用增强发光免疫法测定,其敏感度孕酮为0.6ng/ml、E_2为37.4pg/ml,甲胎蛋白(AFP)用竞争放射免疫法测定,其敏感度为1ng/ml。 根据最后诊断将研究对象分为4组,即正常妊娠组、异位妊娠组、自然流产组及非妊娠组。4组患者的年龄、足月产、早产、异位妊娠,自然流产、引产次数均无显著差异;三组妊娠组的孕周亦无明显差异。临床病史显示虽然所有患者均主诉腹
123 cases of hCG quantitative determination of patients as the research object, excluding infertility, cancer and the final diagnosis of unknown persons in 23 cases, the study of 100 cases. Most of these patients were suspected of ectopic pregnancy or other abnormal pregnancy hCG determination, of which 93 cases of abdominal pain and / or vaginal bleeding. Serum samples were placed at -20 ℃ to be tested. The sensitivity of hCG was 2mIU / ml and the level of progesterone and E_2 was 0.6ng / ml, E_2 was 37.4pg / ml, AFP and AFP were respectively measured by fluorescence immunoassay. The competitive radioimmunoassay, the sensitivity of 1ng / ml. According to the final diagnosis, the subjects were divided into 4 groups: normal pregnancy group, ectopic pregnancy group, spontaneous abortion group and non-pregnant group. There was no significant difference in the age, full-term, premature, ectopic pregnancy, spontaneous abortion and induction of labor among the 4 groups. There was no significant difference in gestational age among the three groups. Clinical history showed that although all patients complained of abdominal distention
