[ XXXX beta chorionic gonadotropin in the early diagnosis of extrauterine pregnancy].

@entity1 @entity1465
In 1979 and 1980, at the University Hospital Department of Gynecology and Obstetrics, 115 @entity1 with extrauterine pregnancy were surgically treated. In 26 @entity1 the value of the radioimmunologic determination of @entity1465 in the serum was analysed. Along with it, also other clinicodiagnostic procedures (immunochemical test for pregnancy, culdocentesis, curettage) wire carried out. Not in a single case of extrauterine pregnancy in which the serum beta @entity1465 level was determined, was the result falsely negative. The immunochemical test for pregnancy was falsely negative in 32.6% and the result of culdocentesis was falsely negative in 13.6% of the @entity1 examined. In @entity1 with negative culdocentesis laparoscopy was performed (10.4%), showing ectopic pregnancy. In the course of extrauterine pregnancy the elimination of beta @entity1465 was significatly reduced in relation to its level in normal pregnancy. The concentration of beta @entity1465 in the observed @entity1 with extrauterine pregnancy ranged from 27 to 3924 IU/L. On the basis of a low beta @entity1465 concentration in the serum it is possible to determine with much certainty that pregnancy is not quite normal. Of great help is the observation of changes in the elimination of this hormone over a short period of time. A timely diagnosis of extrauterine pregnancy improves prognosis of future fertility.
