[The clinical significance of the immunoenzyme determination of trophoblastic beta 1-glycoprotein].
The authors analyze the diagnostic potentialities of measurements of trophoblastic beta 1-glycoprotein (TBG) in trophoblastic diseases, in normal pregnancy, threatened abortion, and ectopic pregnancy. Two laboratory tests for the diagnosis of pregnancy are compared: gravidodiagnosticum test and enzyme immunoassay of TBG. The findings have demonstrated a number of important advantages of enzyme immunoassay of the serum TBG. Measurements of urinary TBG are useless for the early diagnosis of pregnancy, because the protein level is low and does not correlate with a gestation period.
