[The problem of prognostication in disturbed pregnancies (author's transl)]

A semiquantitative immunological GCG determination was carried out in the urines of 186 patients with the diagnosis abortus imminens. For prognosis of the further course of pregnancy the patients were subdivided into various groups according to the results of the HCG determination. In the group IV with primary positive immunological tests up to titres of 1:8 and higher with constant of even increasing titres in control test 87% of the patients were able to carry to a full term, only in 13% an abortus took place. In the group with the lowest and more over falling titres 100% abortus occurred. No conclusions as to the therapy are drawn on the basis of the here presented results.
