[Is prognostic information obtainable from serum PZ level with imminent abortion? (author's transl)]

Reported in this paper are 359 abortion patients and 550 women with normal pregnancy from whom serum PZ (pregnancy zone protein), SP3, PAG, was determined, between 1974 and 1979. Serum PZ failed to enable any safe prognostic assessment of endangerment to early pregnancy. Evaluable diagnostic information was found to be not obtainable before the tenth week of pregnancy. Any drop of data below the critical limit of 200 mg/l must be taken to indicate with high probability that pregnancy is no longer intact.
