The diagnostic value of maternal pregnancy-specific beta 1-glycoprotein in threatened abortion

208 serum SP1 measurements have been made in 124 women admitted at the 8th to 20th gestational week for the treatment of threatened abortion. Pregnancy ended in abortion in 85,6 p.c. of the cases with pathological serum levels, while only 16,9 p.c. of the women with normal serum concentration aborted. The results demonstrate the prognostic value of serum SP1 estimations in early pregnancy.
