[SP-1 in normal and complicated early pregnancy. Diagnosis by enzyme immunoassay].

Pregnancy specific glycoprotein SP-1 was measured by enzyme immunoassay Enzygnost in patients with diagnosis of haemorrhage in early pregnancy. Results were compared with a normal range between 6.-22. week of gestation (n = 268) and were analysed for their predictive value in determining prognosis. 24 of 27 cases with levels below the normal range had an abortion (88,9%) while 28 of 31 women with continuing pregnancies had levels within normal range (90,3%).
