Pregnancy-associated globulin body fluids of pregnant women.

Abstract

Pregnancy-associated globulin (PAG) in saliva, urine and amniotic fluid was investigated just before and after delivery by Ouchterlony's method and im munoelectrosyneresis.In saliva, the incidence was more than 60%; 12 out of 18 samples by immunoelectrosyneresis and 11 out of 18 by Ouchterlony's method. In urine, 8 (33%) and 6 (25%) out of 24 samples were positive by immunoelectro syneresis and Ouchterlony's method, respectively.In amniotic fluid, only 3 out of 21 were positive by Ouchterlony's method, but 19 out of 21 samples (91%) were positive by immunoelectrosyneresis.Of 12 pregnant women in whom serum, saliva, urine and amniotic fluid were tested by immunoeleetrosyneresis, four showed positive reaction in the above four samples and 11 in three samples except urine.pregnancy-associated globulin; saliva; urine; amniotic fluid
