A glycoprotein with the electrophoretic mobility of a beta-1 globulin. It is produced by the placental trophoblast and secreted into the maternal bloodstream during pregnancy. It can be detected 18 days after ovulation and its concentration in plasma rises steadily until, at the end of gestation, it reaches 200 mg/ml. It has been proposed as a measure of placental function for fertility control and is a candidate for an early pregnancy test.
