title: Detection of pregnancy specific protein SP-1 by enzyme immunoassay in early pregnancy.
abstract: Levels of pregnancy specific beta 1-glycoprotein (SP-1) were measured serially in serum by using enzyme immunoassay in 10 women after ovulation detected by LH-surge. Serum SP-1 levels rose at 13 and 20 days after the LH-surge.
