[Do pregnancy proteins have prospective significance? (SP-1, HPL and PP-5)]

Concentrations of pregnancy proteins were determined in blood of 219 pregnant women in 20th week of gestation. Pregnancy-specific beta 1-glycoprotein SP-1, human placental lactogen (hPL) and placental protein 5 (PP-5) were tested. In contrast with results of other authors there were no differences between the normal group of patients and those with complications during gestation, such as prematurity and foetal retardation. Thus measurement of blood concentration of proteins mentioned above in 20th week is not of prognostic relevance for gestation.
