Human Placental Lactogen
- HCS (Human Chorionic Somatomammotropin)
Lactogen is a hormone released by the placenta during pregnancy, with levels peaking around 35 weeks' gestation. hPL blood levels are an indication of how well the placenta is functioning, and normal levels have been identified for set intervals throughout pregnancy. An indication of placental failure is when hPL levels are lower than normal, which can lead to reduced growth in the unborn baby, intrauterine death of the unborn baby, or the possibility of a miscarriage. High hPL levels are seen in pregnant women who are carrying multiple babies, or women with diabetes mellitus (DM). hPL levels are monitored in pregnant women who have complications due to eclampsia (high blood pressure), diabetes mellitus (DM), who are past their due date, who are carrying an Rh incompatible baby, or to determine whether the placenta is functioning properly.
