Evaluate fetal distress and placental function in the management of patients facing complications such as pre-eclampsia, fetal growth retardation, diabetes, Rh immunization, choriocarcinoma, and hydatidiform mole. May be elevated in hydrops fetalis in the presence of a dying fetus. May be low in the presence of a living anencephalic fetus.
The placenta converts DHEA-S produced by the fetal adrenals to Estriol and other estrogens. Estriol is useful in assessing the fetal adrenals and placenta during pregnancy. More commonly, Estriol is one of the maternal serum biochemical markers used to screen for common chromosomal trisomies, especially Down syndrome.
