Clinical Significance
This test detects and quantifies the percent of fetal cells in the mother's circulation. It is used to determine dosage of Rh immune globin (Rho-GAM) required to prevent Rh sensitization of an Rh negative mother. It is also used as an aid in identifying fetal-maternal hemorrhage to evaluate possible trauma to the fetus.
