Fetal Blood Sampling

Fetal blood sampling is  a procedure  to remove a small amount of  blood from the fetus during  pregnancy. In the past, this procedure was used only during labor through the mother’s open cervix to test blood from the fetal scalp for oxygenation. The procedure is usually done by specialized trained  perinatologist, a doctor who specializes in the care of the fetus in high risk pregnancies. It is done as part of diagnosing fetal problems  at various times of pregnancy.
