Do pregnant women benefit from hemoglobinopathy carrier detection?

A 45% sample of all pregnancies in Rochester, N.Y. over a five-year period showed that 4.2% of pregnant women had a hemoglobinopathy. Sixty-six percent of these women did not know they had such an abnormality, and 80% did not understand its reproductive significance. Sixty-eight percent of women informed they were positive came for counseling. Fifty-seven percent of counseled women had the baby's father tested. Forty-seven percent of couples at risk offered amniocentesis wanted it. (table; see text) A woman was more likely to want her partner tested if she had a more thorough knowledge of the disease or viewed having an affected child as more burdensome. The partner was more likely to come for testing if the couple were living together than if living apart. Prenatal hemoglobinopathy screening is accepted by providers and pregnant women, at least when expert services are provided at no charge to either. Women and couples use the information provided to pursue their reproductive goals.
