Blood Test Can Tell Fetus's Sex at Just 7 Weeks

Wednesday, August 10, 2011 - 14:30 in Health & Medicine

A simple blood test can determine a baby's gender as early as seven weeks into pregnancy, a new study says - far earlier and far less invasive than other options. The test could conceivably help parents who are worried about gender-related diseases, but it could also allow people to wade into the morally murky waters of sex selection. The test analyzes fetal DNA found in a mother's blood, according to a report in the New York Times. If a Y chromosome is present, the mother is having a boy; if it's not, it probably means the fetus is female (but could also mean that blood sample doesn't contain fetal DNA). Researchers examined 57 studies of fetal DNA tests, spanning some 6,500 pregnancies. The results were published in the Journal of the American Medical Association.
