Some prenatal gender tests that use mom's blood are very accurate at determining baby's sex, a new study finds. But curious parents-to-be should be wary of online marketers that claim to be able to figure out fetal gender using just a woman's urine.
New research to be published Aug. 10 in the Journal of the American Medical Association finds that after seven weeks into a pregnancy, tests that analyze mom's blood for fetal DNA can correctly identify-a male fetus-95.4 percent of the time and a female fetus 98.6 percent of the time on average. In comparison, tests that analyzed DNA from urine instead of blood were only accurate 41 percent of the time, said study researcher Diana Bianchi, a reproductive geneticist at Tufts University School of Medicine.
"It was worse than flipping a coin," Bianchi told LiveScience."
