Boy or girl? Simple blood test in the first trimester predicts fetal gender

Boy or girl? Simple blood test in the first trimester predicts fetal gender: New findings could lead to a non-invasive test allowing expecting mothers to learn the sex of their baby as early as the first trimester. Specifically, researchers discovered that various ratios of two enzymes (DYS14/GAPDH), which can be extracted from a pregnant mother's blood, indicate if the baby will be a boy or a girl. Such a test would be the first of its kind.
