New Blood Test Reveals the Gender of your Baby at Seven Weeks

Aug 10, 2011
The scientists have developed a new technology that can help parents get to know the gender of the unborn baby as early as seven weeks of pregnancy.

The novel method analyzes cell-free fetal DNA that is present in the blood of a pregnant woman. The simple blood test can reveal whether you have a boy or a girl just a week or two after a woman misses her periods. Typically, a woman can find out about the gender of her baby during ultrasound procedure at 18-20 weeks.

Scientists say that this test is primarily aimed for parents, who are concerned about genetic diseases that affect certain gender. They also can be useful for women at risk of having a baby with genital malformations and need treatment, as they might avoid it in case they carry a baby of another gender.

While these early cell-free fetal DNA tests are already common in Europe, they were not available from doctors in USA. There are some companies that offer this service online, promising to predict the gender of the unborn baby with 95 to 99 percent of accuracy at 5 to7 weeks of pregnancy.
