According to a new study, doctors may be able to use technology to tell whether you’re going to have a boy or a girl as early as seven weeks into your pregnancy. What’s most exciting about the prospect of this test is that it’s a simple blood test that’s non-invasive and tremendously accurate.

The researchers looked at 57 scientific studies of gender testing. The results suggested that a woman could know the sex of her baby as little as one to two weeks after she misses her period.

The accuracy statistics are impressive. At seven weeks of pregnancy, the test can analyze a mother’s blood for the presence of fetal DNA. When that DNA is analyzed, it can tell if the baby is female accurately more than 98 percent of the time. If it’s identified as male, accuracy drops only slightly at about 95 percent.

As pregnancy continues, the test actually becomes more accurate, as well.

This is a huge step. Today, women can typically only learn their baby’s sex via an ultrasound, and not until the 18th to the 20th week of pregnancy. Not only does it make things more convenient for parents, however, it can have some specific health implications.

For example, for families that are known to have disorders such as hemophilia that are linked to sex genetic information, it can help to reduce the amount of times that an invasive procedure might have to be performed.

That said, it’s not likely that this blood test will be done solely for gender identification. When there are health concerns where it can be of use to know the baby’s gender, it may be very useful. Generally speaking, there will need to be a medical reason for the test to be done.

So, what do you think? Setting aside the medical issues for a moment, would it be useful to know your baby’s gender earlier? Is 7 weeks of pregnancy too soon?
