Expecting moms can determine whether they're carrying a boy or a girl as early as 10 weeks after conception, according to makers of an over-the-counter gender prediction test.

With IntelliGender's home gender prediction test, a urine specimen turns orange if it's a girl. Green is for boys.

IntelliGender, the Plano, Texas, creator of the "Boy or Girl Gender Prediction Test," says scientists isolated certain hormones that when combined with a "proprietary mix of chemicals" react differently if a woman is carrying a boy or a girl.

It claims that within 10 minutes of taking the urine test, a woman will be able to tell her baby's gender. The specimen will turn green if it's a boy, and orange if it's a girl.

IntelliGender would not say what hormones or chemicals it uses it in its test because of a pending patent.

"Most parents have a great degree of curiosity to find out if they're having a boy or a girl, and it can be so excruciating to wait until the 20-week sonogram to find out," IntelliGender co-founder Rebecca Griffin said. "But the test was never meant to be a diagnostic tool. We don't claim 100 percent accuracy."
