There are some home urine kits which claim to be able to instantly tell you the sex of your unborn child. These tests generally require the first morning urine which is mixed with a solution provided in the kit. The test relies on detecting certain hormones which pass out with the maternal urine. The hormones react to the solution to produce a different colour depending if the baby is a boy or a girl. The accuracy or reliability of this test can never be compared to analytical testing in a laboratory in terms of accuracy. The actual accuracy levels have also been questioned.
