Gender prediction testing can be carried out with blood or with urine. It is important that whichever of the two you opt for, you ensure that they are actually DNA tests and

not any other DIY test that provides you with instant results at home. A competent laboratory should be undertaking the analysis of your sample to determine the sex of your child by means of a DNA test.

Urine DNA baby gender testing to determine whether you will have a baby boy or baby girl is pretty accurate, although a more recent and revolutionary method than blood. You are in fact likely to stumble across more companies offering the test with blood than with urine. The gender test using a sample of maternal urine offers a very high success rate of around 99%.

With blood, a gender prediction test is still over 95% accurate in determining the sex of the child and the test can be carried out in the easy and comfort of your own home. However, one of the major disadvantages of some baby gender tests is that they require blood and are thus, invasive tests. A home kit will be sent out to the address you specify which will enable you to complete the sampling for the baby gender test.

Using Maternal Urine and Maternal Blood Samples

To be able to carry out either baby gender test you will need to know how far along in the pregnancy you have arrived. With either test, you should not go ahead unless you are at least 9 weeks pregnant. Knowing the time of conception is important for baby sex prediction and can easily be done if you have regular periods. The baby gender test with blood can be done as early as the tenth week from the first day of the last menstrual period. If you have irregular periods, knowing when you released an egg is harder. You could try and count backwards from the day you tested pregnant- this can give a fair idea of the time you conceived.

Both tests using blood or urine rely on identifying the male DNA in the maternal blood or maternal urine. The fetal DNA finds its way into the mother’s blood through the placenta (a point of exchange for nutrients and oxygen between the fetus and the mother). The blood will get filtered in the kidneys and the fetal DNA will pass out in the maternal urine. This means that sample, urine or blood, will provide fetal DNA in it.

Urine samples are also used in some other types of baby gender tests. These tests require the pregnant mother to urinate in a cup and wait for a change in colour; one colour indicates a boy and another a girl. These tests lack scientific backing; they claim to be able to detect male or female hormones in the mother’s urine. Gender prediction testing should be scientific. Make sure you pick the right company to do it.
