How is it done?

The fetal sex determination test is carried out on a sample of about 5 ml of the mother’s blood. Blood collection can be done in any clinical analysis laboratory associated with GeneLab (see associated laboratories). You don’t need to fast, nor prepare for it. After collection, plasma is separated and DNA is isolated. This DNA is subject to a amplification technique for a region in the Y chromosome. The very high sensitivity of this technique enables the detection of small amounts of fetal DNA present in maternal blood. The test result is provided within 5 working days after maternal blood collection.

Note: this test only identifies presence or absence of the Y chromosome in maternal plasma. If a non-pregnant woman takes the test, it will indicate girl, because the woman only has two X chromosomes. You should always confirm your pregnancy, as well as the pregnancy duration at the time of conducting the fetal sex determination test.
