While every pregnant woman has her own DNA in her bloodstream, a pregnant woman’s bloodstream also contains DNA from her unborn child. We look for male chromosomes in a small sample of mum’s blood. If male chromosomes are found, that means baby is a boy. If none are found, baby is a girl. The test is 99.9% accurate at 6 weeks into pregnancy.
At the Labs, a test process called non-invasive prenatal testing (NIPT) is used to analyse cell-free fetal DNA. Starting with a small sample of blood from mum, plasma is separated from whole blood by centrifuge, and extracted cell-free fetal DNA (cffDNA) is analysed for Y chromosomes, which are found only in males. The test is sensitive enough to find even a single Y chromosome, giving you confidence in your results.
Results come in the from of an email or a face to face appointment, you can come back to clinic with your nearest and dearest to find out or get a special email. If finding out via email you can have this email sent to someone else if you would like to find out the gender at a reveal etc.
100% its is a simple blood test and apart from the slight discomfort from this there is nothing that makes this process unsafe whatsoever.
No blood thinners or other drugs are known to impact the gender results.
The test looks for male DNA in the fetal DNA found in mum's blood sample. In the case of identical twins, if male DNA is found, then both babies are boys. If no male DNA is found, then both babies are girls. For fraternal twins, finding male DNA means at least one baby is a boy, but cannot distinguish if the second is a boy or girl and you will need to rely on scan sexing from 16 weeks gestation.
