Gender Reveal Test – From 6 Weeks Pregnant

1. If both babies are female, no male DNA will be found, and we can assume that both babies are girls.

2. If male DNA is found in mum’s blood then either one twin is a boy, or both are. It will NOT be able to tell the difference between a girl and boy, and two boys.

The presence of the Y-chromosome in the mothers blood can be detected at extremely low levels but no molecular test will ever be 100% accurate. There are a few rare circumstances where the test will not work. They include: placental mosaicism, a sex chromosome abnormality, a bone marrow or organ transplant by a male donor, or testing too early in pregnancy. It is essential we know the date of when mum’s last menstrual period started. To make sure there is enough foetal DNA in the sample the test should ideally only be ordered when mum is at least 6 weeks pregnant.

Please note, it is a fact that mum’s weight can affect how much foetal DNA is in her blood. Mum’s over 85kg should only do the test after 10 weeks pregnant, as there is a slightly higher chance that there will not be enough male DNA in her blood to be detected between 6 – 10 weeks.

Not at all. It is completely safe for both. The test only requires a single blood tube from the mum’s arm, no different to going for a routine first or second trimester blood test.

If we are unable to draw a blood sample, we will offer a complimentary redraw to try again. If we are unable after the 2nd time, we will refund the blood test price minus our £50 admin and appointment fee.
