It is now possible to establish the gender of an unborn baby just 8 weeks into a pregnancy. A simple blood sample is all that is needed. The non-invasive DNA test is quick, accurate and risk-free.

AlphaBiolabs’ baby gender testing costs just £199 with results in 7 working days. We also offer an express service where results can be returned in just 4 working days (for an additional £60).

The test kit can be ordered direct from our website and mailed to an address of your choice. Full instructions on how to collect your blood sample are included. You can choose from three options for sample collection:

  • Have your blood sample taken at one of our nationwide Walk in Centres;
  • Have one of our sample collectors visit a place that is convenient to you; or
  • Organise your own blood sample collection from a trained medical professional.

The test works by analysing the foetal DNA detected within the mother’s blood sample. It is important that the mother is at least 8 weeks’ pregnant to ensure that any foetal DNA present is at a detectable level. If the blood sample has insufficient DNA then another blood sample will need to be collected a minimum of 2 weeks after the original one. Our pregnancy calculator can help a mother work out how many weeks pregnant she is.

The advantage of this baby gender test is that it can be performed at a much earlier stage than waiting for the mid-pregnancy ultrasound scan (from around 16 weeks) to determine whether the baby will be a boy or girl. In addition, statistics show that ultrasounds can be wrong up to 10% of the time.

How does baby gender testing work?

If foetal DNA can be found within the mother’s bloodstream, a technique known as Next Generation Sequencing is used to look for any Y-chromosomal DNA. Because the Y chromosome is specific to males, any presence in the foetal DNA is indicative of a baby boy. If foetal DNA is detected without a Y chromosome it would suggest a female child.

This baby gender test can even be performed in twin pregnancies to tell whether at least one of the babies is male, or if all the babies are female.
