What is a blood test for gender?

A blood test for gender – also called a baby gender test or prenatal gender test – is a type of DNA test used to verify the gender of an unborn baby while they are still in utero (in the womb).

This type of test uses a blood sample from the mother (from 8 weeks into pregnancy) to identify foetal DNA and determine whether any Y-chromosomal DNA is present.

If a Y chromosome is present, this indicates that the baby is a boy. If there is no Y chromosome present, this means that baby is a girl.

How does a baby gender test work?

Every human being has a pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes.

For a baby gender test, the mother’s blood sample is analysed by expert geneticists, who use Next Generation Sequencing to determine if foetal DNA with a Y chromosome is present in the mother’s blood stream.

If a Y chromosome is detected, this indicates that the baby is a boy. If no Y chromosome is detected, this means that the baby is a girl.

How accurate is a blood test for gender?

A blood test is the most accurate way of determining a baby’s gender before he or she is born.

Although ultrasound scans are commonly used to determine the gender of an unborn baby between weeks 19 and 20 of pregnancy, these scans are not always correct.

This is because if the ultrasound technician cannot get a clear view of the baby’s genitals, it may not be possible to confirm whether the baby is a boy or a girl.

The results of an AlphaBiolabs Baby Gender Test are 100% accurate and reliable based on the samples we receive at our laboratory.

We use state-of-the-art processes to identify foetal DNA within the mother’s blood sample and determine whether any Y-chromosomal DNA is present. If a Y chromosome is present, this is indicative of a male child. If a Y chromosome is not present, this is indicative of a female child.

For the highest chance of a conclusive result, the mother must be at least 8 weeks’ pregnant when providing a blood sample for testing.

This is to ensure there is enough foetal DNA in the mother’s bloodstream for the Y chromosome (if present) to be at a detectable level.

What samples are required for a blood test for gender?

An AlphaBiolabs Baby Gender Test requires a blood sample to be collected from the mother by an AlphaBiolabs clinician or another medical professional (e.g. nurse or phlebotomist).

You can choose your preferred method of sample collection from the options below, when placing your order:

• Organise your own sample collection by a trained medical professional (e.g. at your doctor’s surgery)
• Arrange an appointment to have your sample collected at one of our nationwide walk-in centres (additional charges apply)
• Arrange an appointment for a professional AlphaBiolabs sample collector to visit you at an address of your choice (additional charges apply)

It is very important that the mother is at least 8 weeks pregnant when providing a blood sample for testing, for the highest chance of a conclusive result.
