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 the womb.

This type of test uses a blood sample from the mother (from 6 weeks into pregnancy), which can be used to 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 indicates that the 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 look for the presence or absence of a Y chromosome within the mother’s blood.

If a Y chromosome is detected, the baby is a boy. If no Y chromosome is detected, the baby is a girl.

AlphaBiolabs’ baby gender testing is over 99.6% accurate and uses a multi-copy Y target that analyses multiple loci on the Y chromosome for greater accuracy, making it incredibly sensitive.

How accurate is a blood test for gender?

Baby gender testing using a blood sample from the mother is the most accurate way to determine a baby’s sex before the baby is born.

This advanced scientific method can determine whether your baby is a boy or a girl from as early as 6 weeks into pregnancy with over 99.6% accuracy.

For the highest chance of a conclusive result, the mother must be at least 6 weeks pregnant when providing a blood sample for testing. This is to ensure that any Y chromosome present is at a detectable level.

AlphaBiolabs’ baby gender testing uses a multi-copy Y target that analyses multiple loci on the Y chromosome for greater accuracy, making it incredibly sensitive.

While other laboratories may offer finger prick blood testing for baby gender, this is not something we offer at AlphaBiolabs, as it is much more difficult to prevent male DNA contamination when collecting a blood sample from fingertips.

Contamination with male DNA can affect the results of a baby gender test, leading to a false result.

In addition to being easy-to-use, convenient, and pain-free, a major benefit of our TinyTAP device (which is used to self-collect a small sample of blood from the upper arm) is that it greatly reduces the likelihood of male DNA contamination, resulting in a much more accurate and trustworthy test result.
