A maternity DNA test is done under any of the following circumstances:

An immigration test: immigration authorities may request a DNA test as proof of maternity. This will prove the biological relationship between mother and child.  If you need this specific maternal test, please read our section on immigration testing.

Cases of adoption: adopted children might want to test the person they suspect might be their birth mother to know if she really is their biological mother.

We offer our DNA maternity test starting from £99. This includes testing one mother and one child. Results will be emailed to you in just 3-5 days. For more information about homeDNAdirect, return to our DNA testing home page.

How are samples collected?

Our maternity test is done using sterile mouth swabs which we send you in our easy to use, at-home DNA testing kit. Kits contain enough mouth swabs for up to 3 individuals and each individual will have 4 swabs. Rubbing the swabs inside the mouth of the mother and child will result in check cells adhering to the swab. These cheek cells are what we require for laboratory analysis. At the laboratory, the DNA is extracted from the cell and specific regions of the DNA are amplified by a process known as PCR (polymerase chain reaction).

Maternity testing results

Maternity test results will show what is referred to as a probability of maternity and the test is based on the analysis of a total of 21 genetic markers. For a conclusive result which confirms the tested mother is the biological mother, all 21 genetic loci will need to match on the DNA profile of the child and mother. If the tested female is the biological mother of the child, the result will show a 99.99% probability of maternity. If genetic markers do not match, the mother will be excluded as the biological mother and the results will show a probability of maternity of 0%.
