X–SV Female Lineage DNA Testing
Peace of Mind Female Lineage DNA Test kit just £29*
Legal DNA Test kit just £29*
The GTL X-SV Female Lineage DNA Test determines whether or not two or more applicants are related by their maternal lineage, or if male and/or female children share the same biological mother. The Mitochondrial DNA sequence variation has a comparatively infrequent mutation rate and therefore remains the same through many generations when it is passed on from mothers to their children. NOTE: males do not pass on to their children the Mitochondrial DNA sequence variation they inherited from their mother.
This DNA test focuses on Mitochondrial DNA and produces a unique X-SV DNA profile for each tested applicant. It is very important to note that this DNA test will not distinguish between females of the same maternal lineage or applicants with the same mother.
For example: a female “A” and her alleged half brother “B” know they have different fathers but would like to find out if they have the same biological maternal grandmother. If the X-SV DNA profiles produced by the X-SV female lineage DNA test are the same then it is practically proven that they share the same maternal lineage. If the X-SV DNA profiles do not match then they do not share the same biological maternal grandmother and they do not share the same maternal lineage.
The chart above and to the right illustrates other circumstances in which a X-SV female lineage DNA test can be used.
If you have any questions regarding the additional costs of testing more than two applicants please email us or call one of our Customer Service Advisors on 0333 300 3130.
IMPORTANT NOTE: This DNA test can only be used to determine female lineage. Other DNA tests may be more suitable for your circumstances. Please email us or call one of our Customer Service Advisors on 0333 300 3130 for more information.

Rush Analysis of DNA
If yours is a more urgent case and you require a faster turnaround time, we provide a Rush Processing service at additional cost, please see below for full details. Please note that the X-SV female lineage test takes 10 working days to complete and rush processing times are therefore calculated differently.

Should you find you are unable to provide a mouth swab sample, or do not wish to concern or upset your child by collecting a DNA sample in this way, we are able to extract DNA from a variety of other sources at additional cost. These alternate sources include hair, nail clippings, chewing gum, cigarette butts and clothing. Please click here for full details of other DNA sources we can work with, prices and success rates.
