Who needs to be tested?
Two or more females who want to determine whether they are related through their maternal lineage or two siblings who want to determine whether they share the same biological mother can take this test. Females have a unique Mitochondrial DNA sequence variation which is passed down from generation to generation without changing. Males who inherit this DNA sequence from their mothers will not pass it onto their children.
The DNA Female Lineage test focuses on this Mitochondrial DNA sequence and creates an X-SV profile for each sampler. The test will then identify if there are similarities or matches in the two profiles. If the profiles match, it is proven with 100% accuracy that there is a maternal relationship between the two females. If the profiles do not match, there is no maternal lineage.
How do I take the test?
The DNA test is easy to use and will involve a mouth swab being taken from each subject being tested. You will receive two cotton swabs per person in separate envelopes. One swab is used to take a saliva cell sample from the inside left cheek, and the other swab is used to take a saliva cell sample from the inside right cheek. You should ensure that the cotton swab is completely dry before you place it in the envelope, and that you have clearly labelled each subjectís envelopes for processing. Itís important that you do not consume any coffee, alcohol or tobacco-related products at least four hours before the test. Detailed instructions for how to take each test will be included in your test kit.
What female lineage tests are available?
There are two types of X-SV female lineage tests available from TestDiagnostics Ė a peace of mind female lineage DNA test or a court approved female lineage DNA test. A peace of mind X-SV female lineage test can be used for personal reasons only and does not need to be overseen by a third party or medical professional. However, it is important to note that this type of test cannot be used for legal or immigration purposes.
A court approved DNA test can be used for all legal purposes, and requires that a neutral third party or medical professional perform or witness the swab collection. The test subjects submitting their DNA samples must also provide the third party with recent passport photos as well as positive photographic identification such as a passport and utility bill. Please note that this medical professional must be organised by the test subjects themselves and may charge an additional fee which is not included in the TestDiagnostics fees.
