AlphaBiolabs launches its market-leading DNA test

All relationship DNA tests work in the same way – by analysing the DNA samples of individuals and comparing them to identify matching DNA at a number of markers (loci).

Every person inherits half of their genetic material from each of their parents, meaning that individuals who are biologically related are likely to share more DNA markers than individuals who are unrelated.

Paternity testing

When we talk about DNA relationship testing, we usually think about paternity testing, as this is one of the most common DNA relationship tests. It is frequently used to determine a child’s biological father in child maintenance or custody disputes, but is also used for inheritance or immigration cases.

The test produces 100% accurate results and is completely non-invasive, as cheek cell DNA is simply and painlessly collected from each sample donor using buccal (cheek) swabs. The samples are then analysed and compared in the laboratory to determine the likelihood of the individuals being related.

For paternity testing cases, we always test 25 DNA markers as standard, as this gives a 99.9% chance of obtaining a conclusive result.  The AlphaBiolabs standard paternity test is already industry-leading, as it analyses 25 DNA markers, whereas the industry norm typically only analyses 16-21 markers.

Our 25-marker test is therefore almost always sufficient to obtain a conclusive result.

However, what makes AlphaBiolabs unique is that we can now analyse up to 45 DNA markers. This allows more genetic material to be analysed, which strengthens the result and provides additional reassurance.

Our 45-marker test is the most powerful DNA test available and increases the chance of obtaining a conclusive result to over 99.99%.

It is also particularly useful for paternity DNA tests:

• Where a close male relative may be the biological father of the child
• In cases that do not include the mother’s sample
• Simply where additional reassurance of a result is preferred

Complex relationship testing

Complex relationship tests include siblings, grandparents, aunts, uncles, and cousins. These tests are especially useful where an alleged father is unavailable or unwilling to participate in paternity testing, or where the alleged father has passed away.

Our advanced and industry-leading 45-marker test is particularly suitable for complex relationship testing, where the chance of obtaining a conclusive result will always be lower than the more straightforward paternity or maternity tests, as the DNA hasn’t been directly inherited.

The enhanced 45-marker test will increase the chance of obtaining a conclusive result.

There are several options for complex relationship tests to suit a range of needs, including:

Grandparent testing – enables us to verify a relationship between a grandparent and a grandchild. Every person inherits half of their DNA from each of their parents, meaning that a grandchild will also share DNA markers with their grandparents. The advanced 45-marker test is recommended for this test type, as it will significantly increase the chance of obtaining a conclusive result.

Sibling testing – allows us to establish whether two or more siblings have the same father or mother (or both). Full siblings usually have more DNA in common than half siblings, while half siblings normally share more DNA than unrelated persons. The advanced 45-marker test is recommended for this test type, as it will significantly increase the chance of obtaining a conclusive result.

Aunt/uncle (avuncular) testing – a useful test when the alleged parent of the child is unable to provide a sample. However, the sample donor must be a full biological sibling of the alleged mother or father, as this helps increase the likelihood of a conclusive result. Again, the advanced 45-marker test is recommended for this test type, as it will significantly increase the chance of obtaining a conclusive result.

Cousin testing – at AlphaBiolabs, we also now offer cousin testing, which tests for 45 markers as standard. Parents and siblings, if available, should also be included as sample donors to further increase the chance of achieving a conclusive result.
