DNA Relationship Testing

easyDNA UK offers DNA Relationship Testing priced from only £269. This type of DNA testing can be used to establish if two or more people are biologically related. These tests are particularly useful in situations where the alleged parents are unavailable for testing. For example, a DNA Siblings Test can be performed to establish if a biological relationship exists between potential siblings in cases when the alleged father is not available for testing.

Relationship testing is slightly more complex than standard paternity testing and can be used to determine various types of relationships in different situations. Depending on the people available for the DNA test, there are several different methodologies that can be used according to the alleged relationships.

easyDNA offers the following types of Relationship Tests:

• DNA Siblings Testing
• Grandparentage DNA Testing
• Aunt-Uncle DNA Testing (Avuncular Test)
• Twins DNA Testing
    

Siblings DNA Testing                                      Order Here

Siblings DNA testing is ideal in situations where two alleged siblings want to confirm their biological relationship and verify if they are full or half siblings or possibly not related at all. The siblings DNA test can be conducted with or without the parent’s sample.

easyDNA can confirm if two people are related by sharing one or both parents, meaning that they are either full or half siblings. In the case of half sibling testing, the sample of the known parent (normally the Mother) is recommended to strengthen the results of the test if available.

• In cases where the siblings are males, and want to establish if they share the same father, we recommend using a Y-Chromosome Test which is able to determine male lineage. Visit our Y-Chromosome Testing page for more information on this test.
   
• In cases where the siblings are females, and have different mothers, an X-Chromosome Test can be used to determine if they have the same father. Visit our X-Chromosome Testing page for more information on this type of test.
   
• If siblings are either sex and wish to confirm maternal lineage, then an mtDNA test can be used. Visit our mtDNA Testing page for further information on this test.

Siblingship testing is priced from £269. Results are available in 5-7 working days from the receipt of samples at the laboratory. A DNA testing kit will be sent to you immediately once we confirm your order.
