Exploring Different Types of Paternity Tests: A Guide

Published on 14 Mar

Paternity testing can be helpful in numerous situations, from establishing legal rights to uncovering family history. If you’re considering a paternity test, you have to know the different types available and how they can benefit you. At thatDNAcompany®, we’re dedicated to reliable and affordable DNA testing. 

As a leading UK paternity test provider, we offer a range of tests and other relationship analyses. We’ll explain our distinct types of paternity tests, outlining their uses and helping you decide which option suits you best.

What is a Paternity Test?

A paternity test determines whether a man is the biological father of a child. It works because every person inherits half their DNA from their mother and half from their father. During the test, experts compare specific DNA markers of the child and the alleged father. A substantial match indicates a biological relationship with extremely high probability.

Benefits of Paternity Testing

Paternity tests have many benefits. Here’s a closer look at a few key benefits.

A paternity test can legally establish a father’s responsibility to provide financial support for his child, ensuring the child’s well-being. Test results can help determine custody arrangements or solidify a father’s right to visitation with his child, fostering a strong parent-child bond.

Moreover, a paternity test clarifies inheritance rights. If a father passes away, his biological children can rightfully receive any inheritance they may be entitled to.

Paternity tests are necessary in many immigration applications. They provide irrefutable evidence of biological relationships, helping families reunite or secure citizenship.

Knowing your child’s complete family medical history, including the paternal side, is invaluable. It can help identify potential health risks the child may have inherited, allowing for early detection and proactive management of medical conditions.

Types of Paternity Tests at thatDNAcompany®

Father and Child Only Paternity Test

This is the standard paternity test used to determine the biological relationship between a single child and one alleged father. Ideal for personal knowledge, commonly known as a peace of mind test. The father and child-only paternity test is the simplest option for establishing paternity.

Two Children and One Father Paternity Test

This testing option is used when there is a need to confirm paternity between two children and the same alleged father. Full siblings commonly undergo testing together to clarify family history. The two children and one father paternity test is also useful in answering questions about paternity for two children within the same family.

Three Children and One Father Paternity Test

Similar to the previous test, this option includes an additional child. It’s often used for personal confirmation of paternity within larger families (three full siblings). In complex situations, you can also use the three children and one father paternity test to expand previous testing results to include a third child.

One Child and Two Father Paternity Test

This test specialises in situations where there is uncertainty about the biological father of a single child, with two potential candidates. The one-child and two-father paternity test gives clarity in cases of contested paternity to establish which of the two possible father’s is the true biological father.

If you require any of these Paternity Test’s for a legal purpose, such as Immigration or Birth Certificate changes, please get in touch with us before ordering as we will need to arrange a legally admissible DNA test through our sister service, dadcheck®.
