Due to New York State Department of Health regulations, we cannot offer any peace of mind paternity or relationship tests to New York residents. However, we can offer legal paternity and relationship tests in New York. Contact us or click here for more information.

Siblings DNA test

Order Now $299

If you need to know whether you and your sibling share both biological parents, just one of them or none of them, our siblings DNA test is your answer. A siblings test is done to determine the statistical likelihood that siblings share the same biological parent.

Aunt, Uncle DNA Test

Order Now $299

An avuncular test will establish whether an aunt and/or uncle is/are the biological relatives of their niece or nephew. The test is normally done when the only means of establishing paternity is by testing the alleged father’s relatives to see whether they are related to the child in question.

Grandparent DNA Test

Order Now $299

Grandparentage DNA testing shows whether a grandmother and grandfather are the biological relatives of their grandchild. This test is often done in the place of a paternity DNA test in cases where the biological father of a child is unavailable or deceased.

Are you sure about whether your twins are identical or fraternal? The only way of knowing is by doing a twin DNA test. A twin Zygosity DNA testing will determine if your twins are identical (monozygotic) or fraternal (dizygotic). The results of this test are 100% accurate.

Y Chromosome Test

Order Now $299

Y chromosome testing is used to determine if two males share the same paternal lineage. It can also be used in cases where male cousins want to see if their fathers were brothers or to check if they shared a common grandfather through the paternal line.

X Chromosome Test

Order Now $399

If you are females who need to know if you have the same father, our X chromosome test could provide you with the answers you need. Our X chromosome test uses a 10 genetic marker profile. A match between profiles means the individuals share the same father.

Mitochondrial DNA Test

Order Now $399

The mitochondrial DNA test is ideal in instances where individuals wish to prove a shared maternal lineage. The MtDNA test takes a segment of your MtDNA (mitochondrial DNA) and compares it with other tested individuals to determine whether there is a common maternal line.

Maternity DNA Test

Order Now $119

In much the same way as a paternity DNA test establishes the biological relationship between father and child, a maternity DNA test proves the biological relationship between mother and child providing you with 99.99% accurate results in just 3-5 working days.

Genetic Reconstruction Test

Order Now $433

Do you need to establish the paternity of a child but are unable to carry out a paternity test? In such cases, a genetic reconstruction test is a great way of establishing paternity without the need to directly include the father’s DNA sample.


 

FAQs

Why carry out a relationship test?

Generally, relationship DNA testing is a means of establishing paternity in cases where the father is not available and therefore, a straightforward paternity test is not an option. In such cases a grandparentage test or an avuncular DNA test can substitute a paternity DNA test. Siblings may also do a sibling DNA test, which will establish the extent of the sibling relationship: half siblings, full siblings or not siblings. The below are the relationship DNA tests we offer. This said, no relationship test will provide the same conclusive results that can be given in a home paternity test.

What will the results of a relationship test tell me?

This is not a clear-cut question with a single answer as different tests will give you different answers and not all tests are equally accurate. Some tests might just give you a probability of relationship and others might give you a definite yes you are related result. Again, for more information and details about any of our DNA tests, you can contact our team who will give you all the information you need.

How do I go about deciding on the type of test to carry out?

When you look through our range of relationship testing services, you will probably immediately know which one you require as soon as you skim the first sentence. However, we can give you 2 basic questions to help you decide on your test:

  1. What do you want to establish?
  2. Who is available for testing?

What you wish to establish refers to what you hope to find out with the DNA test result. Have a clear question in mind, for example “I want to know if this woman is my biological grandmother” or “I want to find out if my brother and I share the same father”. This will help decide if you need a siblings DNA test, avuncular test etc.

Who is available for testing is crucial and an often overlooked factor when deciding on a relationship test. You may want to know whether you and your brother share the same father but is your brother willing to submit his sample? homeDNAdirect suggests you contact our customer support team to help you decide on the best relationship test.
