Relationship DNA Tests

There are many different types of DNA tests available to you, depending on your needs. Sometimes people want to test their twins to see if they’re identical or fraternal, for example. Or you may want to get a test done to determine whether someone is a biological grandchild. We can take care of any of your needs when it comes to relationship DNA tests, so contact us for help. Below are several types of relationship tests that we can arrange:

Avuncular Testing

If you need to find out if someone is a biological aunt or uncle to a child, this is the test we can perform. The fees range from $420 for non-legal tests to $500 for legal testing.

Grandparent-age

In these cases, we recommend that both grandparents, if possible, take the DNA test to determine if a child is biologically related to them. Call for the prices for grandparent-age tests (depending on the number of people tested and whether they are legally binding for court)

Sibling Testing

If you need to find out if someone is a biological aunt or uncle to a child, this is the test we can perform. The fees range from $420 for non-legal tests to $500 for legal testing.

Twin Zygosity Testing

Sometimes, it can be determined during delivery whether twins are identical or fraternal. Still, this is not a definitive ruling; only a DNA test will reveal the proof. The fees range from $400 to $475.

Y-Chromosome DNA Testing

This chromosome is found only in males and passes down from father to son. All men or boys in the same family, including cousins and uncles, share the same

Y-chromosome. These can be beneficial in determining the parentage of a child.

Mitochondrial DNA Testing

This type of DNA is passed down the maternal line from mother to both daughter and son, but the son doesn’t pass it down afterward.

The DNA Testing Process

Undergoing a DNA test is much simpler than many people would imagine. It just involves a quick swab of the cheek to get the DNA, which is then sent to our lab for processing.
