Are there different types of DNA tests?

When you think of DNA tests, the first thing that comes to your mind might be paternity tests – perhaps alongside a tearing of an envelope and the declaration that someone is or is not the father. But there are plenty more uses for DNA tests – some that don’t have anything to do with paternity at all! For example…

  • Ancestry tests: You probably already know all about these, due to the popularity of companies like “23AndMe” and “Ancestry.” DNA tests can be used to tell you all sorts of things about your bloodline, like where your ancestors were from and your genetic makeup! 
  • Paternity: A simple test used to determine if the participant is or is not the father of a specific child.
  • Grandparentage: Just like paternity tests, grandparentage tests are a simple cheek swab, but unlike a paternity test the analysis is more complicated – instead of a clear-cut yes or no, it yields a probability scale.
  • Avuncular: Avuncular DNA tests are similar to grandparentage tests, but with an aunt or uncle instead of a grandparent. It’s used most commonly in a situation where a presumed father is not available, but a sibling is. 
  • Siblingship: Similar to avuncular and grandparentage, a siblingship test can establish or rule out a sibling relationship between two people.
  • Unknown substances (razor, toothbrush, fingernails, etc.): All of the above tests are most commonly done with a cheek swab, but other sources of DNA can also be used (particularly for paternity tests, as though are the most simple and conclusive). A toothbrush can even be used as long as the person has been using it for at least 60-90 days! Of course, consent is required.

As you can see, there are many different kinds of DNA tests, and they can be invaluable for a multitude of reasons. What sort of things are DNA tests useful for?

  • Adding or removing a father’s name from a birth certificate: If a paternity test uncovers that someone either is or is not the father of the child, his name can be either added to or removed from the child’s birth certificate
  • Child support claims: If it can be proven that a man is or is not the father of a child, he either will or will not have to pay child support if he does not have full custody of the child
  • Child custody hearings: In the event of any custody disputes, DNA knowledge like paternity may be essential to a good result.
  • Estate matters (inheritance rights): In order to receive an inheritance, or to contest inheritance claims, a DNA test may be performed.
  • Infidelity cases in divorce proceedings: If there is proof that a partner was infidelious during a marriage through a DNA test, that will affect divorce proceedings
  • Life insurance claims: To receive life insurance payouts, you may have to prove you are related to th: For example, if your children’s father’s name is not on their e deceased party. 
  • Individuals seeking social security, health, or military benefits: you may have to perform a paternity test to confirm he is their parent in order to receive benefits.
  • Immigration: To prove that you are closely related to a citizen of the country you wish to immigrate to.
