How to tell if an online DNA test is legitimate 

How to tell if an online DNA test is legitimate 

There are many varieties of DNA testing, some that are extensive scans of your DNA and some that provide focused or partial information. You can test for information about ethnicity, you can search for genetic relatives by matching their DNA, or you can search for information with medical significance. Some of the options you can only have through a medical provider, and others you can order for yourself directly over the Internet.

It’s hard to know who to trust, especially if you find them on the Internet and order the test for yourself. As a person who has taken many of these tests and a licensed and certified genetic counselor who works with people who test, I’ll explore the benefits and limitations of these testing options next.  

How do you check out an online DNA test for its reliability?

How do you know if a DNA company you found online is reputable? And whether its results are reliable? These are common questions. And they are difficult to answer.

If you're asking about tests that will give you ancestry or genealogy information, the International Society of Genetic Genealogy is a great place to turn. Their beginner's guide section has a list of articles to get you headed down the right track. I've also written about choosing between the options in this area of DTC testing before and linked to other articles with advice in this blog post.
