As you are probably aware from TV and the media, DNA tests can serve many purposes.

For example, DNA tests can be used to discover your ancestry, identify lost relatives, verify paternity & sibling relationships and identify people who have died.

One of the newest and fast-growing uses of DNA analysis is in researching your family history, a field of study known as genetic geneaology.

According to the website MyFamilyDNATest.com, Ancestry DNA testing is the use of personal autosomal DNA analysis to accomplish one of three things:

  1. identify new/missing relatives
  2. Build a family tree
  3. Understand your long-term ethnic family history.

When looking for the best ancestry DNA test, however, there are many factors to be aware of.

Here are the top 4 things you should consider when purchasing an ancestry dna test.

The “Big Three” Ancestry DNA Test Providers

According to authority sites ISOGG.org and MyFamilyDNATest.com, the top 3 providers of DNA tests for ancestry research are AncestryDNA.com, FamilyTreeDNA.com and 23AndMe.com.

Together, the three leaders hold more than half of all DNA ancestry records online.

Each provider offers something a little different. Selecting the right one for your needs boils down to 4 factors:

It’s important to do your research to find out exactly how accurate each vendor’s tests really are.

One of the ways to do this is to observe their method of collecting the DNA samples. In general, mouth swabs and blood tests are considered more reliable than hair and other sampling methods.

In order to have the best Ancestry DNA test, the collection process also needs to be handled by professionals who know what they are doing. If you try and collect the sample yourself (for example, using a home test kit), it can be easily contaminated and cause faulty results. The test kit needs to be well designed and instructions crystal-clear.

  1. Affordability

This particular factor isn’t as important as some of the others, but it can definitely play a part for those who are looking to pay for a personalized ancestry DNA test.

Being able to trace your family history and find missing links in your family tree can be a very enlightening and positive experience.

However, if it’s going to cost more than a couple of hundred dollars, you’re probably not going to do it. Luckily, all three leading providers offer an affordable and accurate service for $99.

  1. Accreditation

Accreditation is definitely crucial when dealing with DNA testing. This helps to prove to other businesses, as well as consumers, that the methods for collection and testing are the best that they can be. It also helps to prove the quality of their results. Services that have accreditation can be more expensive, but the benefits of the accreditation definitely outweigh this negative aspect.

  1. Reliability

The reliability of the testing provider is also important when dealing with both DNA tests and can also be a key factor in finding out accurate genealogy.
