With so many DNA genealogy tests on the market, how can you know which one is best for your family tree research? Top 10 DNA Tests present their guide to choosing the best DNA test for your needs.

Top 10 DNA Test's decision making tool defines all DNA test categories and suggests what questions to ask before parting with any money. 

A look at the different DNA tests

DNA tests are many, but they can be broadly sorted into three categories:

  • Relationship tests – These tests are used to establish potential genetic connections between two or more people. This is a basic paternity/maternity test, but this group contains much more than that, including relations such as uncle/aunt, twin, grandparents, siblings, family reconstruction, male/female lineage, etc.
  • Ancestry tests – They provide a (pre)historic picture of your genetic ancestry, allowing you to see regions around the world with the highest concentration of your DNA throughout history, look at genetic and ethnic maps, determine percentages of residue Neanderthal DNA in your genome, as well as identifying unknown relatives and connect with them if you wish.
  • Genomic tests – According to the NHGRI (National Human Genome Research Institute), these tests are used to determine potential “risk-carriers” within your genome; genes able to cause genetic disorders. Having the information in advance helps people choose treatments and assess their effectivity over time. Many chronic diseases have a genetic component, so uncovering your family history can be important in this respect.

How to choose a DNA genealogy test provider

Here is Top 10 DNA Test's advice on choosing the best DNA testing company for your needs:

  • DNA database – Every company has its internal database comprised of its customers. The larger the database, the more potential DNA matches. This is the most important factor for ancestry and health DNA tests.
  • Legal test option – This applies to relationship tests - can the company provide a court-viable document? At-home tests are never admissible in courts or other state-sanctioned bodies, since the chain of custody cannot be established beyond doubt
  • Scientific credentials – Is the company renowned in the world of genetic genealogy? Does it employ famous experts? Does it have internationally acclaimed certificates or backing?
  • Test quality – Find out how many genetic markers are being checked, What technologies are they using and the turnaround time. What different features does their membership offer? What are the accuracy percentages/error margins?
  • Service quality – Questions to ask include - will they keep your information safe? Is their customer support good? Do they update your test results automatically? Do they offer consultations and results reviews? How many times do they perform each test to minimize potential errors? How long do they store your sample? Is your raw data available to you?
