There are three primary forms of commercial DNA tests: paternity tests, ancestry DNA tests and animal tests. All three follow similar analytical procedures but have very different purposes. If you’re looking to test your DNA, you obviously know your reason for doing so, which means it’s just a matter of finding which kit best suits your purpose. For this buying guide we chose to focus exclusively on human DNA testing products, some of which specialize in paternity and others in ancestral DNA.

A DNA test is an analysis of DNA strands to identify matching markers among ancestral strands and will give you an idea of where you come from. Certified laboratory technicians analyze your DNA sample and identify certain markers within your DNA strands. The technicians use these markers to compare your DNA to other strands and identify whether or not you’re related to another person or ethnic group. To learn more about DNA testing read our articles here. Here are some recommendations which take into account the different reasons people will be seeking DNA analysis:

Best Ancestral DNA Test

An ancestry DNA test gives you insight into your bloodline, ethnicity, family tree and ethnic group origins. is the best ancestral DNA testing for genealogy. implements the latest technology to create unique algorithms for genetic testing. The company has access to one of the most extensive worldwide genealogical databases. The results for this test take significantly longer than the average paternity test, six to eight weeks, but that is because paternity test labs are managing much less information than Ancestry’s DNA test labs. In contrast, when looking at your ethnicity this lab compares your DNA with thousands of samples.

Ancestry essentially provides a social network for family history. You can access a growing list of DNA member matches and find relatives you didn’t know existed by finding common matches in your family history.

We chose only to focus upon services that provide human DNA tests. Most of these are collected through buccal (cheek) swabs, which is the quickest and easiest form of DNA collection. People who are testing DNA are often doing so for personal or legal reasons and discretion is an important consideration. You can usually collect the samples yourself from the privacy of your own home and maintain privacy throughout the process. Taking into account the various types of DNA testing, here are some things to consider:

Ancestry DNA tests are typically slower to process than paternity tests. Part of this is due to the time sensitivity of paternity tests, and part of this is due to the size of the database an ancestry test is using. When you’re looking into your ethnicity, the lab specialists are comparing your DNA with thousands of other samples to identify your deep-seeded roots. In paternity tests, they’re only looking at a couple of samples.

Paternity tests are stressful enough, and they’re often tied up in legal disputes. Because of this, time is usually of the essence. You can typically get your results in a week or less, but some companies offer expedited options. Before buying, look at how quickly you can expect to get your results.

Legal and Forensic Testing
Legal considerations are more relevant to paternity tests, because such tests can be used in court proceedings. In order for a test to be admissible in court, certain procedures must be followed. Some companies accommodate for this, while others explicitly state that their tests cannot be submitted.

A few DNA testing labs offer forensic testing. Forensic tests are slightly more expensive and more complicated than other DNA tests, but samples can be gathered from a variety of sources. Dried blood stains, underwear stains, saliva stains can all be tested, but the results can’t be guaranteed. To increase accuracy, two test samples can be tested and compared to determine if they are from the same person. Usually, each test sample will have to be paid for separately, however.

There are many standards and levels of accreditation for genetic testing labs. Genetic testing is an intensive and complex process, so it’s important that your lab is up to date, safe and secure. It's a good sign when a company has accreditation from organizations like the National Institutes of Standards and Technology (NIST), the College of American Pathologists (CAP) and Clinical Laboratory Improvement Amendments (CLIA).

DNA Tests for Pets
Though we focused exclusively on human DNA testing for our buying guide, there are a number of services that perform DNA testing for pets. Regarding testing for dogs, which is one of the most commonly tested animals, the same test is used for mixed and designer breeds or purebreds. If you know the ancestry of your pet, it is easier to customize a wellness plan for your pet’s needs. As with human testing, you can also test for inherited diseases and identify genes that cause allergic reactions to different types of medication.

Technology has made DNA collection and submission quick and easy, which is good news for anyone needing a paternity test or simply wanting to delve into ancestry research on the most personal level. The same technology has led to more competitors in the genetic testing space, which means more options but also more variations in the quality of testing. If you are looking for a paternity test, you will seek results from a very different DNA test lab than if your interest is genealogy DNA testing, but either way you will want to make an informed decision about which company best fits your needs.
