Many of the best at-home DNA kits are on sale right now to celebrate National DNA Day - here's a quick break down of each one

The 23andMe kit is one of the most in-depth at-home DNA tests you can take. Not only will it break down your ancestry, but it will also discover your genetic health risks for diseases like Parkinson's or Alzheimer's, carrier traits for diseases like Cystic Fibrosis and Sickle Cell, report on your wellness with details like sleep patterns and lactose intolerance, and other genetic traits. If you're only interested in learning your ancestry you can buy the genetics kit for $69 — a $30 savings.

The National Geographic Geno 2.0 Next Generation provides a breakdown of your regional ancestry by percentage, going back as 500,000 years. Once your DNA sample is submitted and processed, you can access the data via the Geno 2.0 smartphone app, where an easy-to-understand video walks you through your ancestry. You'll learn about which historical relatives you could be related to.

MyHeritage DNA is one of the easiest DNA tests to complete. Unlike other tests that require several vials of saliva, this test can be completed in two minutes with a simple cheek swab. With a huge database of DNA Matches, the test pulls data from 42 regions. Once your results are in, you'll learn about your ancestry and potential family members you've never met.

Family Tree DNA offers an in-depth genetic analysis of your genetic makeup by regions as well as your lineage over time. It is also is one of the best tests for finding and connecting with distant relatives. The Family Matching System pairs other users with similar genetic make-up, so if you're looking for a long lost sibling, there's a decent chance you'll find them here.

Vitagene is another great test for learning about your ancestry as well as your health. The easy two-minute saliva test is processed in 4-6 weeks (which is a lot quicker than most other tests), and you'll get a full breakdown on your ethnic mix and global ancestry. The health insight comes as a diet plan, fitness plan, and a personalized vitamin plan tailored to your DNA. You can save 20% on all other Vitagene kits here.

Living DNA is a three-in-one kit that breaks down your ancestry by revealing which countries or regions of the world you're from, your maternal family line, and your paternal family line (if you're a male). While just about every other kit on the market provides some sort of data on your ancestry, Living DNA will allow you to specifically trace your mother and father's roots over the course of many generations.
