Is it worth it to get 23andMe?
In our opinion, it is the best overall genetic test for your average test taker. However, if you intend to do some hardcore ancestry research or if your primary goal is to find long-lost relatives, other tests, such as those from Ancestry DNA or Family Tree DNA, might be a better option for you.10 May 2019
How accurate is an ancestry DNA test?
Accuracy is very high when it comes to reading each of the hundreds of thousands of positions (or markers) in your DNA. With current technology, AncestryDNA has, on average, an accuracy rate of over 99 percent for each marker tested.
Can ancestry DNA matches be wrong?
Can DNA matches be wrong? Yes, it is possible for distant DNA matches to be false. It is most common to have false DNA matches that share a single segment that is smaller than 10 centimorgans (cMs) in length.
Is ancestry 100% accurate?
With current technology, AncestryDNA has, on average, an accuracy rate of over 99 percent for each marker tested.
How often is ancestry com wrong?

Why 23andMe is not accurate?
A major shortcoming of the genetic tests offered by the Google-backed company 23andMe is not necessarily their accuracy, but rather the limited information they use to evaluate a person’s lifetime risk of complex diseases, experts say.
Is 23andMe accurate for ancestry?
Because Ancestry Composition breaks your genome into thousands of segments, our models can give us a view into very small portions of your genome (what we may call “highly precise”). Our algorithms make ancestry estimates based on probabilities and they’re generally very accurate, but your results are not set in stone.
How reliable is 23andMe?
Each variant in our Genetic Health Risk and Carrier Status Reports demonstrated >99% accuracy, and each variant also showed >99% reproducibility when tested under different laboratory conditions.
