Consequently, are ancestry DNA tests ever wrong?
One recent analysis found 40 percent of variants associated with specific diseases from “direct to consumer” (DTC) genetic tests were shown to be false positives when the raw data was reanalyzed. Assuming the tests are done accurately, some discrepancies can still arise from differences in the companies' DNA databases.
Furthermore, are ancestry DNA tests reliable? Reading your DNA is a first step in generating your AncestryDNA results. 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.
