How accurate is MyHeritage DNA ethnicity?

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.
Which DNA test goes back the farthest?
The type of DNA testing that takes us back the farthest, according to most estimates, is mitochondrial DNA (mtDNA) testing. One reason that scientists can trace mtDNA back further than Y-DNA is mtDNA mutates more slowly than Y-DNA, and because we have copies of mtDNA in almost all of our cells.
Can a DNA test tell you your ethnicity?
The answer as to whether a DNA test can tell you your ethnic identity? Yes — and no. Direct-to-consumer ancestry companies offer just this kind of “admixture” test, and it is not uncommon for consumers to be told that they have a certain percentage of African, or Asian, or Native American DNA, for example.
