Dog DNA test accuracy depends on the laboratory method, the reference comparison approach, the sample quality, and the kind of result being discussed. uDNA uses this page to explain accuracy without oversimplifying it.
A breed estimate and a disease marker screen are not measured in exactly the same way.
Clean collection and correct labeling help the process work well.
A perfectly run test still cannot answer the wrong question.
uDNA uses articles like this to slow the decision down in a useful way. The more clearly you understand the question you are trying to answer, the easier it becomes to choose the right product page and avoid ordering a vaguely related test.
That is especially important when the difference between a focused screen, a broader panel, and a record-oriented service can change what the report actually means.
