23andMe is an excellent DNA ancestry test because of its highly specific results and vast geographic reach – it serves more than 1,000 geographic regions worldwide. The service tests autosomal, mitochondrial and Y-DNA to give you a complete picture of your genes. Four testers took 23andMe DNA kits during testing. We received our results 32 days later, and testers were highly satisfied with the overall experience, from ease of sample collection to the thoroughness of the results. Recently, the company updated its database and increased the number of geographic regions from around 170 to more than 1,000. The updated ancestry reports are also more detailed, especially for non-European regions. 23andMe’s ancestry tests give you information split into several different reports spanning your ancestry composition, maternal and paternal haplogroups, neanderthal ancestry and DNA family. Testers particularly liked the timeline feature, which estimates when your most recent ancestor lived in each of your matched regions. While 23andMe does offer DNA relative matching and some tools to compare your genes to your DNA relatives, it doesn’t have robust genealogy tools, as its focus rests more in personal discovery and exploration. To that end, 23andMe has an optional health upgrade that provides reports on DNA traits like hair color and genetic predispositions to certain illnesses and diseases. It is the only DNA test with FDA approval for testing genes linked to conditions such as Type 2 diabetes, certain types of cancer, late-onset Alzheimer’s disease and Parkinson’s disease. If you’re interested in the health portion of the test, we recommend buying the Health + Ancestry test together, as this option costs less than upgrading later.
Most direct-to-consumer DNA test companies warn that the tests may reveal things you wish you didn’t know about your family. For example, you could find out that one of the people who raised you isn’t your biological parent or that there’s an entire branch of your family you didn’t know about. There isn’t a way to prepare for a shock like that, but you can opt out of a company’s family-matching services if you’d rather not know.

Some concerns about the ultimate efficacy of certain home tests seem to emanate from the industry itself. I did a telomere-measuring test (a mouth swab) by Titanovo, based in north Colorado, which came back saying that my telomeres were too short, putting me at 10 biological years older than I am. However, when I contacted Titanovo, it explained that it had stopped telomere measuring and was now concentrating exclusively on its DNA-utilising “bioinformatics” health, fitness and wellbeing website (analysing client data from other genetic testing sites).
Specific tests for your father’s family include ‘Y-DNA’ tests which focus on the ‘Y chromosomes’ in your cells’ nuclei, passed down from father to son. Specific tests for your mother’s family include ‘mtDNA’ tests which report on a subset of DNA found in the ‘mitochondria’ (your cells’ energy factories), passed down from mother to son or to daughter.
