What is the Ancestry DNA Test?

The Ancestry DNA test utilizes the autosomal technology to help an individual uncover their family history. This technology helps predict genetic ethnicity using advanced DNA science and maps out ethnicity that can even go as far back as several generations. In doing so, this technology unravels complete genetic makeup of an individual giving history of origin, relations and even of health. This test also estimates and identifies any genetic matches, and thus linking people who are related but are in different geographical regions. For this reason, ancestry DNA test ancestry is important because of its insightfulness.

How the AncestryDNA test works

AncestryDNA uses micro-array based autosomal DNA testing by taking a saliva sample and comparing it with others in over 700,000 locations across the globe. This then produces a genome mapping that reveals any links and any history that exists. Unlike other tests, women and men can both take this test. This is because both genders carry the DNA that is being tested. Some tests only analyze the Y-Chromosome and others analyze the mitochondrial DNA. Ancestry DNA however uniquely analyzes an individual’s entire genome against a multitude of others, making it more effective and far reaching.

The reason that makes ancestry DNA test more suitable is that it is more comprehensive than any other test, and that it is gender neutral. Further, it predicts recent genetic ethnicity by comparing the sample with others around the world, and shows any matches that come up. This test also looks at the DNA broadly, not just the Y chromosome or the Mitochondrial DNA, and this is important because it enhances DNA matching in places where all the other methods may fail to do so. Other DNA testing methods only have a range of up to 50,000 year focus, but Ancestry DNA test goes further than that in checking for lineage and history.

Points to Note about Ancestry DNA testing

It is important to note that this test has a very high success rate, which goes up to 98%. This however may be impeded by several factors. If an individual has received a bone marrow transplant or a stem cell transplant, then they cannot take this test. This is because DNA is collected from an individual’s saliva sample which contains cells from multiple cells, for example blood cells that are created by stem cells. This saliva therefore may contain DNA from the donor’s stem cells or the donor’s bone marrow, whichever the case, and thus any DNA evaluation may be tainted. For this reason, anyone who has received such a donation is asked not to take the test, but a close relative, such as a parent or sibling, can take the test and the results will inherently be the same.

Another important point to note is that privacy is of paramount importance during this test. It is commonplace for many individuals to be concerned about the privacy of the DNA sample and the results. The test however has taken stern measures to ensure that privacy is maintained. DNA tests are conducted in secure locations, and the test results are owned and controlled by the owner. This information is only shared by the owner, and other users of the platform can only see these results if and only if the user invites them to, or shares the information.
