Most often, DNA testing sites are used when a home DNA test kit will not suffice.  If you wish to find out about inherited disorders, Native American bloodlines, or you want to know if your twins are identical or fraternal, a home DNA test will provide you with answers.

Home kits are also used to settle issues involving paternity; however the results will not be admissible in a court of law because there is no proof of the origin of the sample. In cases where child custody and child support are being determined, an authenticated document called Chain of Custody must be obtained and that comes from a laboratory.

When an alleged father seeks proof of paternity, he enters an accredited lab, shows proof of identification and gives a DNA sample in the form of a cheek swab with a worker present.  Results can be expected within 3 to 5 days.  The lab report is legal.

Testing centers do other kinds of DNA analysis as well.  They can test samples within a family applying for visas with the U.S. Department of Immigration to show proof that each member of an alleged family is indeed related.

Some Native Americans wish to identify the clans they are associated with.  There are four ancient clans responsible for the Native populations today.  There are testing centers across the country, some located within close proximity to Reservations, so Native Americans can get the peace of mind they seek.

You’ll want to choose a laboratory that has earned  accreditation such as the American Association of Blood Banks, or AABB, and the ISO, the International Standards Organization. As DNA tests are not considered a medical necessity they are not covered by insurance, so shop around when looking for DNA testing sites to find one with reasonable prices.
