DNA testing centers not only provide DNA analysis and testing services such as paternity testing and DNA banking but also offer counseling for researching biological relationships. These centers process samples through accredited laboratories for determining biological relationships and giving highly accurate test results. Some of the popular DNA testing centers are GeneTree, Childsafetyaid, DNA Testing Center of America and Atlanta DNA Center Inc., among others. Most DNA testing centers in the US provide general as well as specialized DNA testing services like Personal and Legal DNA Relationship Testing, mtDNA Analysis and Y-chromosome Testing, Forensic DNA Testing Services, DNA Identification System, Archiving Genomic Information, etc. Some testing centers also have interactive websites, wherein a consumer can access easy-to-use online order forms from the comfort of his home or office. Some testing centers also provide convenient, customer-friendly at-home collection kits free of charge. DNA testing centers generally use a combination of different STR markers to definitively measure biological relationships. These not only give reliable results, but can also measure distant biological relationships such as first cousin and grandparentage. Most DNA testing results are released within a weeks time, and the client can access the results immediately. However, when selecting a DNA testing center, it is essential to check a few facts, like whether the service offered by the center is globally recognized, whether the test results are reliable, whether the results can be admissible in a court of law, whether the center employs genetic experts, whether the operational aspects are supervised by an experienced and qualified management team, etc. Genetic tests are increasing in number for detecting disease or risk of disease, and understanding human genes and their influence on diseases. To understand the connection between genes, ancestry and health, most DNA testing centers are constantly developing new DNA analysis technologies. |
