So What Do These DNA Testing Centers Do?
With DNA testing gaining fast popularity, it is imperative that these tests are performed at facilities which provide these niche services. DNA Testing centers must have sufficient expertise to do Blood Typing, DNA sampling, Analyzing the DNA and more importantly study of the DNA. My analysis of a cross-section of the DNA testing centers in New York City told me that each of these DNA Testing centers had the necessary expertise and experience to do all of the above mentioned functions. When I did a cross-country sampling, the results were not too different leading me to believe that DNA Testing centers are focal to the entire process of DNA Testing. So what do these DNA Testing Centers do? They study the DNA patterns of individuals who had requested DNA Tests to be done and provide the users with the results of their analysis. The study of the DNA will involve study of certain DNA regions which are found repeating across a majority of human beings. Certain tests requested by people will involve studying of multiple samples.
For example, if a person requests DNA Paternity testing, the DNA Testing center might have to adopt an analysis approach which is suited to give results for the Paternity Testing. Should you require a Maternity testing done, rest assured that the Testing center will take a different approach. The reason why the tests are so different is because of the fact that the chromosomes in a male and female are slightly different. A male has both the Mitochondrial DNA and Y-DNA whereas a female has only the Mitochondrial DNA. Hence, in most of the tests that the DNA Testing center conducts, samples from the male participant in the test is extremely important. Most of these testing centers also correlate their DNA Test results to provide you with your Haplogroup which shows the closest geographic group which shares your DNA. In order to refine the Haplogroup results, some testing centers can also provide you with the subgroup of the haplogroup. These results can generally be obtained if a person chooses to use the DNA Ancestry Testing Service. These testing centers maintain active databases of DNA profiles. They would require to search these databases to match DNA profiles with the profile of the person who has requested the service. Many tests like GrandParentage test, Twin Zybology test, Ancestry test requires the Testing centers to match the DNA profiles with the database to provide accurate results. With most of these centers providing 99% accuracy and more in their results, you should go ahead and choose one of these testing centers to get a DNA Testing done, if you need. |
