(12PressRelease.com) With the modern popularity of Do-It-Yourself products available on the internet, you might question whether something as consequential as a paternity or an ancestry test should be trusted to be completed by yourself at home. There are clearly plenty of products purchasable: labs around the world offer testing services to hospitals, governmental agencies and corporations, many of whom retail DNA kits to prospective customers for between $50 and $150 - this does not incorporate the charge of having the dna specimen analyzed and the results sent back. So, cost aside, can these at-home kits be trusted? And, if so, under which circumstances should they be put into use?
A DNA Kit is merely as good as the laboratory doing the analysis, and testing (or profiling) know-how has evolved quite a bit since the 1980's. The most common analysis completed in North America, termed the PCR (polymerase chain reaction) test, is employed by the FBI and is able to render results that are above 99% accurate for cases such as paternity testing. It works by comparing particular regions of one's genetic profile (called loci) to the same regions in another's genome, and then using statistical analysis to decide whether or not the two samples both share inheritance patterns. Today's up-to-date laboratories now have the technical tools and equipment to precisely execute this test. When DNA samples are collected prudently and without contamination, which is certainly possible in a residential setting, home testing kits can give an equally high success rate.
Ancestral DNA testing compares one's genome to populations within a database. Due to the calculations involved, the results are entirely based on probabilities. With a choice between maternal and paternal lineage testing, people can uncover their "genetic roots": essentially statistical matches displaying how positively their DNA correlates with ethnic populations in diverse geographic regions across the globe. Ancestry testing kits are not available in patient-doctor contexts, are not covered by insurance, and are hardly ever used in legal processes. As a result, they are perhaps most desirable for Do-It-Yourself types who are interested in their lineage and might want to join a community of similar individuals.
The assorted types of DNA testing at one's disposal, such as sibling,maternity, avuncular (aunts, grandparents), and ancestry tests all carry distinct statistical accuracy percentages. For instance, testing whether two people are siblings, who might share at most one biological parent, will have a lower success ratio than proving whether two individuals are identical twins.
Determining whether an at-home DNA kit meets your needs depends on your preference for privacy and whether or not the results will be employed for legal means. Some sellers are now providing additional services and documentation to offer legally admissible test results. Additional important factors to look in to are the reliability of the company and the laboratories they work with. Certification by the AABB (American Association of Blood Banks), corroboration with the Better Business Bureau, and highly accessible customer-service options are also advocated. Once you are comfortable with the appropriate corporation, you can rest assured that the outcome of an at-home DNA testing kit should be just as reliable as if you had the test performed at a professional setting.
