Genetic tests comprise analysis of human DNA, RNA, or protein. Genetic tests are known for early detection of a mutant or variant in the genome that is known to cause or contribute to a debilitating phenotype, or disease. However, recently companies are claiming that they can detect more than just disease based on genotype (genetic makeup), including future abilities and talents in young children, the age at which wrinkles will appear, the optimal diet for an individual, and no-fail quit-smoking plans. Certain claims lack substantial scientific backing and therefore the validity of those tests are questionable. The majority of genetic testing devices and kits can be found on the internet on the company website. Some companies advertise clinical tests directly to buyers. The major flaw inherent in this process is that consumers often put blind faith in the product and obtain clinically significant test results before consulting a physician, and therefore consumers do not have proper instruction in understanding or utilizing the testing results.
