When most people think of Home DNA Tests, a paternity test is usually the first thing that comes to mind. Determining a child’s father can have important legal and personal ramifications.
But another reason for genetic testing is to determine risk factors for developing serious medical conditions. In addition, people who are interested in tracing their “genetic tree” have started purchasing Home Genetic DNA Tests in an attempt to discover their exact ethnic backgrounds.
According to Discover Magazine genetic tests are often based on SNPs (single nucleotide polymorphisms), which are common genetic markers shared by a group of individuals and can be used to calculate the genetic risk of developing complex diseases. Information is also provided about blood types and chromosomes. The average person may find out that they are at higher risk for celiac disease, diabetes or prostate cancer.
Most Home DNA Tests Kits provide information from swabs and do not require blood samples.
