What Is DNA Testing?
DNA testing is a type of medical test that identifies and characterizes changes in genes, chromosomes, or proteins within a human being. Specifically, it analyzes the genetic code carried in every person’s DNA and can be found in the cells of any human material, from a smear of blood to a strand of hair, or a drop of saliva. Simply put, DNA testing works by taking a sample of cells from an individual, and scientists isolate the DNA code at the core of every single cell carrying the information that determines your physical characteristics and the possibility of developing certain conditions. The results of a DNA test can confirm or rule out a suspected genetic condition and help an individual determine if they have a chance of developing or passing on a genetic disorder to their offspring.
