Gene testing is a process of examining one’s DNA by taking a sample from cells in the blood. The cells may also be found in body fluids and tissues. Changes in the genetic material may be known through the use of genetic testing. It finds out is there are missing or additional chromosome through microscopic testing. Alteration of genes may also be known. In general, genetic testing the use of biochemical experimentation to find the presence or absence of normal genetic material found in one’s DNA. Disorders may be known and diagnosed.
