The Center for Medical Genetics offers individuals the opportunity to save their DNA, obtained from a blood draw, through DNA banking. DNA is extracted from an individual's white blood cells and stored indefinitely by freezing the DNA.
In most cases, genetic testing must first be done on the relative affected with the hereditary illness. Once the genetic alteration is found, other relatives may be tested and receive clear-cut results.
We have several patients whose DNA was stored and later tested after they passed away, with important benefits to their relatives. Genetic discoveries are continuously being made and DNA banking for future testing could be very beneficial for one’s relatives.
