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.
We have several patients whose DNA was stored and later tested after they passed away, with important benefits to their relatives. In a family, genetic testing should be done on DNA from a relative who had the hereditary illness.
Genetic discoveries are continuously being made and DNA banking for future testing could be very beneficial for one’s relatives.
