Cell culture is the process by which cells from human tissue are grown in an incubator under controlled conditions in order to provide sufficient material for testing. The cells are grown in tissue culture flasks in a medium containing cell nutrients and growth factors. Once the cultures grow to a sufficient volume , DNA is then extracted to be used for requested genetic testing. Back-up cultures are maintained until testing is complete and reported in case further DNA is required to complete testing

A cell culture takes an average of 2 weeks before DNA is ready to be extracted; however, this timeline is highly dependent on the specimen size, quality, and the ability of the cells to grow.
- Maintaining a reserve DNA source for direct prenatal or tissue specimens.
- Collecting a quantity of DNA, that is otherwise difficult to secure from a direct specimen.
