Clinical DNA Testing

Our CLIA and ISO 15189-accredited lab offers NextGen sequencing or Sanger sequencing for over 1,800 genes. Deletion/duplication testing via aCGH or MLPA is available for over 1,500 genes. PreventionGenetics has the largest DNA test menu of any lab in America.

PreventionGenetics has been in operation since 2004. We have grown steadily over this time, and now have the largest germline DNA test menu of any lab in America. The quality of DNA testing at PreventionGenetics is second to none. "Getting the tests right" has always been our first priority.

PreventionGenetics is CLIA accredited through CAP. Our quality assurance processes, however, far exceed regulatory requirements. For example, we have had to date one error out of 8,800 total Proficiency Tests, both external and internal. Our sequencing error rate is about one per 4.2 million nucleotides or one per 1600 sequence variants. Other summary measures of quality are listed in the "About Us" section of the web site.

Utilization Management

Teamwork Increases the Value of Genetic Testing

Utilization management is a current topic of particular interest in the realm of genetic testing. For many hospitals and health systems, the cost of sending out genetic tests is high (often > $1 million per year) and increasing at an annual average rate of about 20% (PLUGS©). Through utilization management strategies at PreventionGenetics, over 1.3 million healthcare dollars are saved annually.

DNA Banking

A Valuable Gift for Your Family

DNA Banking is the simple and affordable process of securely storing of an individual's DNA for use by the next generation for possible future testing. DNA can be banked at any time during a person's life but it is particularly urgent for the elderly and terminally ill. Once a person is cremated, it is not possible to obtain a DNA sample.
