Quest Diagnostic’s highly specific diagnostic tests can help to avoid unnecessary follow-up testing and allow more accurate interpretation of depth of response to treatment. We have several successful ongoing projects with major pharmaceutical companies. Some of our work includes:

  • A new class of drugs, such as “checkpoint inhibitors,” which were recently approved by the FDA
  • Immunooncology
  • Personalized medicine

We also offer molecular testing to understand mutation status in diseases such as non–small cell lung cancer.
