Quest Diagnostics Joint Directory of Services

Our customized online Joint Directory of Services (JDOS™), App helps you communicate with your clients by giving you around the clock control over your blended test listing. Your clients can look up test codes, CPT codes, specimen requirements, reference ranges and clinical usage information to assist them in choosing the right test(s) for their patients. Get it via the Web, printed book or CD-ROM.

  • Web-based—we host and maintain the Website for you, all for a small, one-time fee.
  • Printed books or CD-ROM—you can also order printed JDOS books or CD-ROMs that your clients can use for a quick,tangible reference without having to access the JDOS Website.
