General Information

  • Johns Hopkins DNA Diagnostic Laboratory (DDL) tests can be ordered through Epic
  • The general sample requirement is 3ml whole blood in lavender top EDTA tubes, but see our Sample Requirements for additional guidance
  • Order tests in Epic, but please complete a DDL requisition form and fax to the lab (410-367-3266) or send with the sample.
  • If you need targeted testing for a known mutation or prenatal testing, please contact the lab directly to coordinate at 410-955-0483 prior to obtaining the sample
  • For samples from the DGM Genetics Clinic ***JHG will pick up samples from CMSC 1004 on Tuesdays and Thursdays by 10AM.

  • If a sample is processed through the Core Lab, the Johns Hopkins DNA Diagnostic Laboratory is not involved in billing
  • The prices provided on our web site apply to outside referrals and do not necessarily reflect what your patient will be charged. If a sample is drawn in 'regulated space', Maryland law regulates the fees charged for laboratory services based on CPT codes, relative value units (RVUs), and the current RVU reimbursement rate. Neither the Johns Hopkins DNA Diagnostic Laboratory nor the Department of Pathology control the assigned RVUs or RVU rates. Please contact Pathology Customer Service at 5-1921 to find out the current fee for a test.
  • If the patient is uninsured, has a non-contracted insurance plan, or will be paying out of pocket for any other reason:
     
    • Have the patient sample drawn in non-regulated space to minimize out-of-pocket expense (see draw sites below) and do not order the test in Epic or process the sample through the Core Lab or Department of Pathology
    • Contact the Johns Hopkins DNA Diagnostic Laboratory for pricing information at 410-955-0483
    • Include credit card information or a check made out to Johns Hopkins University with the completed requisition form
