with the sample attached to the Path 3 form.

a sample is processed through the Core Lab, the DNA
Diagnostic Lab 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 DNA Diagnostic Lab nor the Department of
Pathology control the assigned RVUs or RVU rates. Please contact
Pathology Customer Service (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

pricing information: 410-955-0483
- Include credit card
information or a check made out to Johns Hopkins University with
the completed requisition form.
