Documentation of informed consent is required for all EPIC orders. The EPIC order composer requires a provider to confirm:

1. Whether the patient or their healthcare decision maker has been counseled about the benefits and drawbacks of the genetic test being ordered.
2. The provider has confirmed verbal or alternate written consent to order the test.
   
   

If consent has not been documented at the time of ordering, the provider is prompted to complete a consent supplement and submit it to the lab.

• Zoom, Targeted Variant, Maternal Cell Contamination
• Huntington Disease & Huntington Disease-Like 2

Orders without documented consent will not be initiated until consent is confirmed.

Questions about obtaining consent for genetic testing? Reference our handout or reach out to our genetic counselors.

In certain situations, transfusions and transplants can impact the accuracy of genetic test results. Blood and saliva are not acceptable specimen types if a patient has:

• Received blood products other than pRBCs within the last 2 weeks.
• Received an allogenic bone marrow or stem cell transplant. Cultured skin fibroblasts are the recommended specimen type.
• Active hematologic malignancy. Cultured skin fibroblasts are the recommended specimen type.

Review our Sample Requirements for information about collecting specimens from patients who have received a transfusion or transplant.

• JHG DDL will pick up samples from the Genetics Clinic on Tuesdays and Fridays.
• If you have proband or parental saliva samples to be picked up, please place the samples in the “Johns Hopkins Genomics – Sample Pickup” box that will be placed in the GC suite. Blood samples should be kept in the DDL bin in the refrigerator in the GC Suite. Samples from these two locations will be routinely picked up by a member of the JHG staff throughout the week.
• If you need saliva kits, please email your request to [email protected].

• If a sample is processed through the Core Lab, the JHG DDL 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 Genomics 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 JHG DDL for pricing information at [email protected].
  • Include credit card information or a check made out to Johns Hopkins University.
