| Note: | Samples can be delivered to the Tissue Antigen Laboratory, Room 3.350J, Children's Hospital, Monday-Friday, 8 AM to 5:00 PM. Samples received after noon will be processed the next business day. Schedule 24 hours in advance. The request form must contain the following information: patient name, UH #, physician's name, route, and extension. |
| When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent. | |
