Mandatory Information

Laboratory Services will be performed at the written or electronic order of a physician or authorized practitioner.
A written or electronic request must be presented at the Laboratories’ Patient Service Center. The request must contain all of the following information:

  • Patient’s full first and last name
  • Attending physician name (if different from ordering physician)
  • Date of birth
  • Service(s) requested
  • Identification number (if available)
  • Diagnosis (ICD9) code for clinical indications for request; i.e. signs, symptoms, diagnosis
  • Ordering physician/practitioner name and signature. Eelectronic signatures usually contain date and timestamps and include printed statements (e.g., 'electronically signed by' or 'verified/reviewed by') followed by the physician’s / practitioner’s name and professional designation.)
  • Office/clinic Location
  • For non-OSU office/clinic: Fax number for results delivery
  • For non-OSU physicians/practitioners: NPI number also required

Per OSUWMC Medical Staff Administrative Policy, requests for laboratory services for outpatients that do not include ordering physician/practitioner signature or diagnosis information will not be processed until such information is obtained from the ordering physician/practitioner.

Patients are generally seen in the order they arrive at the patient service center unless they have a prescheduled appointment for a tolerance test.
