Comments

Pathologist approval is required for weekend, evening/late night and holiday STAT requests. This assay is used for all patients, regardless of age. Results will be affected if the patient has been transfused with red blood cells within the past 3-4 months. Provide patient's clinical history including newborn screen report from Ohio Department of Health, if available. Reflexive testing may include a CBC (CPT 85027), Sickle Solubility Screen (CPT 85660), and/or Acid Agar Electrophoresis (CPT 83020)ordered by the Pathologist for confirmation of diagnosis. A Pathologist's consult (billed from Pediatric Pathology Associates (PPAC)) will be ordered and charged to the patient if results are abnormal. A Pathologist's consult/interpretation may extend the expected turnaround time.
