A CBC must be ordered to perform a differential. Hematology instruments are automated differential screening instruments that identify WBC's by their size and staining activity. It performs a complete cell identification that includes neutrophils, lymphocytes, monocytes, basophils, eosinophils and immature granulocytes. The automated instruments count 32,000 white blood cells and statistically provide a more accurate differential count than a manual differential. All differentials will be analyzed on the instrument first. If the results fail the screening criteria, a manual differential will be performed. Pathologist approval is required to perform a manual differential on a specimen with an automated differential that passed the screening criteria.
This test is also performed in the Iowa River Landing (IRL) clinical laboratory (for specimens drawn at that site).
