Important Note

This orderable is only to be used by Cardio Thoracic Surgery (CTS) for presurgical screening. A CBC with differential will be peformed and if the Hemoglobin is less than 13.0 mg/dL, a reflex test for Reticulocyte, Ferritin, Iron Profile, and Vitamin B12 will be performed.

Additional Codes

LAB10110 will generate a label for a conditional mint green (lithium heparin) tube.
