Test Code CBC WDIF CBC With Differential, Blood
Methodology
Includes: WBC, RBC, hemoglobin, hematocrit, MCV, MCH, MCHC, RDW, platelets, MPV, and white cell differential and red cell morphology.
Note: A manual differential will be performed if established criteria is met or at doctor’s request.
Performing Laboratory
Decatur Morgan Hospital-Decatur Campus/Parkway Campus
Specimen Requirements
Specimen must arrive within 24 hours of draw.
Draw blood in a lavender-top (EDTA) tube(s) or a lavender-top (EDTA) MICROTAINER(S)®, and send 5 mL (minimum volume: 1 mL) of EDTA whole blood.
