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.
