Test Code LAB0204586 Peripheral Blood Smear Morphology (Includes CBC with Differential)

Methodology

Coulter VCS Technology
Includes WBC, RBC, hemoglobin, hematocrit, MCV, MCH, MCHC, RDW, platelets, MPV, and 5-part screening differential.
Useful for screening, diagnosing, and monitoring of patients in the areas of allergic reaction, bleeding, hematopoiesis, and inflammatory response.
Note: If automated differential is rejected by the instrument, a manual differential is performed at no additional charge by manual microsopy.
