CBC with Differential

The complete blood count (CBC) with 5-part differential is a comprehensive hematologic assay that quantifies circulating red blood cells, white blood cells, and platelets, along with several erythrocyte indices. The test includes measurement of red blood cell count (RBC), hemoglobin (Hgb), hematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), platelet count, and white blood cell count (WBC). The 5-part differential provides both absolute and relative counts of neutrophils, lymphocytes, monocytes, eosinophils, and basophils.CBC) with 5-part differential is a comprehensive hematologic assay that quantifies circulating red blood cells, white blood cells, and platelets, along with several erythrocyte indices.

This assay is used to evaluate anemia, infection, inflammation, immune disorders, hematologic malignancies, and other conditions affecting blood cell production or survival.
