CBC Assay

Tests done from CBC

Hematocrit (Hct) values correspond to the red cell count and hemoglobin level; when decreased, it indicates anemic conditions
Hemoglobin (Hgb) decreased values indicate anemic conditions; values normally differ with age, sex, altitude, and hydration
Red Blood Cell Count (RBC) measure of erythropoietic activity; decrease in numbers is related to anemic condition
White Blood Cell Count (WBC) abnormal leukocyte response indicative of various conditions, such as infections and malignancies; when accompanied by WBC, differential test becomes more specific
Platelet Count (Plt Ct) decreased number indicative of hemorrhagic diseases; values may be used to monitor chemotherapy or radiation treatments
Differential White Count (Diff) changes in appearance or number of specific cell type signifies specific disease conditions; values also used to monitor chemotherapy and radiation treatments
Indices changes in RBC size, weight, and Hgb content indicate certain types of anemias
Mean Corpuscular Hemoglobin (MCH) reveals the weight of the Hgb in the cell, regardless of the size; decreased Hgb content indicative of iron deficiency anemia; increased Hgb content found in macrocytic anemia
Mean Corpuscular Value (MCV) reveals the size of the cell; decreased MCV is associated with thalassemia and iron deficiency anemia; increased MCV is associated with folic acid or vit. B12 deficiency and chronic emphysema
Mean Corpuscular Hemoglobin Concentration (MCHC) reveals the Hgb conc. per unit volume of RBCs; < normal means red cells are deficient in Hgb as in thalassemia, overhydration, or iron deficiency anemia; > normal range will be seen in severe burns, prolonged dehydration, and hereditary spherocytosis
Red Blood Cell Distribution Width (RDW) reveals the size differences of the RBCs; an early predictor of anemia before other signs and symptoms
