Tests done from CBC
| Question | Answer |
|---|---|
| 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 |
