Description
A CBC provides a “snapshot” of your overall health by measuring the kind and number of cells in your blood. This test can help detect infections, anemia, immune system disorders, and other health conditions.
Components of the CBC with Differential and Platelets
White Blood Cells (WBC): The body’s primary defense against infections and disease.
Red Blood Cells (RBC): Carry oxygen and carbon dioxide to and from cells. Low levels may indicate iron deficiency.
Hemoglobin (Hgb): A protein in red blood cells that transports oxygen throughout the body. Gives blood its red color.
Hematocrit (Hct): Measures the proportion of red blood cells in blood, reported as a percentage.
Differential White Blood Cells:
- Neutrophils: Fight infections and inflammation.
- Lymphocytes (B-cells & T-cells): Help fight bacteria and viruses.
- Monocytes: Work with neutrophils to clear dead or damaged cells and fight infection.
- Eosinophils: Activated during allergic reactions and certain infections.
- Basophils: Detect infections early, aid in wound healing, and respond to allergens.
Red Blood Cell Indices:
- Mean Corpuscular Hemoglobin (MCH): Average hemoglobin per red blood cell.
- Mean Corpuscular Hemoglobin Concentration (MCHC): Average hemoglobin concentration percentage per red blood cell.
- Mean Corpuscular Volume (MCV): Average size of red blood cells.
- Red Cell Distribution Width (RDW): Variation in size and volume of red blood cells.
Platelets: Help form blood clots to prevent bleeding.
Absolute Counts:
- Absolute Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils: Measures the exact number of each white blood cell type to help identify abnormalities.
Fasting: Not required.
