A Complete Blood Count (CBC) is one of the most commonly performed blood tests. It provides valuable information about the cells in your blood and helps detect a wide range of disorders.

What Does CBC Measure?

The CBC test measures several components:

• Red Blood Cells (RBC): Carry oxygen throughout the body
• White Blood Cells (WBC): Fight infections and diseases
• Hemoglobin (Hb): Protein in RBCs that carries oxygen
• Hematocrit (HCT): Percentage of blood volume made up of RBCs
• Platelets: Help blood clot and prevent bleeding

When Should You Get a CBC Test?

• Annual health checkup
• Unexplained fatigue or weakness
• Frequent infections
• Unusual bruising or bleeding
• Before surgery
• Monitoring chronic conditions

Understanding Your Results

Your doctor will interpret your CBC results in the context of your overall health. Abnormal results may indicate anemia, infection, inflammation, bleeding disorders, or blood cancers.
