CBC (Complete Blood Count) Test: A Complete Guide

What is a CBC test?

A Complete Blood Count, or CBC, is a routine blood test that measures the different components of your blood — red blood cells (RBCs), white blood cells (WBCs), platelets, hemoglobin, and hematocrit. It's often one of the first tests a doctor orders because it gives a broad snapshot of your overall health.

Why do doctors recommend a CBC?

A CBC helps detect a wide range of conditions, from anemia and infections to clotting disorders and certain blood cancers. It's commonly included in annual health checkups because it can flag issues even before other symptoms appear.

• Unexplained fatigue or weakness
• Frequent infections or slow healing
• Unusual bruising or bleeding
• Routine annual health checkups
• Monitoring an existing condition or treatment

What do the results show?

Your CBC report typically breaks down RBC count, WBC count, platelet count, hemoglobin level, and hematocrit percentage. Each lab includes a reference range alongside your result, so you can see whether a value falls within the expected range. It's best to review your report with a doctor, since normal ranges can vary slightly by age, sex, and lab.
