About Our Complete Blood Count (CBC) with Differential

The Complete Blood Count (CBC) is one of the most commonly ordered blood tests and provides a broad overview of your overall health and blood function. It evaluates three major components of your blood: red blood cells, white blood cells, and platelets.

These components play critical roles in your body:

  • Red blood cells carry oxygen to your organs and tissues
  • White blood cells support your immune system and help fight infection
  • Platelets help your blood clot and support tissue repair

A CBC test can help identify early signs of conditions such as anemia, infection, inflammation, immune disorders, and blood-related abnormalities, often before symptoms become severe.

The test requires a small blood sample drawn from a vein in your arm and is frequently used for routine checkups, monitoring health conditions, or investigating unexplained symptoms.


What Is Included In This Test?

Red Blood Cell Measurements:

  • Red Blood Cell Count (RBC): Measures the number of red blood cells that carry oxygen throughout your body
  • Hemoglobin (Hgb): Measures the oxygen-carrying protein inside red blood cells
  • Hematocrit: Measures the percentage of your blood made up of red blood cells
  • Mean Corpuscular Volume (MCV): Measures the average size of red blood cells
  • Red Blood Cell Distribution Width (RDW): Measures variation in red blood cell size
  • Mean Corpuscular Hemoglobin (MCH): Measures the average amount of hemoglobin per red blood cell
  • Mean Corpuscular Hemoglobin Concentration (MCHC): Measures the concentration of hemoglobin in red blood cells

Together, these values help assess anemia, nutrient deficiencies, hydration status, and other blood disorders.

White Blood Cell Measurements:

  • White Blood Cell Count (WBC): Measures the total number of white blood cells
  • White Blood Cell Differential: Breaks down the five types of white blood cells to evaluate immune response:
    • Neutrophils
    • Lymphocytes
    • Monocytes
    • Eosinophils
    • Basophils

These values help detect infections, inflammation, immune disorders, and reactions to medications.

Platelet Measurements:

  • Platelet Count: Measures the number of platelets involved in blood clotting and tissue repair. Abnormal platelet levels may affect bleeding or clotting risk.

Who Should Consider This Test?

The Complete Blood Count test is appropriate for most adults and is often used as a first-line screening tool.

You should consider a CBC test if you:

  • Want a routine check of overall health
  • Are experiencing fatigue, weakness, dizziness, or shortness of breath
  • Have frequent infections, inflammation, or unexplained fevers
  • Notice easy bruising, prolonged bleeding, or abnormal bleeding
  • Have symptoms that may suggest anemia or immune issues
  • Are starting or monitoring medications that can affect blood counts
  • Have a chronic condition or want to track changes in blood health over time

A CBC test does not diagnose a specific disease on its own, but it provides essential information that helps guide further testing, medical evaluation, and treatment decisions.

If you are experiencing symptoms related to abnormal red blood cells, white blood cells, or platelets, a CBC test is a simple and effective first step toward understanding your health.
