CBC Blood Test

A Complete Blood Count (CBC) is a common blood test that provides important information about the cells in your blood. It is often used as a general health check-up and to diagnose various medical conditions, such as infections, anemia, and blood disorders.

Measurement By CBC

A CBC test evaluates different components of your blood, including:

1. Red Blood Cells (RBCs) – Carry oxygen from the lungs to the rest of the body.
2. White Blood Cells (WBCs) – Help fight infections and immune responses.
3. Hemoglobin (Hb or Hgb) – A protein in RBCs that carries oxygen.
4. Hematocrit (Hct) – The percentage of blood volume occupied by RBCs.
5. Platelets (PLT) – Help in blood clotting to prevent excessive bleeding.

CBC is Done For

✔monitor overall health
✔ Detect infections or inflammation
✔ Diagnose anemia or leukemia
✔ Check for clotting disorders
✔ Assess the effectiveness of ongoing treatments

Test is Done By Blood Sample

A small blood sample is drawn from a vein, usually from the arm. The sample is then analyzed in a lab to measure blood cell counts and characteristics.

• Fatigue
• Swollen lymph nodes

2. Symptoms of Anemia (Low Red Blood Cell Count or Hemoglobin)

• Fatigue or weakness
• Dizziness or lightheadedness
• Shortness of breath

• Frequent nosebleeds
• Heavy menstrual bleeding
• Easy bruising

• Excessive bleeding (low platelets)
• Blood clot formation (high platelets)

6. Monitoring Chronic Conditions

• If you have conditions like leukemia, kidney disease, or autoimmune disorders, doctors may recommend regular CBC tests to monitor changes in your blood cell levels.

If you’re experiencing any of these symptoms, a CBC test can help your doctor diagnose the cause and guide further treatment.
