A Complete Blood Count (CBC) is a common blood test that provides a comprehensive overview of a person’s overall health and detects a variety of disorders, such as anemia, infection, and many other diseases. It measures several components of the blood, including:

1. Red Blood Cells (RBC) – Carry oxygen from the lungs to the rest of the body.
2. White Blood Cells (WBC) – Part of the immune system and help fight infections.
3. Hemoglobin (Hb) – The protein in RBCs that carries oxygen.
4. Hematocrit (Hct) – The percentage of blood volume made up of RBCs.
5. Platelets – Help with blood clotting and prevent excessive bleeding.
6. Mean Corpuscular Volume (MCV) – The average size of red blood cells.
7. Mean Corpuscular Hemoglobin (MCH) – The average amount of hemoglobin in a red blood cell.
8. Mean Corpuscular Hemoglobin Concentration (MCHC) – The average concentration of hemoglobin in a given volume of red blood cells.

The CBC is used to diagnose conditions such as anemia, infection, clotting disorders, and leukemia. It is often performed as part of routine health check-ups.
