The Complete Blood Count (CBC) test is a common blood test used to evaluate overall health and detect a variety of disorders, such as infections, anemia, and other blood-related conditions. Here's an overview of the test.

Red Blood Cells (RBCs): These cells carry oxygen from your lungs to the rest of your body. The CBC measures the number and quality of red blood cells, which can indicate anemia, dehydration, or other conditions.

White Blood Cells (WBCs): These cells are part of the immune system and help fight infection. A CBC will measure the number of white blood cells to help detect infections, inflammation, or immune system disorders.

Hemoglobin: This protein in red blood cells carries oxygen. A low hemoglobin level often indicates anemia, while a high level might suggest other conditions, like polycythemia.

Hematocrit: This measures the proportion of red blood cells in the blood. It’s another indicator used to assess anemia, dehydration, or other conditions.

Platelets: Platelets are small blood cells that help with clotting. A CBC can detect abnormal platelet counts, which can indicate clotting disorders or other blood diseases.
