CBC Test: Purpose, Procedure, and Importance
Doctors often recommend this test to diagnose infections, anemia, and other medical conditions.

The Complete Blood Count CBC Test is a common blood test that provides essential information about overall health. It measures different components of blood, including red blood cells (RBCs), white blood cells (WBCs), platelets, hemoglobin, and hematocrit levels. Doctors often recommend this test to diagnose infections, anemia, and other medical conditions.
What is the CBC Test?
The CBC Test is a blood test that evaluates the following key components:
-
Red Blood Cells (RBCs): Carry oxygen throughout the body. Abnormal levels may indicate anemia or dehydration.
-
White Blood Cells (WBCs): Help fight infections. A high or low count can indicate infection, inflammation, or immune system disorders.
-
Hemoglobin (Hb): The protein in RBCs that carries oxygen. Low hemoglobin levels may suggest anemia.
-
Hematocrit (Hct): Measures the percentage of RBCs in the blood. Abnormal levels may indicate blood disorders or dehydration.
-
Platelets: Help in blood clotting. Low platelet count can cause excessive bleeding, while a high count may indicate clotting disorders.
