CBC (Complete Blood Count)
A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia.
A complete blood count test measures several components and features of your blood, including:
Red blood cells - which carry oxygen
White blood cells - which fight infection
Hemoglobin, the oxygen - carrying protein in red blood cells
Hematocrit - the proportion of red blood cells to the fluid component, or plasma, in your blood
Platelets - which help with blood clotting
Abnormal increases or decreases in cell counts as revealed in a complete blood count may indicate that you have an underlying medical condition that calls for further evaluation.
