What does a CBC test typically assess?

A Complete Blood Count (CBC) test primarily assesses blood cell health. This includes the measurement of various components such as red blood cells, white blood cells, and platelets.

Red blood cells are evaluated for their number, size, and hemoglobin content, which are crucial for oxygen transport throughout the body. Anemia, for example, can be diagnosed through a decrease in red blood cell count or hemoglobin levels.

White blood cells, on the other hand, are an essential part of the immune system. The CBC provides information on their numbers and types, which can help identify infections, inflammation, and various other conditions, including blood cancers.

Additionally, the platelet count is also assessed in a CBC, which is vital for blood clotting. Abnormalities in platelet counts can indicate a risk for bleeding disorders or excessive clotting issues.

Therefore, the CBC serves as a fundamental test in evaluating overall blood health and detecting various diseases related to the blood components. It does not assess heart function, kidney function, or liver health directly, as these require different specialized tests.
