Answer:
A complete blood count (CBC) is a common blood test that provides information about the level of formed elements in a person's blood.
Step-by-step explanation:
A CBC typically includes measurements of several components of blood, including red blood cells (RBCs), white blood cells (WBCs), and platelets. The test provides information about the number, size, and shape of these formed elements, as well as other parameters such as hemoglobin and hematocrit levels.
The RBC count and hemoglobin level in the CBC provide information about the amount of oxygen-carrying capacity of the blood, while the WBC count can indicate the presence of infection or inflammation. The platelet count can provide information about the ability of the blood to clot properly.
A CBC is a routine test that may be ordered as part of a regular check-up, to monitor a known medical condition, or to diagnose a new health problem. It is a simple and relatively inexpensive test that can provide valuable information about a person's overall health and well-being.
