A blood count, also known as a complete blood count (CBC), is a laboratory test that measures the number of different types of cells in your blood. It is used to detect a wide range of conditions, including anemia, infection, and leukemia.
A blood count is a simple and relatively inexpensive test that can provide valuable information about your overall health. It is typically performed as part of a routine physical examination or when you are experiencing symptoms such as fatigue, weakness, or shortness of breath. The results of a blood count can help your doctor diagnose a medical condition and determine the best course of treatment.
