There is one standard Complete Blood Count (CBC) test.
While the CBC test analyzes various components of blood, including different cell types, it is a singular, comprehensive diagnostic test. The test identifies and counts the 7 types of cells found in the blood, specifically red blood cells, neutrophils, eosinophils, basophils, lymphocytes, monocytes, and platelets, according to Mount Sinai. This analysis allows doctors to gather information about a patient's overall health and detect various medical conditions or track health over time.
Here is what the CBC test measures according to the provided Mount Sinai reference:
- Red Blood Cells (RBCs): These cells carry oxygen. The CBC counts the number of red blood cells and measures the hemoglobin in them.
- White Blood Cells (WBCs): The CBC counts the different types of white blood cells (neutrophils, eosinophils, basophils, lymphocytes, and monocytes), which help fight infections.
- Platelets: These cell fragments help with blood clotting. The CBC counts platelets.
Therefore, while the CBC analyzes multiple parameters, it is a single test, not multiple tests. It provides a broad overview of a patient's blood composition.
