What is a "Red Cell Distribution Width blood test"?

The Red Cell Distribution Width blood test (RDW blood test) measures the difference in size of red blood cells in a blood sample. This test helps evaluate the overall health of red blood cells and can be used to diagnose and monitor different types of anemia and other blood disorders. A high RDW suggests that the red blood cells are very different in size, which may be a sign of anemia or other conditions. A normal RDW means that the red blood cells are similar in size. And a low RDW, may be a sign that the red blood cells are unusually similar in size, which can be seen in certain types of anemia or other health conditions.
