is a complete blood count or CBC. Within a CBC, one important component of the test is known as the RDW or red cell distribution width test. This test provides valuable information related to the average size and variability of the red blood cells or RBCs in the body.

A normal RDW result ranges from 11-15% with anything outside of this range indicating a potential problem. Generally, a high RDW indicates a varied population of red cells, which can be a sign of anemia, or too few healthy RBCs. A low RDW can suggest either a macrocytic or less healthy population of larger RBCs or a microcytic population of smaller RBCs.

While the results may provide useful information related to any potential health problems, there are some positive benefits to having an RDW test done.

One benefit is that it allows medical professionals to confirm a diagnosis. In many cases, an anemia diagnosis requires a railing of an RDW in order to be completely confirmed. This can significantly help a doctor in treating any possible disorders associated with anemia.
