*Red cell distribution width; measure of variation in red blood cell size (anisocytosis)<br />
<br />
==Normal Values==<br />
*Normal: 11.5-14.5%<br />
<br />
==Interpretation==<br />
*Elevated RDW indicates variation in RBC sizes (anisocytosis)<br />
*Useful in distinguishing iron deficiency anemia (elevated RDW) from thalassemia trait (normal RDW)<br />
*Elevated in mixed-deficiency anemias, early iron/B12/folate deficiency, and transfused patients<br />
*Elevated RDW has been studied as a prognostic marker in heart failure, PE, and sepsis<br />
