Erythrocyte distribution width Auto RBC Ratio
RDW measures how varied your red blood cells are in size. High variability (a higher RDW) can signal nutrient deficiencies like iron, B12, or folate—even before other markers go out of range. It’s often an early clue that oxygen delivery, energy metabolism, or red blood cell production is under stress. Inflammation, oxidative stress, or poor recovery can also drive it up. A quiet but powerful health signal.
