RDW

RDW is a clinical biomarker on the Blood panel, reported in %. Standard reference range: 11–15 %. Functional (optimal) range used by integrative practitioners: 11–12.6 %.

What is RDW?

Red cell distribution width (RDW) quantifies variability in red cell size (anisocytosis); elevation helps differentiate iron deficiency from thalassemia and signals mixed deficiencies.

How SomaVue interprets RDW

SomaVue maps every result for RDW against four clinical lenses — nutrient cofactors, toxin exposure, infection drivers, and circadian/hormonal context — and connects each interpretation to specific peer-reviewed citations. Pre-mapped clinical reasoning and cross-marker pattern detection are available inside the practitioner workspace.
