The course of idiopathic pulmonary fibrosis (IPF) is characterized by variable patterns of disease progression. The red cell distribution width (RDW) is a parameter that is routinely reported with all CBC counts. We sought to test the prognostic usefulness of this parameter in a well-defined cohort of patients with IPF. ⋯ The RDW is a readily available laboratory test result that may provide important, independent prognostic information at baseline and follow-up in patients with IPF. Further studies are warranted to validate this as a biomarker for IPF outcomes, as well as to define the biologic basis for this association.
