Optimal RDW reference ranges for longevity

According to OptimalDX, RDW should be between 11 and 12.6 %
According to Tonelli M. et al. (2019), RDW should be between 11.4 and 12.6 %

High RDW was associated to substantial rise in all-cause mortality.

Red: adjusted for demographics; Blue: adjusted for demographics and all 30 baseline morbidities. Green: fully adjusted (demographics, morbidities, and baseline HGB, WBC, and eGFR.)
