Observational study compares blood volume and bioimpedance in extreme body types, suggesting individualized fluid management approaches.

This study aims to compare blood volume and bioimpedance measurements in dialysis patients with extreme body types.
Defined obese, bioimpedance-dry and lean, bioimpedance-wet groups, alongside controls with normal volume status.
Compared post-dialysis blood volume at target weight using dialysate dilution.
Explored normalization of blood volume by body mass, lean tissue mass, and Lemmens' formula.
Obese/dry group had lower normalized blood volume (57.9 mL/kg) compared to controls (68.0 mL/kg; P = 0.02).
Lean/wet group had higher normalized blood volume (84.5 mL/kg) than controls (P = 0.001).
Normalization by body mass showed differences by sex and body mass, while Lemmens' normalization did not.

Keane et al. (2026) studied this question.
