Key points
- No current hydration measurement accurately reflects total body water (TBW) changes during daily activities.
- Plasma osmolality (P(osm)) has not been incontrovertibly demonstrated to represent TBW gain and loss.
- A single blood or urine sample is insufficient to represent fluctuating TBW and fluid compartments.
- Future research should focus on developing real-time, precise, accurate, reliable, non-invasive, portable, inexpensive, safe, and simple hydration assessment techniques.

Abstract
Acknowledging that total body water (TBW) turnover is complex, and that no measurement is valid for all situations, this review evaluates 13 hydration assessment techniques. Although validated laboratory methods exist for TBW and extracellular volume, no evidence incontrovertibly demonstrates that any concentration measurement, including plasma osmolality (P(osm)), accurately represents TBW gain and loss during daily activities. Further, one blood or urine sample cannot validly represent fluctuating TBW and fluid compartments. Future research should (a) evaluate novel techniques that assess hydration in real time and are precise, accurate, reliable, non-invasive, portable, inexpensive, safe, and simple; and (b) clarify the relationship between P(osm) and TBW oscillations in various scenarios.
