Which elements on a standard CMP or other test could suggest dehydration?
Na, BUN, Creat
The three most important components on a comprehensive metabolic panel with respect to "hydration" are the Sodium or Na (This will be elevated with dehydration), The Blood Urea Nitrogen or BUN (This too will be elevated with dehydration) and the Creatinine or Creat.
In severe cases of dehydration, the creat can be elevated signifying kidney damage.
