INDICATORS OF HYDRATION STATUS
Urine color chart. The use of urine color, as measured using a urine color chart, can be helpful in monitoring hydration status. The urine color chart has eight standardized colors, ranging from pale straw (number 1) to greenish brown (number 8). Urine that is the color of pale straw usually indicates a normal hydration status; as urine darkens, poorer
hydration may be indicated (after the effect of discoloration by food or medications has been ruled out). I have recommended that for older adults, a reading of less than 4 on the color chart is preferred.
