    loss and fluid intake. For example‚ the loss of fluid through heavy sweating in hot weather reduces urine amounts. The minimum volume of urine needed to remove body wastes from an adult is about 500mL/day. The specific gravity of urine can be an indicator of disease or disruption in normal metabolism. As you recall from our earlier discussions‚ specific gravity measures the concentration of dissolved solids in a liquid without indicating what those solids are in the past‚ hydrometers were used to
