Is it possible to have urine specific gravity of 1000?

A urine specific gravity of 1000 is at the low end of the normal range, indicating very dilute urine, similar to the density of pure water. This could occur in conditions like excessive hydration or certain medical conditions such as Diabetes insipidus. Typically, normal urine specific gravity ranges from about 1.005 to 1.030, so a reading of 1000 is unusual and may warrant further investigation if observed.
