Normal specific gravity range in urine The normal range of specific gravity in human urine is from 1.003 to 1.030. Values outside this range may be the result of specimen dilution, adulteration or may be indicative of a number of health related problems.hen looking at the results of a urine test (urinalysis test), specifically the results of the specific gravity urine test a person could deduce certain information regarding the health of the test subject. Any such deductions should be confirmed by further tests.
