The range for specific gravity in a normal urine specimen is greater-than-or-equal-to 1.003. The range of creantinine in a normal urine specimen is greater-than-or-equal-to 20mg/dl. If BOTH the specific gravity and the creatinine levels fall below the normal range, the specimen is considered dilute.
