1. Specimen was diluted - A urine specimen with creatinine and specific gravity values that are lower than expected for human urine.
2. Substituted Specimen - A urine specimen with creatinine and specific gravity values that are so diminished or incongruent that they are not consistent with normal human urine.
3. Adulterated Specimen - A urine specimen containing a substance that is not a normal constituent or containing an endogenous substance at a concentration that is not a normal physiological concentration.
