Adulterants Survey, Random, Urine
Use
Assessment of possible adulteration of a urine specimen submitted for drug of abuse testing, including evaluation of creatinine concentration for normalization purposes, pH, specific gravity, presence or absence of oxidants, and presence or absence of nitrite. This aids in detecting manipulation of urine samples that may distort drug testing results. Reference cutoff concentrations: oxidants 200 mg/L, nitrites 500 mg/L. Uses creatinine for normalization.

Limitations
No significant cautionary statements were provided. Specimen adulteration detection may be influenced by interfering substances such as water, soap, bleach, vinegar, oxidants, and salt. Interpretation should follow the Adulterant Survey Algorithm. ([mayocliniclabs.com](https://www.mayocliniclabs.com/test-catalog/Overview/29345?utm_source=openai))
