Adulteration

What is adulteration?

When a person tampers with a urine specimen with the intention of altering drug or alcohol test results, this is known as adulteration.

Household chemicals such as bleach, table salt, laundry detergent, toilet bowl cleaner, vinegar, lemon juice, and eye drops are used for adulterating urine specimens.

Some people drink lots of water to dilute their sample and mask the level of drugs.

Most of these adulterants can be detected by routine specimen integrity tests (creatinine, pH, temperature, and specific gravity). In the case of water in a urine test, the change in specific gravity will flag to the collector that the person being tested has tried to mask substance levels.

The One Step S.V.T. is a semi-quantitative, colour comparison screen for the detection of creatinine, nitrite, glutaraldehyde, pH, specific gravity, and oxidants/pyridinium chlorochromate (PCC) in human urine. This test provides a preliminary screen only.

A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Abnormal results should be sent to a laboratory for confirmation.

Each of the plastic strips contains six (6) chemically treated reagent pads. One (1) minute following the activation of the reagent pads by the urine sample, the colours that appear on the pads can be compared with the printed colour chart on the canister. The colour comparison provides a semi-quantitative screen for creatinine, nitrite, glutaraldehyde, pH, specific gravity, and oxidants/pyridinium chlorochromate (PCC) in human urine, which can help assess the integrity of the urine sample.
