Urine Adulteration Strips

Urine Temperature and Adulteration Strips

Donors may try to tamper with or manipulate a urine specimen with the intention of causing a false negative result. This is usually achieved by substitution or the addition of adulterants (including so called ‘masking agents’) that interfere with the screening test and/or destroy the drugs within the urine. Dilution may also be employed in an attempt to produce false negative drug test results.

One of the best ways to test for adulteration or dilution is to determine certain urinary characteristics such as pH and specific gravity and to detect the presence of oxidants/PCC, specific gravity, pH, nitrite, glutaraldehyde and creatinine in urine.

Some of our urine cups are equipped with integrated temperature and adulteration strips; however, you can also buy these separately for use with any of our urine tests.

Temperature strips

All samples should be recently voided (fresh) to ensure it has not been substituted or adulterated. The temperature of a specimen should be within the proper range of 33-38°C (91-100°F).
