Validity Screens and Adulteration Testing

 

      Drug Adulteration Strips
QED Test

The Instant Technologies Drug Adulteration Strips are a fast dip-and-read test for the determination of diluted or adulterated urine specimens. They are an important prescreening test for any drug testing program.

The one step dip and read specimen validity test semi-quantitatively analyzes a urine specimen for 7 parameters on 6 reactive pads in one easy step.

Creatinine - This test covers the most common form of specimen tampering, specimen dilution. Dilution using diuretics is also often referred to as “flushing”


Nitrites – This covers a class of chemicals not normally found in human urine. Common occurrences are the additive of such products as Klear.

Glutaraldehyde - This covers a class of chemicals not normally found in human urine. Common occurrences are the additive of such products such as Clear Choice or UrinAid.

pH – Tests for the presence of acidic or alkaline adulterants in urine

Specific Gravity – Tests for the viscosity of the urine sample

Oxidants and PCC – Tests for the presence of oxidizing reagents such as bleach, hydrogen peroxide and pyridinium chlorochromate

Results are obtained by comparing the color on each of the test pads with the corresponding pad on the container color chart label.
