Adulteration and Clinical External Controls

The instant drug Adulteration Strips are a fast dip-and-read test for the determination of diluted or adulterated urine specimens. They are an important pre-screening test for any instant 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.

pH Level: Tests for the presence of acidic and alkaline adulterants. Normal urine pH ranges from 4.0 to 9.0. Values below pH 4.0 or above pH 9.0 are indicative of adulteration.
Specific Gravity: Tests for sample dilution. Normal levels for specific gravity will range from 1.003-1.030. Specific gravity levels of less than 1.003 or higher than 1.030 is an indication of adulteration.
Oxidants and PCC: Tests for the presence of oxidants, such as bleach, hydrogen peroxide and Pyridinium Chlorochromate, in the urine.
Nitrate: Tests for the presence of exogenous nitrate. Nitrate level above 7.5 mg/dl in human urine is considered abnormal. Common occurrences are the additive of such products as Klear.
Glutaraledhyde: Tests for the presence of exogenous aldehyde. Glutaraldehyde is not a natural component of human urine and it should not be present in normal urine. Common occurrences are the additives of such products such as Clear Choice or UrinAid.
Creatinine: Daily creatinine excretion, related to muscle mass of the human body, is usually constant. Urine specimens with creatinine levels of less than 20 mg/dl are indications of adulteration. This test covers the most common form of specimen tampering, specimen dilution. Dilution using diuretics is also often referred to as “flushing.”

Controls are available in both positive and negative formats, and are used to demonstrate the results of urine based drug tests. A negative control will yield expected negatives on each panel, and the positive control will yield all positive results.

iScreen Drug Control Negative, 5 mL
iScreen Drug Control High Positive, 5 mL

The Q.E.D A150 Ethanol control is used as a performance control in the determination of alcohol in the saliva. The control contains an aqueous solution of ethanol with preservatives, and has an expected range of .075 to .130%.
