iScreen Validity & Adulteration SVT / AD Test Strips by Alere # DUC-111

Adulteration Test Strips or Specimen Validity Test (S.V.T.) are a rapid, one step screening test for the simultaneous detection of Creatinine,
Nitrite, Glutaraldehyde, pH, Specific Gravity, and Oxidants/Pyridinium Chlorochromate (PCC) in human urine. They are an important pre-screening
test for any instant drug testing program. The instant drug Adulteration Strips are a fast dip-and-read test for the determination of diluted
or adulterated urine specimens.

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.

Note: This device is for forensic use only



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.”
Glutaraldehyde 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.
Nitrite 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.
Oxidants & PCC Tests for the presence of oxidants, such as bleach, hydrogen peroxide and Pyridinium Chlorochromate, in the urine.
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.
