Adulteration and Clinical External Controls
ADULTERATION
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.”
CLINICAL EXTERNAL CONTROLS
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%.
