How to Read the iCup Drug Test Results
Test Results
NEGATIVE: Two lines appear. One red line should be in the control region (C), and another apparent
red or pink line adjacent should be in the test region (T). This negative result indicates that the drug
concentration is below the detectable level. *NOTE: The shade of red in the test line region (T) will vary, but it should be considered negative
whenever there is even a faint pink line.
POSITIVE: One red line appears in the control region (C). No line appears in the test region (T).
This positive result indicates that the drug concentration is above the detectable level.
INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques
are the most likely reasons for control line failure. Review the procedure and repeat the test using a new
test panel. If the problem persists, discontinue using the lot immediately and contact your manufacturer.
Adulteration Interpretation
pH: 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 are an indication of adulteration.
Oxidants: Tests for the presence of oxidants, such as bleach and peroxide, in the urine. Oxidants, when
present in the urine, will produce a blue or green color.
