with each drug at 25% below and 25% above cutoff levels. Each sample was tested by three batches of the
corresponding drug of abuse test. Three laboratory assistants read the result per batch of the corresponding
drug of abuse test. The result demonstrates that varying range of PH do not interfere with the performance of
the test.
Interfering Substances
Clinical urine samples may contain substances that could potentially interfere with the test. The following
compounds were added to drug-free urine, urine with a drug concentration 25% below the cutoff, and urine
with a drug concentration 25% above the cutoff for the corresponding drug of abuse test. All potential
interferents were added at a concentration of 100 µg/mL. None of the urine samples showed any deviation
from the expected results.
