PERFORMANCE CHARACTERISTICS
A. Accuracy
The accuracy of the K2 Rapid Test Device (Urine) was compared and checked against commercially available tests with a threshold value at the same cut-off levels. Urine samples taken from volunteers claiming to be non-users were examined under both tests. The results were >99.9% in agreement.
B. Reproducibility
The reproducibility of the K2 Rapid Test Device (Urine) was verified by blind tests performed at four different locations. Samples with K2 concentrations at 50% of the cut-off were all determined to be negative, while samples with K2 concentrations at 200% of the cut-off were all determined to be positive.
C. Precision
Test precision was determined by blind tests with control solutions. Controls with K2 concentrations at 50% of the cut-off yielded negative results, and controls with K2 concentrations at 150% of the cut-off yielded positive results.
D. Specificity
The following tables list the concentrations of compounds (ng/mL) above which the K2 Rapid Test Device (Urine) identified positive results at 5 minutes.

LIMITATIONS
ACCU-TELL® K2 Rapid Test Cassette (Urine) is for professional in vitro diagnostic use, and should be only used for the qualitative detection of K2.
This assay provides a preliminary analytical test result only. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) has been established as the preferred confirmatory method by the National Institute on Drug Abuse (NIDA). Clinical consideration and professional judgment should be applied to any test result, particularly when preliminary positive results are indicated.
There is a possibility that technical or procedural errors as well as other substances and factors may interfere with the test and cause false results.
Adulterants, such as bleach and/or alum, in urine specimens may produce erroneous results regardless of the analytical method used. Therefore, please preclude the possibility of urine adulteration prior to testing.
A positive result indicates the presence of a K2 only, and does not indicate or measure intoxication.
A negative result does not at any time rule out the presence of K2 in urine, as they may be present below the minimum detection level of the test.
