5ng/ml BUP Drug Abuse Rapid Testing Kit Buprenorphine 99% Specificity In whole blood/serum/plasma
The BUP Rapid Test Cassette (whole blood/serum/plasma) is a lateral flow chromatographic immunoassay for the detection of Buprenorphine in whole blood or serum or plasma at a cut-off concentration of 5ng/ml. This test will detect other related compounds, please refer to the Analytical Specificity table in this package insert.
This assay provides only a qualitative, preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
The One Step BUP Test includes a chromatographic absorbent device in which the drug in the sample compete with a drug conjugate immobilized on a porous membrane for limited antibody sites.
Labeled antibody-dye conjugate mixes with sample specimen and binds to the free drug present forming an antibody-antigen complex. This complex competes with immobilized antigen conjugate in the test zone preventing the formation of a pink-rose color band when the drug concentration in the specimen is above 10ng/ml. Unbound dye conjugates bind to the reagent in the negative control zone and produces a pink-rose color band, demonstrating that the reagents and device are functioning correctly.
A negative specimen produces two distinct color bands in both the test region and the control region. A positive specimen produces only one color band in the control region.

INTERPRETATION OF RESULTS
(Please refer to the illustration above)
NEGATIVE:* Two lines appear. One colored line should be in the control line region (C), and another apparent colored line should be in the test line region (T). This negative result indicates that the Buprenorphine concentration is below the detectable cut-off level.
*NOTE: The shade of color in the test line region (T) may vary, but it should be considered negative whenever there is even a faint colored line.
POSITIVE: One colored line appears in the control line region (C). No line appears in the test line region (T). This positive result indicates that the Buprenorphine concentration exceeds the detectable cut-off 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 with a new test. If the problem persists, discontinue using the test kit immediately and contact your local distributor.
