Oxazepam BZO Drug Abuse Test Kit One Step OEM ISO13485 / CE In Whole Blood /Serum/Plasma
The BZO Rapid Test Cassette (whole blood/serum/plasma) is a lateral flow chromatographic immunoassay for the detection of Benzodiazepines in whole blood or serum or plasma at a cut-off concentration of 100ng/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 specif ic 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 BZO One Step Benzodiazepines Test Device is an immunoassay based on the principle of competitive binding. Drugs that may be present in the urine specimen compete against the drug conjugate for binding sites on the antibody.
During testing, a urine specimen migrates upward by capillary action. BZO, if present in the urine specimen below cut-off concentration, will not saturate the binding sites of the anti-bodiesin the test device. The antibody coated particles will then be captured by immobilized benzodiazepine conjugate and a visible colored line will show up in the test line region. The colored line will not form in the test line region if the BZO level exceeds cut-off concentration, because it will saturate all the binding sites of anti-BZO antibodies.
A drug-positive urine specimen will not generate a colored line in the test line region because of drug competition, while a drug-negative urine specimen or a specimen containing a drug concentration lower than the cut-off will generate a line in the test line region because of the absence of drug competition.
To serve as a procedural control, a colored line will always appear at the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.

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 Benzodiazepines 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 Benzodiazepines 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.
