  5. Model No:BZO-R02


The BZO Rapid Test Device (Saliva) detects Benzodiazepines through visual interpretation of color development on the Device. Drug conjugates are immobilized on the test region of the membrane. During testing, the specimen reacts with antibodies conjugated to colored particles and precoated on the sample pad. The mixture then migrates through the membrane by capillary action, and interacts with reagents on the membrane. If there are insufficient drug molecules in the specimen, the antibody-colored particle conjugate will bind to the drug conjugates, forming a colored band at the test region of the membrane. Therefore, a colored band appears in the test region when the urine is negative for the drug. If drug molecules are present in the urine above the cut-off concentration of the test, they compete with the immobilized drug conjugate on the test region for limited antibody binding sites. This will prevent attachment of the antibody-colored particle conjugate to the test region. Therefore, the absence of a colored band at the test region indicates a positive result. The appearance of a colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.

3. Results

NEGATIVE:Two lines appear.One colored line should be in the control region (C),and another colored line should be in the test region (T).This negative result indicates that the Benzoylecgonine concentration is below the detectable level (300 ng/mL).

NOTE:The shade of the color in the test region (T) may vary,but it should be considered negative whenever there is even a faint line.

POSITIVE: One colored line appears in the control region (C).No line appears in the test region.This positive result indicates that the Benzoylecgonine concentration is above the detectable level (300 ng/mL).

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 device.
