(BZO) Benzodiazepine Test 









Note:Could be customized under your request


  1. High sensitivity, simple, easy.
  2. Accuracy: >99%.
  3. CE & ISO approved.
  4. Specimen: Urine.
  5. Model No:BZO-U02B


The BZO Rapid Test Device (Urine) 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.

2. Usage:
Allow test device,urine specimen,and/or controls to equilibrate to room temperature (15-30°C) prior to testing.

  1. Bring the pouch to room temperature before opening it.Remove the test device from the sealed pouch

       and use it as soon as possible.

  2.  Place the test device on a clean and level surface.Hold the dropper vertically and transfer 3 full drops of urine
       (approx.100mL) to the specimen well (S) of the test device, and then start the timer.Avoid trapping air bubbles 
       in the specimen well (S).See the illustration below.

  3. Wait for the colored line(s) to appear.The result should be read at 5 minutes.Do not interpret the 
      result after 10 minutes


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.
