INTENDED USE:The One-Step BAR Test is a lateral flow, one-step immunoassay for the qualitative detection of barbiturates, primarily secobarbital, in human urine at a cut-off of 300ng/ml. This product is used to obtain a visual, qualitative result and is intended for professional use.The assay should not be used without proper supervision and is not intended for over the counter sale to lay persons.

SENSITIVITY OF THE TEST
MOP-300ng/ml, MET-1000ng/ml, KET-1000ng/ml, MDMA-500ng/ml, COC-300ng/ml, THC-50ng/ml,
AMP-1000ng/ml,BAR-300ng/ml, BZO-300ng/ml, MTD-300ng/ml, PCP-25ng/ml, BUP-10ng/ml, TCA-1000ng/ml,
OXY-100ng/ml, PPX-300ng/ml, OPI-2000ng/ml.

TEST PROCEDURE
1. Bring the pouched test device to room temperature (15-30℃) prior to testing. Do not open the pouch until ready to perform the assay.
2. Remove the test device from the sealed pouch. Label the device with patient name or control number. Lay it on a flat, clean and dry surface.
3. Hold the dropper vertically and transfer 3 full drops of urine to the sample well (S) of the test device, and then start the timer. Use a separate pipette and device for each specimen or control.
4. Read result between 3 to 8 minutes. Do not read result after 10 minutes.

INTERPRETATION OF RESULTS

Negative: Two red lines are visible in the result window. The line in the test region (T) is the test line and the line in the control region (C) is the control line which is used to indicate proper performance of the device. No matter the color intensity of the test line is weaker or stronger than that of the control line, the test result is negative.

Positive: Only one red line visible in the control region (C) and the absence of the test line indicates a positive result.

NOTICE: A very faint line in the test region indicates that the barbiturates in the specimen is near the cut-off level of the test. These specimens should be retested or confirmed with a more specific method before a positive determination is made.

Invalid: The test is invalid if the control line is not visible regardless of the presence or absence of the test line.

NOTICE: Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for the control line failure. Review the procedure and repeat the test with a new device. If problem persists, please contact your local distributor.
