The BAR Drug Rapid Test is a lateral flow chromatographic immunoassay for the detection of Barbiturates in urine at a cut-off concentration of 300ng/mL of secobarbital. This assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result.

1. Product Details
(1)Product Name: The BAR Drug Rapid Test
2. Direction for Use
Allow the test device, urine specimen and/or controls to reach 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. 100ul) 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.
(1)For healthcare professionals including professionals at point of care sites.
(2)For in vitro diagnostic use only. Do not use after the expiration date.
(3)The test device should remain in the sealed pouch until use.
(4)All specimens should be considered potentially hazardous and handled in the same manner as an infectious agent.
(5) The test device shoud be discarded according to national and local regulations.
The following table lists compounds that are positively detected in urine by the BAR Drug Rapid Test at 5 minutes.

4. Effect of the Urinary pH
The pH of an aliquoted negative urine pool was adjusted to a pH range of 5 to 9 in 1 pH unit increments and spiked with Secobarbital to 150 ng/mL and 450 ng/mL. The spiked, pH-adjusted urine was tested with the BAR One Step Barbiturates Test Device in duplicate. The results demonstrate that varying ranges of pH does not interfere with the performance of the test.
