The One-Step Barbiturates Test (Strip) is a lateral flow immunoassay for the qualitative detection of barbiturates (primarily secobarbital) in human urine at a cutoff 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 sales to laypersons.

Test Procedure:

1. Bring the pouched test strip to room temperature (15-30℃) before testing. Do not open the pouch until ready to perform the assay.
2. Remove the test strip from the sealed pouch.
3. Immerse the test strip in the urine specimen with the arrow end pointing toward the urine. Do not immerse the strip above the printed MAX line.
4. After a minimum of 15 seconds, remove the test strip from the urine and lay flat on a non-absorptive clean surface. Alternatively, leave the test strip in the urine specimen as long as the strip is not immersed above the MAX line.
5. Read results between 3-8 minutes. Do not read results after 10 minutes.

• Negative: Two red lines are visible, one in the test region (T) and another one in the control region (C). No matter whether 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 are near the test’s cutoff level. These specimens should be retested or confirmed with a more specific method before a positive determination.)
• 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 the problem persists, contact your local distributor.)
