INTENDED USE
The One Step Barbiturates Test is a lateral flow chromatographic immunoassay for the detection of Barbiturates in human urine at the cut-off concentration of 300 ng/ml. This assay provides only a qualitative, preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
SPECIMEN COLLECTION AND PREPARATION
Collect a urine sample in the urine cup. Urine specimens may be refrigerated (2ºC~8°C) and stored up to forty-eight hours. For longer storage, freeze the samples (-20°C or below).
Bring frozen or refrigerated samples to room temperature before testing. Use only clear aliquots for testing.
TEST PROCEDURE
Test must be in room temperature (15ºC to 30ºC)
Device:
1. Remove a testing device from the foil pouch by tearing at the notch and place it on a level surface.
2. Holding a sample dropper vertically, add exactly four drops of the urine specimen to the sample well.
3. Read results in 5 minutes. Do not read after 5 minutes
Strip:
- Remove the test strip from the sealed pouch and use it as soon as possible.
- With arrows pointing toward the urine specimen, immerse the test strip vertically in the urine specimen for at least 10-15 seconds. Do not pass the maximum line (MAX) on the test strip when immersing the strip.
- Place the test strip on a non-absorbent flat surface, start the timer and wait for the red line(s) to appear.
- The result should be read at 5 minutes. Do not interpret the result after 10 minutes.
INTERPRETATION OF RESULTS
Positive (+)
A rose-pink band is visible in the control region. No color band appears in the test region. This positive result indicates that the Barbiturates concentration is equal to or higher than the detection limit(300 ng/ml).
Negative (-)
A rose-pink band is visible in the control region and the test region. This negative result indicates that the Barbiturates concentration is zero or below the detection limit(300 ng/ml).
Invalid
If a color band is not visible in the control region or a color band is only visible in the test region, the test is invalid. Another test should be run to re-evaluate the specimen. If test still fails, please contact the distributor or the store, where you bought the product, with the lot number.
Note: There is no meaning attributed to line color intensity or width.
