Intend Use 

One Step DOA (Single Item) Urine Test Panels/Strips/Cassettes are intended for the qualitative detection of DOA markers and their principal metabolites in human urine at specified cut-off level. 

The One Step Ethyl Glucuronide Test is a lateral flow chromatographic immunoassay for the detection of Ethyl Glucuronide at the cut-off level of 500 ng/ml.

The assay is intended to verify an intoxication in patients. It provides 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 results are positive.

Device:

• Remove a testing device from the foil pouch by tearing at the notch and place it on a level surface.

• Holding a sample dropper vertically, add exactly four drops of the urine specimen to the sample well.

• Read results at 5 minutes. Do not read after 10 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.
