Rapid Alcohol Testing Strip

INTENDED USE
Rapid Saliva Alcohol Test Strip is intended for use as a rapid method to detect the presence of alcohol in saliva for blood alcohol concentration (BAC) greater than 0.02%. It has been published that the concentration of alcohol in saliva is almost equal to that in blood.
The rapid test is intended for the semi-quantization of ethyl alcohol in human saliva. To confirm the concentration of positive specimens, an alternate, non-enzymatic technology such as headspace gas chromatography should be used.

PRINCIPLE
Rapid Saliva Alcohol Test Strip is based on the high specify of alcohol oxidase for ethyl alcohol in the presence of peroxides and enzyme substrate such as tetramethylbenzidine (TMB).
The distinct color on reactive pad could be observed in less than 20 seconds after the tip was contacted with saliva samples with the ethyl alcohol concentration greater than 0.02%. It should be pointed out that other alcohols such as methyl, propane and ally alcohol would develop the similar color on the reactive pad. However, these Alcohols are not normally present in saliva.

PROCEDURE

1. Open the foil package and remove the test strip.

2. Saturate the reactive pad by dipping the reaction pad into the saliva specimen collected in a sputum cup, or by applying saliva directly to the reaction pad. After 10 seconds, shake off the excess saliva.

3. Immediately start timer and at 2 minutes, compare the reactive pad with the

provided colored chart. 

Results after more than 2 minutes may be not accurate.

INTERPRETATION OF RESULTS

Negative: Almost no color change by comparing with the background. The 
negative result indicates that the BAC is less than 0.02%.

Positive: A distinct color developed all over the pad. The positive result indicates that the BAC is 0.02% or higher.

Invalid: The test should be considered invalid If only the edge of the reactive pad turned color that might be ascribed to insufficient sampling. The subject should be re-tested.
