You’ve collected the specimen amount required and you are about to see the results. The good news is that you have already done the hard part, collecting the sample. Now it’s all down to actually dabbing the strip into the specimen, be it saliva or another liquid you want to test, and matching the color on the reactive pad. When it comes to administering this test, it’s really not difficult at all. It’s important to know how to read the Alco-Screen test results.
The results should show up in about 2 minutes (or less) if everything has gone well. By that, I mean if no tampering of any kind has been done. Just so you know, any results obtained after more than 2 minutes and 30 seconds may be erroneous and you may want to try a new test strip.
When interpreting, you should choose the closest color match to estimate the alcohol concentration within the first 15 seconds. A color change of green or blue indicates the presence of alcohol and a positive result. No color change on reactive pad would mean a negative.
