Oral fluid screening devices provides a fast indication whether a saliva sample contains a drug. Once saliva has been collected by an oral collector, analysis commence. After 5-10 minutes the result can be read in terms of an appearance of a line or no-line on a strip that represents a specific drug.
A line signifies a negative sample and absence of a line a presumptive positive sample. We don’t say positive sample as the result should be verified by a confirmatory test at a toxicology laboratory first.
Considering that more than 95% (typically) of the tests are negative – the main purpose of a screening device is to sort out the negatives from the non-negatives i.e. let the negative tests pass without further testing and concentrate on the presumptive positives with a confirmatory lab testing.
Oral fluid screening devices are regulated by an Australian standard – AS4760:2019 defining cut off levels for six different drugs. Our current supplier ABBOTT Alere is undertaking development and tests in order to meet the standard.
