OralScan measures the following drugs and/or their metabolites at or below cut-off levels defined by the Australian standard AS 4760:2006, which describes procedures for the collection, detection and quantitation of drugs in oral fluid.
If you would like further information about these narcotics please view our drugs of abuse information page.
OralScan is a combination of individual tests, which undertake analysis for a specific component based on the principle of solid-phase immunoassay technology. Using this method a specific immunochemical reaction between antibodies and antigen is employed to analyse a corresponding compound within a biological matix.
The assay is based on competition between the drug conjugate and any free drug to bind with an antibody. If a drug is present in the specimen undergoing analysis, it competes with drug conjugate for antibody-dye conjugate, which is in limited supply. If the quantity of drug is equal to, or greater than, the cut-off levels of any of the drugs, it inhibits binding of the drug conjugate to the antibody.
This is why, as illustrated below, no test line is visible when a result is positive whereas the presence of a coloured band indicates a negative result.
Each OralScan drug test kit contains of the following inclusions:
Sealed test cassette
Oral collector sponge
Integrated Quality Control (QC)
The following instructions provide details on how to use OralScan to accurately analyse a saliva sample for drugs of abuse.
Ensure that the subject has not had anything in their mouth for 5 minutes prior to testing.
Hold the oral collector by its handle and insert the sponge into the mouth to collect the oral fluid.
Continuously swab the sponge around the mouth.
After sufficient time the collection will become saturated with oral fluid.
Open the top of the Collection Vial and insert the collector, sponge first.
Push the collector down against the strainer to extract the oral fluid.
Close the collection vial and unscrew the cap to expose the dropper.
Gently squeeze the end chamber of the vial and dispense 3 drops into the sample well of the cassette.
Recap the vial
Results should be read after 10 minutes.
The presence of a line next to both the Control “C” and Test “T” indicates a negative result. Please note that this does not necessarily mean there is a complete absence of drug in the specimen, only that the level is below the cut-off given in Australian standard AS 4760:2006.
The absence of a line next to the Test “T” and the appearance of a line next to the Control “C” indicates a positive test result. As with a negative result, this is an indication the concentration of tested drug(s) in the specimen is above the particular cut-off level of that component.
If there is an absence of a line in the Control “C” area following the alloted time the test should be considered invalid. In this case the sample should be re-analysed with a new test, in strict accordance with the documented procedure.
Note: It is important to understand that the colour intensity of Test “T” lines can vary and that the presence of any line, no matter how faint, is still indicitive of what the test suggests.
