The ToxSure Oral II measures the following drugs and/or their metabolites at 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.
ToxSure Oral II 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 ToxSure Oral II drug test kit contains of the following inclusions:
Untreated sample collector
The following instructions provide details on how to use ToxSure II to accurately analyse a saliva sample for drugs of abuse.
Remove test device from foil pouch and ensure each testing chamber contains purple dye.
Instruct the donor to rub swab on the inside of their cheek and around gums for 15 seconds on each side of the mouth.
The collector is to insert the swab into buffer solution and rotate 10 times. Remove swab, Place the dropper lid on to buffer bottle.
Dispense 7 drops of the buffer solution into each testing chamber. Close the lid of each chamber softly until lid clicks into place. DO NOT PUSH THE LID FULLY CLOSED.
Shake test devise vigorously for approximately 10 seconds and observe pinkish colour of the solution. Start timer for 4 minutes.
After 4 minutes, close the lid completely by pushing down firmly until lid snaps into place, piercing membrane beneath chambers. Shake test device from side to side for 3 seconds.
Observe pink migration in results window.
Results may be interpreted from 6 minutes if both C lines are present. If one or more of the Test Lines are absent, results may be read in the 11th minute. Do not read results after 12 minutes.
The presence of a line next to both the Control “C” and test 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 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.
