Parameters
CupScan measures the following drugs and/or their metabolites at
cut-off levels defined by the Australian standard
AS/NZS 4380:2008, which describes procedures for the collection, detection and quantitation of drugs of abuse in urine.
If you would like further information about these narcotics please view our drugs of abuse information page.
Principle
CupScan is made up of individual test strips, 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 prevents the binding of drug conjugate to the antibody.
As illustrated below, this is why no band is visible on the test line zone when a result is positive, whilst the presence of a coloured band indicates a negative result.
Procedure
Each CupScan drug test kit contains the following inclusions:
-
A built in test cassette
-
Activator key
-
Integrated Quality Control (QC)
-
Results cover
-
Leak-proof lid
-
Integrated temperature strip
-
Tamper evident security seal
-
Product insert
The following instructions provide details on how to use CupScan to accurately analyse a urine sample for drugs of abuse.
-
Remove the CupScan from the sealed foil pouch.
-
Remove the lid and collect the sample, ensuring that the sample is above the minimum fill line.
-
Secure the lid tightly and place the CupScan on a flat surface.
-
Remove the key from the lid and insert it in the side chamber, push to release the sample into the test zone.
-
Place the CupScan on a flat surface.
-
Remove the result window cover to view the results. Results should be viewed at 5-8 minutes.
-
Do not interpret the results after 10 minutes.
Note: If the urine sample has been refrigerated, bring to room temperature (15°C–28°C) prior to activating the test.
Interpretation
Negative
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/NZS 4308:2008.
Positive
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.
Invalid
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.
