L. Test Principle:
The QuickScreen™ Oxycodone Test is a competitive immunoassay that is used to screen for the presence of Oxycodone and its metabolites in urine. It is a chromatographic absorbent device in which drugs or drug metabolites in the sample compete with drug/protein conjugate on a porous membrane for a limited number of antibody/ dye conjugate binding sites. The test device employs a unique combination of monoclonal and polyclonal antibodies to selectively identify Oxycodone and its metabolites.
In the procedure, the absorbent end of the device is inserted in the urine sample. Urine is absorbed into the device by capillary action, mixes with the antibody/ dye conjugate and flows across the pre-coated membrane. When sample Oxycodone levels are below 100 ng/mL (the detection sensitivity of the test) antibody/ dye conjugate binds to the drug / protein conjugate immobilized in the Test Region (T) of the device. This produces a colored Test Band that regardless of its intensity indicates a negative result.
When sample Oxycodone levels are at or above 100 ng/mL, the free drug in the sample binds to the antibody/ dye conjugate, preventing the antibody/ dye conjugate from binding to the drug/ protein conjugate immobilized in the Test Region (T) of the device. This prevents the development of a distinct colored band, indicating a potentially positive sample.
In either case, a colored Control Band is produced in the Control Region (C) by a non-specific antibody-dye/ conjugate reaction. This band serves as a built in quality control device, demonstrating migration of the urine sample across the membrane as well as confirming that the test is complete.
M. Performance Characteristics (if/when applicable):
1. Analytical performance:
a. Precision/Reproducibility:
To determine the precision of the QuickScreen™ Oxycodone Test within and between assays, eight separate normal urine pools were spiked with Oxycodone metabolites as follows:
| | Concentration (ng/mL) |
| --- | --- |
| <1% to 25% of cutoff | 20 |
| 26% to 50% of cutoff | 31 |
| 51% to 75% of cutoff | 62 |
| 76% to cutoff | 77 |
| Cutoff to 125% of cutoff | 105 |
| 126% to 150% of cutoff | 152 |
| 151% to 175% of cutoff | 173 |
| 176% to 200% of cutoff | 199 |
{4}
One replicate of each level was assayed twice a day for twenty days, in accordance with package insert instructions using two lots of the QuickScreen Oxycodone Test. The interpretations of either negative or positive result was recorded in each case and used to evaluate precision. The results of this evaluation are listed in the table below.

To compare the accuracy of the QuickScreen™ Oxycodone Test to detect the presence or absence of Oxycodone in urine samples to results obtained with the American Biomedical RapidOne Oxy Test (ABMC) (k014101) predicate device. A total of one hundred and ninety two (192) samples obtained from clinical sites were used. All sample collection was performed at these clinical sites. Testing was performed at Pharmatech. Immediately upon completion of the assays, results were visually scored as “negative” (absence of Oxycodone metabolites in concentrations of 100 ng/mL or greater) or “positive” (presence of Oxycodone or Oxycodone metabolites in concentrations of 100 ng/mL or greater) by the technician. Quality assurance personnel then verified all results. After all in-house testing was completed the samples were analyzed by gas chromatography / mass spectrometry. Test results were recorded in the equivalency summary protocol by QC personnel.
## Results
Of the 192 urine samples collected 192 were tested. The performance characteristics of the QuickScreen™ Oxycodone Test to the ABMC RapidOne assay are presented in the table below.
