L. Test Principle:
The Randox Laboratory Ltd. Opiates Assay is an immunoassay with ready to use liquid reagent. The assay is based on competition between drug in the sample and drug labeled with the enzyme glucose-6-phosphate dehydrogenase (G6PDH) for a fixed amount of antibody in the reagent. In the absence of drug in the sample, morphine-labeled G6PDH conjugate is bound to antibody, and the enzyme activity is inhibited. When free drug is present in the sample, the antibody will bind to the free drug and the unbound morphine-labeled G6PDH then exhibits its maximal enzyme activity. Active enzyme converts nicotinamide adenine dinucleotide (NAD) to NADH, resulting in an absorbance change that can be measured spectrophotometrically at 340 nm.
M. Performance Characteristics (if/when applicable):
1. Analytical performance:
a. Precision/Reproducibility:
Precision was determined by spiking Morphine (1 mg/ml solution) into drug free urine at various concentrations (-100%, -75%, -50%, -25%, cut off, +25%, +50%, +75% and +100%). Concentrations were confirmed by GCMS. Intra-assay precision was performed over 20 nonconsecutive days. The between run testing was performed in replicate twice a day for 20 days. The qualitative and semi-quantitative results are presented below:

b. Linearity/assay reportable range:
Recovery across the range was determined by testing a series of samples that were diluted from the high concentration Morphine spiked urine sample. A high urine sample containing around 4000 ng/mL Morphine was serially diluted with analyte-free urine and tested in triplicates in the semi-quantitative mode. The results were averaged and compared to the expected result and the percent recovery was calculated. Results are presented in the tables below.

c. Traceability, Stability, Expected values (controls, calibrators, or methods):
Traceability and value assignment
The 5 level multi-drug calibrator (0 ng/mL, 300 ng/mL, 1000 ng/mL, 2000 ng/mL, 4000 ng/mL) and 2 level multi-drug control materials (1500 ng/mL, 2500 ng/mL) are both traceable to master lots that have been GC/MS quantified. The master lots were made by spiking morphine, methadone, methamphetamine and secobarbital at the appropriate levels into a buffered human urine matrix that also contains 0.05% sodium azide. The drugs used to make the calibrators and controls are supplied by Cerilliant Corporation the accuracy of which is ensured by purity determinations (GC/FID, HPLC and NMR) and gravimetric preparation using balances calibrated with NIST traceable weights. Each of the Randox calibrator/control level is value assigned using Rx Daytona and Rx Imola. The
{7}
target value for each level is the median of the observed values.
## Stability
Real time stability testing including shelf-life and on-board stability studies were performed for the assay, controls and calibrators. The acceptance criteria were found to be adequate. The Randox Opiates assay reagents, controls and calibrators are stable for 18 moths when stored unopened at $2 - 8^{\circ}\mathrm{C}$ and 28 days on-board at approximately $10^{\circ}\mathrm{C}$.
## d. Detection limit:
Performance at low drug concentrations in the semi-quantitative assay was characterized by determination of recovery (see section b above).
## e. Analytical specificity:
The Randox Laboratory Ltd. Opiate Assay was evaluated for interference according to the CLSI Guideline EP7-A2 recommendations. These studies were performed by spiking structurally related and unrelated compounds into drug-free and drug-containing urine samples. Drug-containing urine samples were tested at two different concentrations, $+25\%$ and $-25\%$ of the cut-off concentration of 2000 ng/mL. Drug-free urine samples were used as controls. Percent cross-reactivity was calculated using the cross-reactant concentration that gives a reaction absorbance which matches the reaction absorbance obtained by the cut-off calibrator. The cut-off calibrator concentration divided by the cross-reactant concentration that achieved the matching reactant absorbance $\times 100\%$ gives the percent cross reactivity. These studies were performed on both, the Rx Daytona and Rx Imola analyzers. Similar results were obtained with both analyzers and in both qualitative and semi-quantitative modes. The percent cross-reactivity of the tested compounds are presented below:
