Standard/Guidance Document Referenced (if applicable): None referenced ### L. Test Principle: The candidate devices are rapid lateral flow immunoassays in which drug-protein conjugates in the test device compete with drugs or drug metabolites that may be present in urine. On each test strip, a drug-protein conjugate is added to the test band of the membrane known as the test region (T), and the anti-drug antibody-colloidal gold conjugate pads are placed at the forward end of the membrane. If target drugs are present in the urine specimen 8 {8} below its cut-off concentration, the solution of the colored antibody-colloidal gold conjugates moves along with the sample solution by capillary action across the membrane to the immobilized drug-protein conjugate zone on the test band region. The colored antibody-gold conjugates then complexes with the drug-protein conjugates to form visible lines. Therefore, the formation of the visible precipitant in the test band indicates a negative result. Unbound target drug in urine competes with drug protein conjugates on the test band region for the limited antibody on the colored drug antibody-colloidal gold conjugate pad. If target drug is present in excess of the cutoff, the drug will saturate the limited antibody binding sites and the colored antibody-colloidal gold conjugate cannot bind to the drug-protein conjugate at the test region of the test strip. Therefore, absence of the color band on the test region indicates a preliminary positive result. A band should form in the control region (C) of the devices regardless of the presence of drug in the sample to indicate that the test has been performed properly. ### M. Performance Characteristics (if/when applicable): #### 1. Analytical performance: ##### a. Precision/Reproducibility: A precision/reproducibility study was performed using 3 lots per device format (cup and panel) five replicates per day for five consecutive days by 3 Point of care (POC) personnel, at 3 POC sites. Blinded, drug-free urine and commercial GC/MS confirmed spiked urine samples at the following concentrations were used: -100%, -75%, -50%, -25%, cutoff, +25%, +50% and +100% of the cutoff level. Precision performance of the different trade name devices within a format (i.e. within the cup format or within the panel and dipstick formats) is the same (since these different trade name devices differ only by intended user, the presence absence of adulteration strips, or the presence of the plastic housing (in the case of the panel vs. dipstick formats)). Therefore, in the precision studies conducted by the sponsor, the Single and Multi-Drug Rapid Test Panel (Urine) results were found to support performance of the all test panel devices and dipstick devices, and the Single and Multi-Drug Rapid Test Cup (Urine) results are intended to support performance of the all cup devices.

Linearity/assay reportable range: Not applicable. c. Traceability, Stability, Expected values (controls, calibrators, or methods): The devices have internal process controls. A control line appears in the control region confirming that sufficient sample volume has been applied to the test strip and that the sample has migrated correctly on the test strip. Users are informed that the test is invalid if the colored line does not appear in the control region. There are no external controls supplied with the devices. Accelerated testing demonstrated 36 months shelf-life at room temperature. Real time stability is on-going. Protocol and acceptance criteria were found to be 15 {15} acceptable. # d. Detection limit: See precision data in Section M.1.a., above, for assay performance around the claimed cutoff concentrations. # e. Analytical specificity: The analytical specificity performance of the different trade name devices within a format (i.e. within the cup format or within the panel and dipstick formats) is the same (since these different trade name devices differ only by intended user, the presence absence of adulteration strips, or the presence of the plastic housing (in the case of the panel vs. dipstick formats)). Therefore, in the cross-reactivity, interference and endogenous interferent studies conducted by the sponsor, the Single and Multi-Drug Rapid Test Panel (Urine) results were found to support performance of the all test panel devices and dipstick devices, and the Single and Multi-Drug Rapid Test Cup (Urine) results are intended to support performance of the all cup devices. # Cross-reactivity: Cross-reactivity was evaluated by spiking various concentration of similarly structured drug compounds into drug-free urine, using 3 lots of each device format (cup and panel). Results are expressed as the lowest concentration producing a positive result (ng/ml). The cup and panel configurations demonstrate comparable performance. The results of one test configuration (Multi-Drug Rapid Test Cup) are presented in the table below.

potential interferents below into urine samples having test drug analytes at 25% below and 25% above the cutoff levels for each assay, using 3 lots of each device format (cup and panel). All potential interferents were tested at a concentration of 100 µg/mL, except for ethanol which was tested at a final concentration of 1%. 21 {21} There were no interferences identified for any of the potential interferents provided in the tables below for each device, for either cup or panel configurations.

+/-25% of the cutoff for all devices and adjusting the pH to 2.00 to 9.00, in increments of 1 pH unit. There were no interferences observed. The effect of specific gravity was evaluated by preparing samples with test drug analytes at +/-25% of the cutoff for all devices and adjusting the specific gravity to 1.001, 1.010, 1.015, 1.020, 1.025, and 1.030. There were no interferences observed. #### f. Assay cut-off: Characterization of how the device performs analytically around the claimed cutoff concentration appears in the precision section M.1.a., above. ### 2. Comparison studies: #### a. Method comparison with predicate device: Method comparison studies were performed at the manufacturer's site using three operators for each device format (cup and panel). Operators tested a minimum of 40 unaltered positive and 40 unaltered negative clinical samples for each drug. The samples were blind labeled and compared to GC/MS results. Accuracy performance of the different trade name devices within a format (i.e. within the cup format or within the panel and dipstick formats) is the same (since these different trade name devices differ only by intended user, the presence absence of adulteration strips, or the presence of the plastic housing (in the case of the panel vs. dipstick formats)). Therefore, in the method comparison study conducted by the 32 {32} sponsor, the Single and Multi-Drug Rapid Test Panel (Urine) results were found to support performance of the all test panel devices and dipstick devices, and the Single and Multi-Drug Rapid Test Cup (Urine) results are intended to support performance of the all cup devices. The results are presented in the tables below.
