Device Story
Lateral flow immunochromatographic assay; detects drugs of abuse in human urine. Cassette format houses single drug test strip. Principle: competitive binding; target drugs in urine compete with immobilized drug-conjugate for binding sites on gold-conjugated monoclonal antibodies. Absence of test line indicates positive result (drug concentration exceeds cutoff); presence of test line indicates negative result. Control line confirms proper migration. Used in clinical or home settings; operated by healthcare professionals or lay users. Provides preliminary results; requires confirmatory testing via GC/MS for clinical decision-making. Benefits: rapid, qualitative screening for drug presence.
Clinical Evidence
Bench testing only. Precision/reproducibility evaluated across 3 lots with 6 operators over 25 days. Analytical specificity (cross-reactivity and interference) and matrix effects (pH, specific gravity) demonstrated. Lay user study (n=840) confirmed ease of use and performance across diverse demographics. Method comparison against GC/MS performed for all analytes.
Technological Characteristics
Lateral flow immunochromatographic assay; mouse monoclonal antibodies on gold-conjugated nanoparticles; anti-IgG polyclonal antibody control line. Single-use cassette format. No external energy source. Stable at 2-30°C for 24 months.
Indications for Use
Indicated for qualitative detection of d-Amphetamine, Oxazepam, Benzoylecgonine, d-Methamphetamine, Morphine, and Delta-9-THC-COOH in human urine. Intended for prescription or over-the-counter use as a preliminary screening tool. Requires confirmatory testing (GC/MS).

The BIO-VENTURE test cassettes (noted in the above paragraph) are immunochromatographic assays that use a lateral flow system for the qualitative detection of d-Methamphetamine, Morphine, 11-Nor-Δ⁹-Tetrahydrocannabinol-9-COOH, d-Amphetamine, Cocaine and Oxazepam in human urine. The tests are available in single drug test cassette formats. BIO-VENTURE test cassettes are coated with mouse monoclonal antibodies, each raised against specific drug analytes (deposited on the test line), and a anti-IgG polyclonal antibody (deposited on the control line). The cassettes are provided in individual aluminum foil bags.

The tests are lateral flow chromatographic immunoassays. During testing, a urine specimen migrates across the test strip by capillary action. If target drugs present in the urine specimen are below the cut-off concentration, they will not saturate the binding sites of specific anti-target drug monoclonal mouse antibodies coated on gold-conjugated nanoparticles, allowing the antibody-coated nanoparticles to be captured by immobilized drug-conjugate on the test line, and a visible colored line will show up in the test line region. The colored line in the test line region will not form if the target drug level exceeds its cutoff concentration because it will saturate all the binding sites of the antibody-coated nanoparticles, thus competing for binding to the test line region.
A band should form in the control region of the devices regardless of the presence of drug or metabolite in the sample to indicate that sample has migrated past the test and control line regions.

## Interferences:
Interference was evaluated by spiking the potential interferents below into urine samples at $\pm 25\%$ of the cut-off for the AMP, COC, BNZ, MET, MOP, and THC assays.
All potential interferents were tested at a concentration of $100~\mu \mathrm{g/mL}$ except for THC which was tested at $10~\mu \mathrm{g/mL}$ and $1\%$ Ethanol. There were no deviations from the expected results for any of the three formats.

The effect of pH was evaluated by preparing samples at $\pm 25\%$ of the cutoff for the MET, MOR, THC, AMP, COC, and OXAZ assays and adjusting the pH to 4.00 to 9.00, in increments of $1\mathrm{pH}$ unit. There were no deviations from the expected results.
The effect of specific gravity was evaluated by preparing samples at $\pm 25\%$ of
{13}
the cutoff for the MET, MOR, THC, AMP, COC, and OXAZ assays and adjusting the specific gravity to 1.002, 1.016, 1.018, 1.023, 1.033, and 1.036. There were no deviations from the expected results.

Method comparison testing was conducted using the The BIO-VENTURE Rapid Amphetamine Test Cassette for OTC Use, BIO-VENTURE Rapid Oxazepam Test Cassette for OTC Use, BIO-VENTURE Rapid Cocaine Test Cassette for OTC Use, BIO-VENTURE Rapid Methamphetamine Test Cassette for OTC Use, BIO-VENTURE Rapid Morphine Test Cassette for OTC Use, and BIO-VENTURE Rapid Marijuana Test Cassette for OTC Use devices, but represents expected performance from both the Rx and OTC devices.
Method comparison studies for the BIO-VENTURE Rapid Single Drug Test Cassettes for Amphetamine, Oxazepam, Cocaine and Cocaine metabolites, Marijuana, Methamphetamine, Morphine were performed in-house with three laboratory assistants for each device. Operators ran unaltered clinical samples; 87 samples for amphetamine, 80 samples for cocaine, 80 samples for Oxazepam, 81 samples for Methamphetamine, 81 samples for Morphine and 82 samples for Marijuana. The samples were blind-labeled and compared to results obtained by GC/MS. The results are presented in the tables below:

VENTURE Rapid Marijuana Test Cassette for OTC Use devices with 840 lay persons with diverse educational and professional backgrounds and ranging in age from 20 to <50 years. Urine samples were prepared at the following concentrations; negative, +/-75%, +/-50%, +/-25% of the cutoff by spiking drug(s) into drug free-pooled urine specimens. The concentrations of the samples were confirmed by GC/MS, and the results provided below are from each lay user, who tested only one device at one test concentration. Lay-users were also given surveys on the ease of understanding the package insert instructions (Flesch-Kincaid reading analysis revealed a reading Grade Level of 7 for the device labeling). All lay users indicated that the device instructions could be easily followed.
