A lay user study was performed at three intended user sites for BIO-VENTURE Rapid Multi-Drug Test Easy Cup for OTC Use, BIO-VENTURE Rapid Multi-Drug Test Split Key Cup for OTC Use, BIO-VENTURE Rapid Multi-Drug Test Easy Cup for Rx Use, BIO-VENTURE Rapid Multi-Drug Test Split Key Cup for Rx Use separately. The lay users had diverse educational and professional backgrounds and ranged 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. Each sample was aliquoted into individual containers and blind-labeled. Each participant was provided with the package insert, 1 blind labeled sample and a device. Each device was tested.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Analytical Performance - Precision
Precision studies were carried out for samples with concentrations of -100% cut off, -50% cut off, -25% cut off, +25% cut off, +50% cut off and +100% cut off. These samples were prepared by spiking drug in negative samples. Each drug concentration was confirmed by GC/MS. All sample aliquots were blindly labeled by the person who prepared the samples and didn't take part in the sample testing. Each concentration has three lots, and 6 operators have joined the performance. Each operator performs 9 samples for 25 days per device in a randomized order. Results were summarized in tables for AMP Assay, COC Assay, Oxazepam Assay, MET Assay, MOP Assay, and THC Assay for both Split Key Cup and Easy Cup formats, indicating the number of negative and positive results at various percentages of the cut-off.
Analytical Performance - Cut-off
A total of 375 samples equally distributed at concentrations of -50% Cut-Off; -25% Cut-Off; Cut-Off; +25% Cut-Off; +50% Cut-Off were tested using three different lots of each device by three different operators. Results were all positive at and above +25% Cut-off and all negative at and below -25% Cut-off for Amphetamine, Cocaine, Oxazepam, Methamphetamine, Morphine and Marijuana.
Analytical Performance - Stability
The devices are stable at 2-30 ℃ for 24 months based on the real time stability at room temperature.
Analytical Performance - Interference
Potential interfering substances found in human urine of physiological or pathological conditions were added to drug-free urine and target drugs urine with concentrations at 25% below and 25% above Cut-Off levels. These urine samples were tested using three batches of each device. Compounds that showed no interference at a concentration of 100µg/mL and Ethanol at 1% were summarized for AMP Assay, COC Assay, Oxazepam Assay, MET Assay, MOP Assay, and THC Assay.
Analytical Performance - Specificity
To test specificity, drug metabolites and other components that are likely to interfere in urine samples were tested using three batches of each device. The lowest concentration that caused a positive result for each compound was listed. There were no differences observed for different devices. Results were provided for AMP Assay, COC Assay, Oxazepam Assay, MET Assay, MOP Assay, and THC Assay, including concentration and %Cross Reactivity.
Analytical Performance - Effect of Urine Specific Gravity and Urine pH
Urine samples, with 1.002 to 1.036 specific gravity or urine samples with pH 4 to 9 were spiked with target drugs at 25% below and 25% above Cut-off levels. These samples were tested using three lots of each device. Results were all positive for samples at and above +25% Cutoff and all negative for samples at and below -25% Cut-Off. There were no differences observed for different devices.
Comparison Study (Method Comparison Studies with GC/MS)
Method comparison studies were performed in-house with three laboratory assistants for each device. Operators ran unaltered clinical samples: 87 samples for amphetamine, 80 for cocaine, 80 for Oxazepam, 81 for Methamphetamine, 81 for Morphine, and 82 for Marijuana. The samples were blind labeled and compared to GC/MS results. Results were presented in tables showing negative and positive results at various cut-off percentages for Amphetamine, Cocaine, Oxazepam, Methamphetamine, Morphine, and Marijuana Cup and Split Key Cup formats. Discordant results were also listed for each.
Lay-user study
A lay user study was performed at three intended user sites. Lay users had diverse educational and professional backgrounds and ranged in age from 20 to > 50 years. Urine samples were prepared at various concentrations (negative, +/-75%, +/-50%, +/-25% of cutoff) and confirmed by GC/MS. Each participant received a blind-labeled sample and a device. Results were presented in tables for Amphetamine, Cocaine, Oxazepam, Methamphetamine, Morphine, and Marijuana for both Cup and Split Key Cup formats, showing the number of positive/negative results and the percentage of correct results at different cut-off percentages compared to GC/MS. Lay-users indicated that the device instructions were easy to follow. A Flesch-Kincaid reading analysis revealed a reading Grade Level of 7.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

5.7 Test Principle
BIO-VENTURE Rapid Multi-Drug Test Easy Cup for OTC Use, BIO-VENTURE Rapid Multi-Drug Test Split Key Cup for OTC Use, BIO-VENTURE Rapid Multi-Drug Test Easy Cup for Rx Use, BIO-VENTURE Rapid Multi-Drug Test Split Key Cup for Rx Use are rapid tests for the qualitative detection of d-Amphetamine, Oxazepam, d-Methamphetamine, Morphine Benzoylecgonine, 11-Nor-49-Tetrahydrocannabinol-9-COOH in urine samples. The tests are lateral flow chromatographic immunoassays. During testing, a urine specimen migrates upward by capillary action. If target drugs present in the urine specimen are below the cut-off concentration, it will not saturate the binding sites of its specific monoclonal mouse antibody coated on the particles.
The antibody-coated particles will then be captured by immobilized drug-conjugate and a visible colored line will show up in the test line region. The colored line will not form in the test line region if the target drug level exceeds its cutoff-concentration because it
12
will saturate all the binding sites of the antibody coated on the particles. 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 the tests have been performed properly.
5.8 Performance Characteristics
5.8.1 Analytical Performance
a. Precision
Precision studies were carried out for samples with concentrations of -100% cut off, -50% cut off, -25% cut off, +25% cut off, +50% cut off and +100% cut off, These samples were prepared by spiking drug in negative samples. Each drug concentration was confirmed by GC/MS. All sample aliquots were blindly labeled by the person who prepared the samples and didn't take part in the sample testing. Each concentration has three lots, and 6 operators have joined the performance. Each operator performs 9 samples for 25 days per device in a randomized order. The results obtained are summarized in the following tables.
