Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Performance Data:

  1. Cross-reactivity with structurally similar compounds: Two lots of test Dipcard and one lot of test Cup were used to test with drug metabolites and structurally similar compounds in urine. Compounds were added to drug-free normal human urine. Each sample was tested in 5 replicates using 3 lots of Test Cup and Test Dipcard. If positive, compounds were serially diluted and retested until the highest concentration yielding a negative result was identified. The cross-reacting substances with the lowest concentration that produced a positive result were identified and listed in tables for each drug (Amphetamine, Barbiturates, Buprenorphine, Benzodiazepines, Cocaine, EDDP, MDMA, Methamphetamine, Morphine300, Morphine2000, Methadone, Oxycodone, Phencyclidine, Propoxyphene, Tri-cyclic Antidepressants, Cannabinoids (THC)), showing concentration and cross-reactivity percentage.
  2. Interference: Clinical urine samples potentially containing interfering substances were spiked with drugs (AMP, BAR, BUP, BZO, COC, EDDP, MDMA, MET, MOP, MTD, OXY, PCP, PPX, TCA or THC) at concentrations 50% below and 50% above the cutoff. Potential interfering substances were added at a concentration of 100 μg/mL (confirmed by GC/MS, LC/MS, HPLC). The urine specimens were tested with two lots of the corresponding Rapid Single/Multi-drug Test Cup and Test Dipcard. None of the listed compounds (Acetaminophen, Acetophenetidin, Amoxicillin, etc.) were shown to interfere.
  3. Effect of urinary pH: Negative urine pool pH was adjusted from 3 to 9 in 1 pH unit increments and spiked with each drug at 50% below and 50% above cutoff levels (concentrations confirmed by GC/MS, LC/MS, HPLC). Each sample was tested by two lots of the corresponding Rapid Single/Multi-drug Test Cup and Test Dipcard. Results demonstrated that varying pH ranges do not interfere with performance.
  4. Effect of Urinary specific gravity: Specific gravity studies were conducted on drug-free urine specimens (1.002, 1.010, 1.020, 1.030, 1.040) containing drugs (AMP, BAR, BUP, BZO, COC, EDDP, MDMA, MET, MOP, MTD, OXY, PCP, PPX, TCA or THC) at 50% below and 50% above cutoff level (concentrations confirmed by GC/MS, LC/MS, HPLC). Each sample was tested by two lots of the corresponding Rapid Single/Multi-drug Test Cup and Test Dipcard. Results demonstrated that varying ranges of urinary specific gravity do not affect the test result.
  5. Precision: Precision studies were performed using multi-drug test formats. Drug-free specimens were spiked with analytes at 0, ±75% cutoff, ±50% cutoff, and +100% cutoff (concentrations confirmed by GC/MS, LC/MS, HPLC). Aliquots were blindly labeled, assigned, and randomized. Study conducted by 6 operators at 3 Point-of-Care sites, with 2 operators per location testing 3 aliquots at each concentration for each lot per day (3 runs/day) for 10 non-consecutive days, using one device lot per location. One operator used the test dipcard format, the other the test cup format. There were 1620 observations by 3 sites at 9 concentrations. Results tables are provided for both Multi-drug Test Cup and Multi-drug Test Dipcard, showing positive and negative results for each concentration and lot.
  6. Accuracy:
    • Multi-drug Test Cup: 80 clinical urine specimens for each drug were analyzed by GC/MS or HPLC and by one lot of the Rapid Multi-drug Test Cup. Samples categorized into drug free, less than half cutoff, near cutoff negative, near cutoff positive, and high positive. Results summarized in tables showing Co-Innovation Result (+/-) versus GC/MS analysis categories for each drug. Discordant results were analyzed (e.g., BUP: 10 ng/mL cutoff, negative result at 11.7 ng/mL by LC/MS).
    • Multi-drug Test Dipcard: Same methodology as the Cup, 80 clinical urine specimens per drug analyzed by GC/MS or HPLC and by one lot of the Rapid Multi-drug Test Dipcard, with similar categorization and summary tables for results and discordant results.
  7. Lay User Study: 1720 lay users (18-65 years) participated. Urine samples prepared at 0, +/- 50% cutoff, +/- 25% cutoff, and +100% cutoff by spiking (concentrations confirmed by GC/MS, LC/MS, HPLC). Each sample contained different drugs and concentrations. Participants performed 1 test with one device format (Dipcard or Cup) using the English package insert. They completed an English questionnaire. Results tables for both Multi-drug Test Cup and Multi-drug Test Dipcard show lay user results (positive/negative) for different concentrations and lots, and the agreement percentage. The overall results indicate that the test is easy to use and the instructions are clear.
  8. Interference study (repeated): This section appears to be a re-listing/restatement of the "Interference" study from 8.2, using different phrasing and additional detail on replicates (3 lots, 15 determinations per lot per concentration over 5 non-consecutive days by 6 operators at 3 POC sites, total 180 observations at 4 concentrations for each drug). The results consistently showed 100% positive for samples at +50% and +100% cutoff and 100% negative for samples at 0 and -50% cutoff for all analytes across all lots.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

Key metrics are presented through the performance data tables, displaying raw counts of positive/negative results and agreement percentages at various concentrations (e.g., -25% cutoff, +25% cutoff) for precision and lay user studies. Specific calculated metrics like sensitivity, specificity, PPV, NPV are not explicitly provided in a separate summary section, but can be inferred from the accuracy study data. For example, in the Multi-drug Test Cup accuracy data for AMP:

(a)
Identification. An opiate test system is a device intended to measure any of the addictive narcotic pain-relieving opiate drugs in blood, serum, urine, gastric contents, and saliva. An opiate is any natural or synthetic drug that has morphine-like pharmocological actions. The opiates include drugs such as morphine, morphine glucoronide, heroin, codeine, nalorphine, and meperedine. Measurements obtained by this device are used in the diagnosis and treatment of opiate use or overdose and in monitoring the levels of opiate administration to ensure appropriate therapy.(b)
Classification. Class II (special controls). An opiate test system is not exempt if it is intended for any use other than employment or insurance testing or is intended for Federal drug testing programs. The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9, provided the test system is intended for employment and insurance testing and includes a statement in the labeling that the device is intended solely for use in employment and insurance testing, and does not include devices intended for Federal drug testing programs (e.g., programs run by the Substance Abuse and Mental Health Services Administration (SAMHSA), the Department of Transportation (DOT), and the U.S. military).

Remark:

  • 1、The subject devices have all features of the predicate device except the number of drugs detected. These differences do not affect the performance characteristics of the subject devices.

8. Performance Data:

8.1 Cross-reactivity with structurally similar compounds

To test the cross reactivity of the test, 2 lots of test Dipcard and one lot of test Cup was used to test with drug metabolites and drug structurally similar compounds in urine. All the components were added to drug-free normal human urine. Each sample was tested in 5 replicates using 3 lots of Test Cup and Test Dipcard. If any positive result was observed, the compounds were further diluted with known drug-free urine specimen sequentially to different concentrations and tested in quintuplicate, until the highest concentration that generates a negative result was identified. The cross reacting substances with the lowest concentration that produced a positive result was identified and is listed in the table below.

8.3 Effect of urinary pH

The pH of an aliquot negative urine pool is adjusted to a pH range of 3 to 9 in 1 pH unit increments and spiked with each drug at 50% below and 50% above cutoff levels (All concentrations were confirmed with GC/MS, or LC/MS, HPLC). Each sample was tested by two lots of the corresponding Rapid Single/Multi-drug Test Cup and Test Dipcard. The results

11

demonstrate that varying ranges of pH do not interfere with the performance of the test.

8.4 Effect of Urinary specific gravity

The specific gravity studies were conducted on different specific gravity including 1.002,1.010, 1.020, 1.030, 1.040 specimens with drug free urine containing AMP, BAR, BUP, BZO, COC, EDDP, MDMA, MET, MOP, MTD, OXY, PCP, PPX, TCA or THC at 50% below and 50% above cutoff level (All concentrations were confirmed with GC/MS, or LC/MS, HPLC). Each sample was tested by two lots of the corresponding Rapid Single/Multi-drug Test Cup and Test Dipcard. The results demonstrate that varying ranges of urinary specific gravity do not affect the test result.

8.5 Precision

Precision studies were performed using the multi-drug test formats. Drug free specimens were spiked with analytes at 0, ±75% cutoff, ±50% cutoff and +100% cutoff of The concentrations of the target drugs were confirmed with GC/MS, or LC/MS, drug. HPLC. Each concentration of the urine specimen was then divided into aliquots. Each aliquot was blindly labeled by a nonparticipant. Separate sets of blinded coded samples were assigned and randomized prior to testing. The study was conducted by 6 operators at 3 Point-of-Care sites. Two operators per location tested 3 aliquots at each concentration for each lot per day (3 runs/day) for 10 non-consecutive days using one device lot per location. One operator tested the test dipcard format and the second operator tested the test cup format. There were 1620 observations by 3 sites at 9 concentrations.

8.7 Lay User Study

1720 lay users from age 18 to 65 years participated in the study. Urine samples were prepared at the following concentrations: 0, +/- 50% cutoff,+/- 25% cutoff and +100% cutoff by spiking drug into drug free urine specimens. Each sample contain different drugs and the different concentrations. The concentrations of target drugs were confirmed with GC/MS, or LC/MS, HPLC. Each participant performed only 1 test on provided specimen with one format of Rapid Multi- drug Test (Dipcard, Cup) using the English package insert as guide to perform the test. They were asked to fill out an English questionnaire after finishing the test. Results were as follows:

1720 questionnaires were distributed collected. The results show that the test is easy to be used and the instruction insert is clear.

Evaluation of the readability of the labeling

The entire package insert readability was assessed. We choose 30 chain sentences from Instructions Insert at OTC user read. According to SMOG Conversion Table of Appendix B the SMOG Readability Formula of "Labeling of Home-Use In Vitro Testing Products: Approved Guideline: GP-14A5", the reading level belong to 7th degree.

8.7 Interference study

Interference studies were performed using the multi-drug test formats. Drug free specimens were spiked with single drug at 0, ±50% cutoff and +100% cutoff of drug. The concentrations of the target drugs were confirmed with GC/MS, or LC/MS, HPLC. Each concentration of the urine divided into aliquots. Each aliquot was specimen was blindly labeled by a nonparticipant. Separate sets of blinded coded samples were assigned and randomized prior to The study was conducted by 6 operators at 3 Point-of-Care sites. Operators tested 3 testing. aliquots at each concentration for each lot per day (3runs/day ) and lasted for 5 non-consecutive days. A total of 15 determinations were made by each site at each concentration. There were 180 observations by 3 sites at 4 concentrations.
