CR3 Keyless Split Sample Cup Morphine-Oxazepam is a rapid test for the qualitative detection of Morphine (a drug in the opiate class) and Oxazepam(a drug in the benzodiazepine class) in human urine at a cutoff concentration of 2000ng/mL and 300ng/mL, respectively.

The tests may yield preliminary positive results even when prescription drugs including Morphine and Oxazepam are ingested, at prescribed doses; it is not intended to distinguish between prescription use or abuse of these drugs. There are no uniformly recognized cutoff concentration levels for morphine and oxazepam in urine. The test provides only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. GC/MS is the preferred confirmatory method. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive.

For in vitro diagnostic use only. It is intended for over-the-counter and for prescription use.

Device Description

Immunochromatograph assays for Opiate and Benzodiazepines Urine Tests use a lateral flow, one step system for the qualitative detection of Morphine and Oxazepam in human urine. Each assay uses a monoclonal antibody-dye conjugate against drugs with gold chloride and fixed drug-protein conjugates and anti-mouse IgG polyclonal antibody in membranes.

Study Details:

Test Set Sample Size and Data Provenance:
- Precision Study: For each concentration level (-100%cut off, -75%cut off, -50%cut off, -25%cut off, +25%cut off, +50%cut off , +75%cut off and +100%cut off), tests were performed two runs per day for 25 days with three different lots of devices. This means 50 tests per concentration per lot for a total of 450 tests per lot for 9 concentrations. With 3 lots, this amounts to 1350 tests for Morphine and 1350 tests for Oxazepam in the precision study.
- Comparison Studies (Professional Users): 80 unaltered clinical samples in total (40 negative and 40 positive) were used for each drug (Morphine and Oxazepam). The provenance is "in-house," implying these were likely collected for the purpose of the study. The text does not specify the country of origin, but the company is based in Guangzhou, P.R. China. The samples were "clinical samples," and the study compared device results to GC/MS, making it a prospective assessment within the study's scope, though the collection method of the initial clinical samples isn't fully detailed.
- Lay-User Study: 260 lay persons participated. For each drug, urine samples were prepared at 7 different concentrations, with 20 samples per concentration. This means 140 samples were tested for Morphine and 140 samples were tested for Oxazepam within this study using lay users. The samples were "prepared" by spiking drug-free pooled urine, indicating controlled, laboratory-prepared samples. Data provenance is implied as "in-house."
Number of Experts and Qualifications:
- Comparison Studies (Professional Users): "three laboratory assistants with relevant experience" were used. Specific qualifications (e.g., number of years of experience, specific certifications) are not provided beyond "relevant experience."
- Lay-User Study: One "lay person" was also included in the comparison study for context, but not to establish ground truth.
Adjudication Method:
- For the precision study and lay-user study, the comparison for correctness was directly against the known prepared concentrations.
- For the comparison studies with professional users, the device results were compared directly against independently confirmed GC/MS results, meaning GC/MS served as the definitive ground truth, and no explicit expert adjudication method (like 2+1 or 3+1) was used between the viewers. The viewers independently interpreted the device results, and these were then compared to the GC/MS.
Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
- No MRMC comparative effectiveness study was explicitly performed to measure the effect size of how much human readers improve with AI vs. without AI assistance. This device is a rapid test kit, not an AI-assisted diagnostic tool.
Standalone (Algorithm Only) Performance:
- This is not applicable as the device is a lateral flow immunoassay, a chemical test, and does not involve an algorithm or AI. The results are visually interpreted.
Type of Ground Truth Used:
- Precision and Lay-User Studies: Ground truth was established by known concentrations of the drugs (spiked samples), confirmed by GC/MS.
- Comparison Studies (Professional Users): Ground truth was established by GC/MS (Gas Chromatography/Mass Spectrometry) results for unaltered clinical samples. GC/MS is considered the "preferred confirmatory method" and is an objective chemical analysis.
Training Set Sample Size:
- The document does not explicitly mention a "training set" in the context of machine learning or algorithm development, as this is a chemical diagnostic device. The performance characteristics describe validation studies, not training data for an algorithm.
How Ground Truth for Training Set was Established:
- Not applicable, as there is no "training set" for an algorithm. The development of the immunochromatographic assay itself would involve laboratory testing and optimization, but this wouldn't be referred to as establishing ground truth for a training set in the AI sense.

9. Test Principle

It is a rapid test for the qualitative detection of Morphine and Oxazepam in urine samples. It is a lateral flow chromatographic immunoassay. When the absorbent end is immersed into a urine sample, the urine is absorbed into the device by capillary action and mixes with the antibody-dye conjugate, flowing across the pre-coated membrane. At analyte concentration below the target cut off, antibody-dye conjugates bind to the drug-protein conjugate immobilized in the Test Region (T) of the device. This produces a colored test line that indicates a negative result. When analyte concentration is above the cutoff, analyte molecules bind to the antibody-dye conjugate, preventing the antibody-dye conjugate from binding to the drug-protein conjugate immobilized in the Test Region (T) of the device. No colored band shows in the test region, indicating a preliminary positive result.

Density (Specific Gravity)

{6}------------------------------------------------

12 urine samples with density ranges (1.000-1.035) are collected and spiked with each drug at 25% below and 25% above cutoff levels. Each sample was tested by three batches of CR3 Keyless Split Sample Cup Morphine-Oxazepam. It shows that urine density does not affect test results.

Lay-user study

A lay user study was performed at three intended user sites with 260 lay persons. Participants in the study were 79 males and 47 females tested the Morphine samples, 74 males and 60 females tested the Oxazepam samples. They had diverse educational and professional backgrounds and ranged in age from 21 to >50. Urine samples' were prepared at the following concentrations; -100%, +/-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, I blind labeled samples and a device. The results are summarized below.

Regulation Number and Section

§ 862.3650 Opiate test system.

(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).
