The Fastect® II BUP Drug Screen Dipstick and QuickTox® Drug Screen Dipcard devices are rapid immunochromatographic immunoassays for the qualitative detection of Buprenorphine in human urine at a cut-off concentration of 10 ng/ml. The devices are intended for professional use only. They are not intended for over-the-counter sale to non-professionals.
The Fastect® II BUP Drug Screen Dipstick and QuickTox® Drug Screen Dipcard tests are used to obtain visual, qualitative results. A more specific alternate method must be used in order to obtain a confirmed analytical result. GC/MS or LC/MS are the preferred confirmatory methods.
The Fastect® II BUP Drug Screen Dipstick and QuickTox® Drug Screen Dipcard are based on the principle of highly specific immunochemical reactions between antigens and antibodies. Both devices utilize a competitive immunoassay procedure in which an immobilized drug conjugate competes with the drug present in urine for limited antibody binding sites. If Buprenorphine is present in the urine, it competes with the immobilized drug conjugate for the limited binding sites on the colored antibody colloidal gold conjugate. When a sufficient amount of drug is present, the drug will saturate the antibodies, and the colored colloidal gold conjugate cannot bind to the drug conjugate immobilized on the membrane. Thus, the absence of the purple-red band at the test region indicates a preliminary positive result. However, if there is no drug present to compete for the binding sites of the colored colloidal gold conjugate, it binds to the immobilized drug conjugate to form a visible purple-red band at the test region of the membrane. Thus, the presence of a purple-red band at the test region indicates a negative result. The Fastect II BUP Drug Screen Dipstick and QuickTox® Drug Screen Dipcard devices are standardized to detect Buprenorphine in human urine at a cut-off concentration of 10 ng/ml. These tests can be performed without the use of any additional instruments.
A control band with a different antigen/antibody reaction is added to the immunochromatographic membrane strip and should always appear regardless of the presence of drug or metabolite. The appearance of the control band during testing indicates that the test has completed and the test is valid.
The provided text describes the Fastect® II BUP Drug Screen Dipstick and QuickTox® Drug Screen Dipcard devices, which are immunochromatographic tests for the qualitative detection of Buprenorphine in human urine. The acceptance criteria are based on their accuracy in detecting Buprenorphine at a cut-off concentration of 10 ng/ml compared to GC/MS analysis and a predicate device.
Here's a breakdown of the requested information:
1. A table of acceptance criteria and the reported device performance
The acceptance criteria are implied by the desired agreement with GC/MS and the predicate device. The performance is reported as percent agreement.
Fastect® II BUP Drug Screen Dipstick Test
| Category | Acceptance Criteria (Implied) | Reported Device Performance (% Agreement with GC/MS) |
|---|---|---|
| Positive (+) | High Agreement | 100% |
| Negative (-) | High Agreement | 94% |
QuickTox® Drug Screen Dipcard Test
| Category | Acceptance Criteria (Implied) | Reported Device Performance (% Agreement with GC/MS) |
|---|---|---|
| Positive (+) | High Agreement | 100% |
| Negative (-) | High Agreement | 94% |
Note: The acceptance criteria are not explicitly stated as numerical targets (e.g., "95% agreement"). Instead, the study reports the observed agreement to demonstrate substantial equivalence.
2. Sample size used for the test set and the data provenance
- Sample size: A total of 90 urine specimens were evaluated.
- Data provenance: 50 urine samples were clinical specimens, meaning they were obtained from patients. The remaining samples (40) were likely laboratory-prepared or spiked samples to ensure representation across different concentration ranges. These were previously analyzed by GC/MS.
- Country of origin: Not specified.
- Retrospective or prospective: The description states "clinical specimens previously analyzed by GC/MS," which indicates a retrospective collection and analysis for the clinical samples. The preparation of "near-negative" and "near-positive" samples suggests some prospective manipulation of existing samples or creation of new ones.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- This information is not provided in the text. The ground truth was established by GC/MS analysis, which is an analytical laboratory method, not human expert consensus.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- None in the context of human adjudication. The ground truth was established by GC/MS analysis, an objective laboratory method.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No, an MRMC study was not done. This device is a rapid immunochromatographic test, and its interpretation is typically straightforward (presence or absence of a band). There is no mention of human readers assisting an AI, or vice versa. The comparison was between the device's results, a predicate device, and GC/MS.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Yes, a standalone study was done. The "accuracy" study directly compared the Fastect® II BUP Drug Screen Dipstick and QuickTox® Drug Screen Dipcard devices' results against GC/MS analysis, without human interpretation influencing the device's output. The devices themselves produce a visual result (presence/absence of a band) which is then read. While a human reads the band, the "performance" described refers to the device's ability to produce the correct band pattern.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The ground truth was established using GC/MS (Gas Chromatography/Mass Spectrometry), which is a gold standard analytical method for confirming the presence and concentration of substances like Buprenorphine in urine.
8. The sample size for the training set
- The text does not explicitly mention a training set sample size. This document describes performance validation for a medical device (screening test), not the development and training of a machine learning model. The devices are based on immunochemical reactions, not algorithms that require training data in the typical sense.
9. How the ground truth for the training set was established
- As the device is based on immunochemical principles rather than a machine learning algorithm, the concept of a "training set" and its "ground truth establishment" in the AI/ML context is not applicable. The underlying chemical reactions are inherently designed to detect the target analyte. The performance studies mentioned are for validation and verification, not for training a model.

Safety and Effectiveness Data
Accuracy
A total of 90 urine specimens were evaluated with the Fastect® II BUP Drug Screen Dipstick and QuickTox® Drug Screen Dipcard devices. Of the 90 urine specimens, 50 urine samples were clinical specimens previously analyzed by GC/MS with known Buprenorphine concentrations. Approximately 10% were near-negative samples and at least 10% of the clinical urine samples were near-positive. When near-negative and near-positive clinical urine samples could not be easily obtained, more concentrated clinical urine samples were diluted to make these samples. Both the Fastect® II BUP Drug Screen Dipstick and QuickTox® Drug Screen Dipcard devices were compared with the ACON® BUP One Step Buprenorphine Test Device as well as against the values obtained through GC/MS analysis. The following shows the results obtained from this study:

§ 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).
