'RapidOne' - Amphetamine Test is a one-step, lateral flow immunoassay for the detection of amphetamine in urine. 'RapidOne' - Amphetamine Test is intended for use in the qualitative detection of amphetamine in human urine at 1000 ng/ml. 'RapidOne' - Amphetamine Test is intended for professional use. It is not intended for over the counter sale to non-professionals. The assay is easy to perform, but should not be used without proper supervision. This immunoassay is a simplified qualitative screening method that provides only a preliminary result for use in determining the need for additional or confirmatory testing, i.e., gas-chromatography/mass spectrometry (GC/MS). 'RapidOne' - Amphetamine Test provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a more confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
The assay employed in the 'RapidOne' - Amphevamine Test is based on the same principle of highly specific reaction between antigens and antibodies. This assay is a one-step, immunoassay in which a specially labeled drug (drug conjugate) competes with drug which may be present in the sample for the limited number of binding sites on the antibody. The test device consists of a membrane strip onto which anti-amphetamine monoclonal antibody has been immobilized. A colloidal gold-BSA-amphetamine couplex is dried on a reagent pad. In the absence of any drug in the urine sample, the colloidal gold-complex moves with the urine by capillary action to conta the immobilized drug antibody. An autibody-antigen reaction occurs forming a visible line in the 'test' area. The formation of a visible line in the test area occurs when the test is negative. When drug is present in the urine sample, the drug or metabolite will compete with the immobilized drug conjugate in the test area for the limited antibody sites on the volloidal gold-antibody complex. If sufficient amount of drug is present, it will fill all of the available binding sites, thus preventing attachment of the labeled antibody to the drug conjugate. An absence of a color band (line) in the test area is indicative of a positive result. A control band (line), comprised of a different antibody/antigen reaction, is present on the membrane strip. The control line is not influenced by the presence of drug in the urine, and therefore, should be present in all reactions. A negative urine will produce two colored bands, and a positive sample will produce only one band.
The acceptance criteria and the study proving the device meets them are described below for the 'RapidOne'-Amphetamine Test.

2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: 90 samples were used for the comparative effectiveness study: 50 drug-free, and 40 drug-containing. For the reproducibility study, 40 samples were tested at each of five concentration levels (0, 500, 750, 1000, 1250 ng/ml), with each tested 4 times (twice daily for 5 days), totaling 200 individual tests for reproducibility.
- Data Provenance: Not specified in the provided text (e.g., country of origin, retrospective or prospective).
3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications
Not applicable. The ground truth for the test set was established by established laboratory methods (EMIT II and GC/MS), not by human experts in this context.
4. Adjudication Method for the Test Set
Not applicable. The ground truth was established by laboratory instrumentation (EMIT II and GC/MS), not requiring human adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
Not applicable. This device is a qualitative immunoassay for drug detection. The study compares the device's performance against a predicate device and a gold standard laboratory method (GC/MS), not human readers.
6. Standalone Performance
Yes, a standalone performance study was conducted. The 'RapidOne'-Amphetamine Test was evaluated independently against 90 samples (50 drug-free, 40 drug-containing) and its results were compared to those of the Syva EMIT-II (predicate device) and confirmed by GC/MS. A reproducibility study also assessed the standalone performance across various concentrations.
7. Type of Ground Truth Used
The primary ground truth for the comparative study was Gas Chromatography/Mass Spectrometry (GC/MS), which is considered a confirmatory method for drug testing and provides quantitative results. The predicate device (EMIT II) was also used for initial comparison.
8. Sample Size for the Training Set
The provided summary does not mention a training set sample size or details about a training process. This type of immunoassay device typically does not involve a "training set" in the same way machine learning models do. Its sensitivity and specificity are determined through the properties of the antibodies and reagents, which are developed and validated during the product development process, rather than "trained" on a specific dataset.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as a distinct "training set" and associated ground truth establishment for a machine learning model is not described for this immunoassay device. The device's inherent analytical performance is based on its chemical and biological components.

Intended Use:
'RapidOne' - Amphetamine Test is used for the qualitative detection of d-amphetamine in human urine. This immunoassay is a simplified qualitative screening method that provides only a preliminary result for use in determining the need for additional or confirmatory testing, i.e., gas chromatography/mass spectrometry (GC/MS).
Performance Characteristics:
'RapidOne'-Amphetamine Test will detect 1000 ng/ml of d-amphetamine in urine.
'RapidOne'-Amphetamine Test was compared to EMIT II. Ninety (90) samples were selected for evaluation, fifty (50) of which were found to be drug-free and forty (40) tested as positive by Syva EMIT-II. The forty positive specimens were confirmed and quantified by GC/MS. Both immunoassays correctly identified all of the specimens which contained no drug as negative and determined the 40 drug-containing specimens, ranging in concentration of 750 ng/ml to 58,000 ng/ml, to be positive.
Reproducibility was evaluated using control urines containing concentrations above and below the stated cut-off. Negative urines were also used. Each sample, at each concentration of analyte, was tested 4 times, twice daily, for 5 days,
| Conc. (ng/ml) | # | Result |
