Indications for Use

The One Step Drugs of Abuse Test is a prescription lateral flow competitive immunoassay panel or single test intended for professional central laboratory use by trained users. It provides qualitative visual screening results for Marijuana, Cocaine, Morphine, Amphetamine and Methamphetamine at cutoff concentrations of 50 ng/mL Marijuana, 300 ng/mL Morphine, 1000 ng/mL Morphine, 1000 ng/mL Amphetamine and 1000 ng/mL Methamphetamine in urine in combinations (Multi-Panel) or separately (Single). It is not intended for over the counter sales to the lay person. For in vitro diagnostic use only. As with all qualitative tests, this assay provides only a preliminary result. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly in evaluating a preliminary positive result. To obtain a confirmed analytical result, a more specific alternate chemical method is needed. Gas chromatography/mass spectroscopy (GC/MS) is the recommended confirmatory method

Device Story

Lateral flow competitive immunoassay; detects drugs of abuse in urine. Input: urine sample (dip strip or cassette well). Principle: drug conjugate competes with drug in urine for limited antibody binding sites; antibody-colloid gold conjugate moves via capillary action. Output: visual pink line on test band (negative) or absence of line (positive). Used in professional central laboratories by trained personnel. Provides preliminary screening results; requires confirmatory testing (GC/MS) for clinical decision-making. Benefits: rapid, qualitative identification of drug presence to guide further diagnostic or clinical action.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Lateral flow competitive immunoassay; visual readout; urine matrix; cutoff concentrations: 50 ng/mL (Marijuana), 300/1000 ng/mL (Morphine), 1000 ng/mL (Amphetamine/Methamphetamine).

Indications for Use

Indicated for professional laboratory use for qualitative screening of Marijuana, Cocaine, Morphine, Amphetamine, and Methamphetamine in human urine. Not for OTC or point-of-care use.

Regulatory Classification

Identification

An amphetamine test system is a device intended to measure amphetamine, a central nervous system stimulating drug, in plasma and urine. Measurements obtained by this device are used in the diagnosis and treatment of amphetamine use or overdose and in monitoring levels of amphetamine to ensure appropriate therapy.

Special Controls

*Classification.* Class II (special controls). An amphetamine 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).

H. Intended Use:

1. Intended use(s):

See indications for use.

2. Indication(s) for use:

The One Step Drugs of Abuse Test is a prescription lateral flow competitive immunoassay panel or single test intended for professional central laboratory use by trained users. It provides qualitative visual screening results for Marijuana, Cocaine, Morphine, Amphetamine and Methamphetamine at cutoff concentrations of 50 ng/mL Marijuana, 300 ng/mL Cocaine, 300 ng/mL Morphine, 1000 ng/mL Amphetamine and 1000 ng/mL Methamphetamine in urine in combinations (Multi-Panel) or separately (Single). It is not intended for over the counter sales to the lay person.

For in vitro diagnostic use only.

As with all qualitative tests, this assay provides only a preliminary result. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used. To obtain a confirmed analytical result, a more specific alternative chemical method is needed. Gas chromatography/Mass spectrometry is the recommended confirmatory method.

3. Special conditions for use statement(s):

The assay is for prescription use. The assay is not designated for use in point-of-care settings.

4. Special instrument requirements:

Not applicable. The device is a visually read single-use device.

I. Device Description:

The product may be sold as a single test or as part of a panel, and may be packaged in either a strip or a cassette format. Operators dip the test strip into the urine, or add drops of urine to the cassette test well to initiate the test reaction. Results are visually read.

The sponsor indicates the device has no human source material.

1. Predicate device name(s):

Princeton Biomeditech Accusign DOA 5

2. Predicate 510(k) number(s):

k962353

3. Comparison with predicate:

Both devices have the same intended use, utilize the same test methodology and have the same cutoff concentrations. The reagent formulations vary between the two devices, as do the manufacturers.

## K. Standard/Guidance Document Referenced (if applicable):

The sponsor did not reference any standards in this submission.

## L. Test Principle:

The test is based on the principle of a competitive inhibition immunoassay, in which a chemically labeled drug (drug conjugate) competes with the drug which may be present in urine, for limited antibody binding sites. The test device consists of a membrane strip, which is pre-coated with DOA-BSA conjugate on the test band region, and a colored anti-DOA monoclonal antibody-colloid gold conjugate pad, which is placed at the end of the membrane.

In the absence of drug in the urine, the colored antibody-colloid gold conjugate moves with the sample by capillary action along the membrane until it reaches the immobilized drug conjugate in the test band region. At this point, the antibody-colloid gold conjugate reacts with the pre-coated drug conjugate and forms a visible pink colored line as the antibodies form complexes with the drug conjugate. Therefore, formation of a visible pink color line on the test band region is interpreted as a negative test result.

When the drug is present in the urine, the drug/metabolite antigen will compete with the drug conjugate coated in the test band region for the limited antibody sites. When a sufficient concentration of drug is present, it will fill the limited antibody binding sites, and will prevent attachment of the colored antibody-colloid gold conjugate to drug conjugates pre-coated in the test band region. Therefore, absence of the pink color band on the test region indicates a positive result for the specified drug. A control line indicates that an adequate volume of sample was added and that the test membrane is intact.

a. Precision/Reproducibility:

Precision of the test was characterized at the sponsor's facility by two trained technicians. Replicates of drug-free urine were tested, as well as drug-free urine spiked to the cutoff concentration, 25% above the cutoff concentration, and 25% below the cutoff concentration. Testing was performed on strip, cassette, and multi-panel test formats. Results are presented below.

b. Linearity/assay reportable range:

Not applicable. The assay is intended for qualitative use.

c. Traceability, Stability, Expected values (controls, calibrators, or methods):

Controls are required with this assay but are not specifically identified in the labeling. The sponsor did not indicate any degree of traceability for their devices. Users are instructed to follow federal, state, and local guidelines concerning QC practices.

d. Detection limit:

Sensitivity of a qualitative assay may be characterized by validating performance around the claimed cutoff concentration of the assay, and demonstrating the lowest concentration of drug that is capable of or consistently producing a positive result. This information appears in the precision section, above.

e. Analytical specificity:

An extensive list of compounds were tested for positive interference. Each compound was dissolved in drug-free control urine to a concentration of 100 µg / mL. Samples were adjusted to 3 pH levels (5, 7, 9) and 3 specific gravity levels (low, normal, high). All test results were negative.

Cross-reactivity of structurally related compounds was estimated by testing various amounts of drug or drug metabolite added to a drug-free urine control. Results are expressed as the lowest concentration required to produce a positive result.
