They are intended for healthcare professionals including professionals at point of care sites.

Device Story

Rapid chromatographic immunoassay; lateral flow; competitive binding principle. Detects Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates, and Tricyclic Antidepressants in human urine. Input: urine sample; output: visual colored lines on test card/device. No instrumentation required. Used by healthcare professionals at point-of-care sites. Positive result: absence of colored line in test region; negative result: presence of colored line. Procedural control line confirms proper wicking. Provides preliminary analytical screening; results used to guide clinical decision-making, typically requiring confirmation by GC/MS.

Clinical Evidence

Clinical evaluation compared subject device against GC/MS and predicate single-drug tests using >1,000 urine specimens. Results showed high agreement: positive agreement 93->99%, negative agreement 94->99%, overall agreement 95-99% across all analytes. Study included 10% of samples in the ±25% cutoff range. Data confirms performance is equivalent to predicate devices.

Technological Characteristics

Lateral flow immunochromatographic assay; competitive binding format. Utilizes mouse antibodies for specific drug detection. Form factor: test card or test device. No external energy source or connectivity. Visual readout. Qualitative result.

Indications for Use

Regulatory Classification

Identification

A barbiturate test system is a device intended to measure barbiturates, a class of hypnotic and sedative drugs, in serum, urine, and gastric contents. Measurements obtained by this device are used in the diagnosis and treatment of barbiturate use or overdose and in monitoring levels of barbiturate to ensure appropriate therapy.

Special Controls

*Classification.* Class II (special controls). A barbiturate 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).

ACON One Step Multi-Drug Multi-Line Screen Test Device

## Common Name:

Immunochromatographic test for the simultaneously qualitative detection of Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants in urine.

## Device Classification:

The ACON One Step Multi-Drug Multi-Line Screen Test Card and Test Device are similar to other FDA-cleared devices for the qualitative and simultaneous detection of Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants in urine specimens. These tests are used to provide a preliminary analytical result only. Benzodiazepines, Tricyclic Antidepressants, Barbiturates, MDMA, Methadone and Opiates test systems have been classified as Class II devices with moderate complexity.

## Classification Name:

Barbiturate, Benzodiazepine, Methadone, MDMA, Opiate and Tricyclic Antidepressant test system

# Intended Use:

The ACON® One Step Multi-Drug Multi-Line Screen Test Card and Test Device are rapid chromatographic immunoassays for the qualitative and simultaneous detection of two to six drugs in a variety of combinations in human urine samples. The designated cutoff concentrations for these drugs are as follows: Barbiturates at 300 ng/mL, Benzodiazepines at 300 ng/mL, Methadone at 300 ng/mL, Methylenedioxymethamphetamine (Ecstasy) at 500 ng/mL, Opiates at 300 ng/mL and Tricyclic antidepressant at 1,000 ng/mL. They are intended for healthcare professionals including professionals at point of care sites.

# Description:

The ACON One Step Multi-Drug Multi-Line Screen Test Card and Test Device are competitive binding, lateral flow immunochromatographic assays for the qualitative and simultaneous detection of Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants in urine samples. The test is based on the principle of antigenantibody immunochemistry. It utilizes mouse antibodies to selectively detect elevated levels of Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants in urine at Cutoff concentrations of 300 ng/mL (BZO), 1,000 ng/mL (TCA), 300 ng/mL (BAR), 500 ng/mL (MDMA), 300 ng/mL (MTD) and 300 ng/mL (MOP). These tests can be performed without the use of an instrument.

A positive urine specimen will not generate a colored-line for the specific drug tested in the designated test region. A negative urine specimen or a urine specimen containing of Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants at the concentrations below the designated cutoff levels will generate a colored-line in the designated test region for the drug. To serve as a procedural control, a colored-line will always appear at the control region, indicating that proper volume of specimen has been added and membrane wicking has occurred.

## Predicate Devices:

ACON™ Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants Single Drug Test strips were used as the predicate devices for the ACON® One Step Multi-Drug Multi-Line Screen Test Card and Test Device to compare their performance with clinical urine specimens.

- Both tests are intended as a screening method that provides a preliminary analytical test ● result.
- . Both tests are immunochromatographic, lateral flow assays for the rapid detection of Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants with a visual, qualitative end result, while ACON Multi-Drug Multi-Line Test detects 2 to 6 of the above drugs simultaneously.
- Both tests utilize the same basic immunoassav principles that rely on antigen/ antibody interactions to indicate a positive or negative result.
- Both tests have the same Cutoff for each drug test.

## Safety and Effectiveness Data:

## Accuracy

A clinical evaluation was conducted using clinical urine specimens. This evaluation compared the test results between the ACON One Step Multi-Line Screen Test Card and the Test Device versus previously FDA-cleared Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants Single tests; as well as against data obtained from the customary GC/MS analysis. Over 1,000 clinical specimens were employed including approximately 10% of the samples with drug concentrations in the -25% to +25% Cutoff range. The comparisons of data obtained from this study yielded the following results:

{3}------------------------------------------------

Clinical study results of ACON One Step Multi-Drug Multi-Line Screen Test Card and Test Device are compared to GC/MS analysis data:

The GC/MS Cutoff levels for each of the six drugs tested are as follows:

| Barbiturates (BAR) at | 300 ng/mL |
|------------------------------------|-------------|
| Benzodiazepines (BZO) at | 300 ng/mL |
| Methadone (MTD) at | 300 ng/mL |
| MDMA (Ecstasy) at | 500 ng/mL |
| Opiates (MOP) at | 300 ng/mL |
| Tricyclic Antidepressants (TCA) at | 1,000 ng/mL |

Samples with drug concentration above the Cutoff level were considered presumptive positive and concentrations below the Cutoff are considered negative.

#### Conclusion:

Clinical study results demonstrate the substantial equivalency between the ACON One Step Multi-Drug Multi-Line Screen Test Card and Test Device and the Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants single tests, which have already been cleared by FDA and marketed in the United States. It is also demonstrated that these tests are safe and effective in detecting Barbiturates, Benzodiazepines, Methadone, MDMA, Opiates and Tricyclic Antidepressants at the following Cutoff concentrations: Barbiturates 300 ng/mL, Benzodiazepines 300 ng/mL, Methadone 300 ng/mL, MDMA 500 ng/mL, Opiates 300 ng/mL and Tricyclic Antidepressants 1,000 ng/mL. The physician's office laboratory POL study demonstrated that these tests are also suitable for use by professionals at point-of-care sites.
