Intended Use

The ACON® One Step 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 cut-off concentrations for these drugs are as follows: Amphetamine at 1,000 ng/ml, Cocaine at 300 ng/ml, Methamphetamine at 1,000 ng/ml, Opiates at 2,000 ng/ml, Marijuana at 50 ng/ml and Phencyclidine at 25 ng/ml. They are intended for healthcare professionals including professionals at the point of care sites.

Device Story

Rapid chromatographic immunoassay for qualitative, simultaneous detection of 2-6 drugs in human urine; utilizes competitive binding, lateral flow immunochromatographic principle; mouse monoclonal antibodies detect drugs at specific cut-offs (AMP 1000ng/ml, COC 300ng/ml, mAMP 1000ng/ml, OPI 2000ng/ml, THC 50ng/ml, PCP 25ng/ml). Used at point-of-care sites by healthcare professionals; no instrumentation required. Positive result: absence of colored line in test region; negative result: presence of colored line. Procedural control line confirms proper sample volume and membrane wicking. Provides preliminary analytical results; intended to aid clinical decision-making regarding drug screening.

Clinical Evidence

Clinical evaluation of >1,000 urine specimens compared subject device results against predicate single-drug tests and GC/MS analysis. Results showed high agreement: positive agreement 90-99%, negative agreement 95-99%, and overall agreement 95-99% across all drug analytes. Study included samples with concentrations in the -25% to +25% cut-off range. Physician's office laboratory (POL) study confirmed suitability for point-of-care use.

Technological Characteristics

Lateral flow immunochromatographic assay; competitive binding principle; mouse monoclonal antibodies; visual qualitative readout; no instrumentation; standalone test card/device format.

Indications for Use

Indicated for healthcare professionals at point-of-care sites for the qualitative, simultaneous detection of 2-6 drugs (Amphetamine, Cocaine, Methamphetamine, Opiates, Marijuana, Phencyclidine) in human urine at specified cut-off concentrations.

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).

# Common Name:

Immunochromatographic test for the simultaneously qualitative detection of Amphetamine, Cocaine, Methamphetamine, Opiates, Marijuana, and Phencyclidine 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 Amphetamine, Cocaine, Methamphetamine, Opiates, Marijuana, and Phencyclidine in urine specimens. These tests are used to provide a preliminary analytical result only. Amphetamine, Cocaine, Methamphetamine, Opiates, Marijuana, and Phencyclidine test systems have been classified as Class II devices with moderate complexity.

# Classification Name:

{1}------------------------------------------------

#### Intended Use:

The ACON® One Step 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 cut-off concentrations for these drugs are as follows: Amphetamine at 1,000 ng/ml, Cocaine at 300 ng/ml, Methamphetamine at 1,000 ng/ml, Opiates at 2,000 ng/ml, Marijuana at 50 ng/ml and Phencyclidine at 25 ng/ml. They are intended for healthcare professionals including professionals at the 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 Amphetamine, Cocaine, Methamphetamine, Opiates, Marijuana, and Phencyclidine in urine samples. The test is based on the principle of antigen-antibody immunochemistry. It utilizes mouse monoclonal antibodies to selectively detect elevated levels of Amphetamine, Methamphetamine, Cocaine, Opiates, THC and PCP in urine at the cut-off concentrations of 1,000 ng/ml (AMP), 1,000 ng/ml (mAMP), 300 ng/mL (COC), 2,000 ng/ml (OPI), 50 ng/ml (THC) and 25 ng/ml (PCP). 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 Amphetamine, Cocaine, Methamphetamine, Opiates, Marijuana, and Phencyclidine at the concentrations below the designated cut-off 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™ of Amphetamine, Cocaine, Methamphetamine, Opiates, Marijuana, and Phencyclidine 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.
