Intended Use
The ACON AMP One Step Amphetamine Test Strip and ACON AMP One Step Amphetamine Test Device are rapid chromatographic immunoassays for the qualitative detection of amphetamine in human urine at a cut-off concentration of 1,000 ng/mL. These tests are for professional and point of care use.
Device Description
The ACON AMP One Step Amphetamine Test Strip and ACON AMP One Step Amphetamine Test Device are competitive binding, lateral flow immunochromatographic assays for the qualitative screening of amphetamine, in a urine sample. The test is based on the principle of antigen-antibody immunochemistry. It utilizes a monoclonal antibody to selectively detect elevated levels of amphetamine in urine at a cut-off concentration of 1,000 ng/mL. These tests can be performed without the use of an instrument. A drug-positive urine specimen will not generate a colored line in the test line region. while a drug negative urine specimen will generate a line in the test line region. To serve as a procedural control, a colored line will always appear at the control line region if the test has been performed properly.
More Information

No
The device description and performance studies indicate a simple lateral flow immunoassay that provides a visual qualitative result based on antigen-antibody binding, without any mention of computational analysis, algorithms, or learning processes.

No.

This device is a diagnostic tool used for the qualitative detection of amphetamine in urine and is not intended for treating or preventing disease.

Yes

This device is a rapid immunoassay designed for the qualitative detection of amphetamine in human urine, which serves as a diagnostic tool to identify the presence of the substance.

No

The device description clearly indicates it is a physical test strip and test device that utilizes immunochromatographic assays, which are hardware components, not software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states it's for the "qualitative detection of amphetamine in human urine." This involves testing a sample taken from the human body in vitro (outside the body) to provide information about a physiological state (presence of amphetamine).
  • Device Description: The description details a "rapid chromatographic immunoassay" that utilizes "antigen-antibody immunochemistry" to detect a substance in a urine sample. This is a classic description of an in vitro diagnostic test.
  • Sample Type: The test is performed on "human urine," which is a biological specimen.
  • Purpose: The purpose is to detect the presence of amphetamine, which is a substance that can indicate drug use or exposure, providing diagnostic information.

The information provided aligns perfectly with the definition of an In Vitro Diagnostic device.

Summary of Performance Studies

Accuracy: A clinical evaluation was conducted using 300 specimens. Ten percent of these clinical specimens were enriched at +/- 25% levels of the cut-off concentration of 1,000 ng/mL. The ACON AMP One Step Amphetamine Test Strip and ACON AMP One Step Amphetamine Test Device were compared to the LifeSign Status DS AMP One-Step Amphetamine Test and Gas Chromatography/Mass Spectrometry (GC/MS).

Results for ACON AMP One Step Amphetamine Test Strip compared to LifeSign Status DS™ AMP One-Step Amphetamine Test:
Positive Agreement: 141 / 146 = 97%
Negative Agreement: 154 / 154 = 100%
Overall Agreement: 295 / 300 = 98%

Results for ACON AMP One Step Amphetamine Test Device compared to LifeSign Status DS™ AMP One-Step Amphetamine Test:
Positive Agreement: 140 / 146 = 96%

Overall Agreement: 294 / 300 = 98%

Results for ACON AMP One Step Amphetamine Test Strip compared to GC/MS:
Positive Agreement: 132 / 136 = 97% (93 - 99%)
Negative Agreement: 155 / 164 = 95% (90 - 93%)
Total Agreement: 287 / 300 = 96% (93 - 98%)

Results for ACON AMP One Step Amphetamine Test Device compared to GC/MS:

Sensitivity: Tested amphetamine concentrations at 0, 500, 750, 1,000, 1,250, 1,500, and 2,000 ng/mL. Each concentration level was tested in 30 replicates for both devices. The data indicate 100% positive results at 125% and 150% above the cut-off concentration of 1,000 ng/mL, and 100% negative results at 50% below the cut-off concentration of 1,000 ng/mL.

Specificity: Specificity studies were conducted by individually spiking various amphetamine related compounds and metabolites into drug-free urine. Samples were diluted sequentially until the lowest concentration that yielded a positive result was identified. Examples given are D-Amphetamine (1,000 ng/mL, 100% cross reactivity), L-Amphetamine (50,000 ng/mL, 2% cross reactivity), D,L-Amphetamine (3,000 ng/mL, 33% cross reactivity), (+, -) - 3,4- Methylenedioxyamphetamine (MDA) (2,000 ng/mL, 50% cross reactivity), and Phentermine (3,000 ng/mL, 33% cross reactivity).

Interfering Substances: No interference was observed when testing negative or positive specimens containing listed substances at a final concentration of 100 ug/mL. Examples include 4-Acetamidophenol, Acetaphenetidine, Acetylsalicylic acid, Aminopyrine, Amitryptyline, Amobarbital, Caffeine, Cortisone, Creatinine, Dextromethorphan, Digoxin, Diphenhydramine, Ibuprofen, Morphine-3-B-D-Glucuronide, Phencyclidine, Prednisolone, Quinidine, Salicylic Acid, and Sulfamethazine.

Intra and inter-assay variability: Both the ACON Amphetamine Test Strip and Test Device demonstrated a high level of precision within run, between run and between days.
