The description details a lateral flow immunoassay, a standard chemical test, with no mention of AI or ML in its mechanism or performance evaluation.
No.
This device is an immunoassay intended for detecting amphetamine in human urine, providing a preliminary analytical test result. It is not designed to treat, prevent, or diagnose any disease or condition through therapeutic means.
Yes
Explanation: The device is intended to detect amphetamine in human urine, providing a preliminary analytical test result which is a form of diagnosis for the presence of amphetamine.
No
The device description clearly indicates it is a "lateral flow chromatographic immunoassay device," which is a physical test strip and not a software-only product.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for detecting amphetamine in human urine. This is a biological sample taken from the body.
- Method: It's a "qualitative one step lateral flow, competitive binding immunoassay device." Immunoassays performed on biological samples are a common type of IVD.
- Anatomical Site: It specifies "human urine," which is a sample from the human body.
The definition of an IVD generally includes devices used to examine specimens derived from the human body to provide information for diagnostic purposes. This device fits that description by testing a human urine sample to detect the presence of amphetamine.

§ 862.3100 Amphetamine test system.
(a)
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.(b)
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).

| Device Name | Trade Name: Instant-View™ Amphetamine Urine Cassette Test
Common Name: Amphetamine Test
Classification Name: 21 CFR 862.3100, Class II |
| Predicate Device | The Instant-View™ Amphetamine Urine Cassette Test is
substantially equivalent to other legally marketed devices
for the similar intended use. The device used for
comparison study is QuikStrip OneStep Amphetamine Test,
manufactured by Syntron Bioresearch, Inc. with 510(K) #:
K971218, Date of Approval: 05/30/97. |
| Device Description | This test is a one-step lateral flow chromatographic
immunoassay. |
| Intended Use | The Instant-View™ Amphetamine Urine Cassette Test is a
qualitative immunoassay device intended to be used for
detecting Amphetamine in human urine at a cutoff level of
1000 ng/ml. It is for health care professional use only. |
| Summary of the
Similarities to the
Predicate Device | • Intended Use:
Both devices are intended to detect amphetamine in
human urine at a cutoff level of 1000 ng/ml.
• Interpretation of results:
The appearance of only one line - C line, indicates a
positive result, and that the amphetamine level is at a
cutoff level of 1000 ng/ml or higher. And, the |
| | appearance of two lines - both C line and T line indicates a negative result, and that the amphetamine level is below 1000 ng/ml.
Technological Characteristics:
Both devices are one step, qualitative, competitive binding immunoassay test, utilizing the basic immunochemical sandwich assay principle of recognition and formation of specific Amphetamine/Antibody/Amphetamine complexes. |
| Discussion and Conclusion | • The correlation of results from the Instant-ViewTM Amphetamine Urine Cassette Test, and the legally marketed test device compared, is higher than 94.6%. The results from all three POL sites agreed 95.0 %.
• The Accuracy Evaluation results from the Clinical Laboratory and the three Physician's Offices Laboratory conducted by persons with diverse educational backgrounds and working experience agreed 92.2 % with the results expected.
• Based on the results of the Performance Characteristics and Comparison Studies, it may be concluded that the Instant-ViewTM Amphetamine Urine Cassette Test is suitable for use by health care professionals with diverse educational backgrounds and work experiences, and it is substantially equivalent to the existing legally marketed device. |

Dear Ms. Filipina:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

Device Name: Instant-View Amphetamine Urine Cassette Test
Indications For Use:
Instant-View Anıphetamine Urine Cassette Test is a qualitative one step lateral flow, competitive binding immunoassay device intended to be used to detect amphetamine in human urine at a cutoff level of 1000 ng/ml. It is intended for health care professional use only.
This test provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas Chromatography/Mass Spectrophotometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse, particularly when preliminary positive results are used.
