Intended Use
The Amedica Drug Screen Methamphetamine Test is a immunochromatographic assay for the rapid detection of methamphetamine in human urine at a cutoff concentration of 1000 ng/ml. This assay has not been evaluated at point-of-care locations and is intended for use by healthcare professionals. This assay provides only a preliminary result. A more specific alternative chemical method is needed to obtain a confirmed result.
Device Description
Membrane based one-step, lateral flow, competitive immunoassay use colloidal gold for visual detection. The test cutoff is 1000 ng/ml.

No
The description details a standard immunoassay with visual detection and does not mention any AI or ML components.

No
The device is a diagnostic test for detecting methamphetamine in urine; it does not provide any treatment or therapy.

Yes

The device is an "immunochromatographic assay for the rapid detection of methamphetamine in human urine," which indicates its use in identifying a substance related to health status.

No

The device description clearly indicates a "membrane based one-step, lateral flow, competitive immunoassay use colloidal gold for visual detection," which describes a physical test strip and associated components, not a software-only device.

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

Here's why:

  • Intended Use: The intended use clearly states it's for the "rapid detection of methamphetamine in human urine." This involves testing a sample taken from the human body in vitro (outside the body).
  • Device Description: The description of the device as an "immunochromatographic assay" that uses "human urine" as the sample further confirms its nature as a diagnostic test performed on a biological specimen.
  • Performance Studies: The description of performance studies using "clinical specimens" and comparison to a reference method (GC/MS) is typical for IVD devices.

The key characteristic of an IVD is that it's used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or screening purposes. This device fits that description perfectly.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The product performance was evaluated by correlation study using blind-labeled clinical specimens that have been measured by GC/MS. This study produced > 94% agreement with GC/MS results. In addition, clinical site study was performed at two certified laboratories and demonstrated that Amedica Biotech Drug Screen Methamphetamine Test can be use by professionals to obtain a visual, qualitative detection of drugs of abuse. The results of these study and comparison with Rapid Diagnostics methamphetamine test demonstrated that Amedica Biotech Drug Screen Methamphetamine Test is substantially equivalent to the predicate kit.

§ 862.3610 Methamphetamine test system.

(a)
Identification. A methamphetamine test system is a device intended to measure methamphetamine, a central nervous system stimulating drug, in serum, plasma, and urine. Measurements obtained by this device are used in the diagnosis and treatment of methamphetamine use or overdose.(b)
Classification. Class II (special controls). A methamphetamine 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).

DEC 1 6 2002

Device name: Amedica Drug Screen Methamphetamine Test

Design and Materials: Membrane based one-step, lateral flow, competitive immunoassay use colloidal gold for visual detection. The test cutoff is1000 ng/ml.

Intended Use: The Amedica Drug Screen Methamphetamine Test is a immunochromatographic assay for the rapid detection of methamphetamine in human urine at a cutoff concentration of 1000 ng/ml. This assay has not been evaluated at point-of-care locations and is intended for use by healthcare professionals.

This assay provides only a preliminary result. A more specific alternative chemical method is needed to obtain a confirmed result.

Test Principle and Description: The Amedica Drug Screen Methamphetamine Test is based on the principle of highly specific competitive immunochemical reactions between antigens and antibodies for the analysis of specific substances in urine. During testing, a urine specimen moves along membrane on the strip by capillary action. When methamphetamine concentration in the urine is below 1000 ng/ml, it is not enough to saturate all of the binding sites of the antibody-coated colored particles in the test strip. The unsaturated antibody-coated particles will then be captured by methamphetamine conjugates immobilized on the strip and a colored line will appear in the test line region. The test result is negative. If the methamphetamine level is above 1000 ng/ml, it is sufficient to occupy all of the binding sites on the antibody-coated particles. The saturated antibody-coated particles will not be captured by methamphetamine conjugate coated on the strip. The colored line will not form in the test region. The test result is positive. The device also provides a built-in control with a different antibody reaction at the control region. This control line should always appear whether or not the drugs or metabolites are present. If the control line does not appear the test cartridge should be discarded. This means that negative urine will produce two colored bands, and positive urine will produce only one band at control region

Performance: The product performance was evaluated by correlation study using blind-labeled clinical specimens that have been measured by GC/MS. This study produced > 94% agreement with GC/MS results. In addition, clinical site study was performed at two certified laboratories and demonstrated that Amedica Biotech Drug Screen Methamphetamine Test can be use by professionals to obtain a visual, qualitative detection of drugs of abuse. The results of these study and comparison with Rapid Diagnostics methamphetamine test demonstrated that Amedica Biotech Drug Screen Methamphetamine Test is substantially equivalent to the predicate kit.

Dear Mr. Chen:

Re:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). 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 (PMA). it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that vour device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820).
