Intended Use

The Immunalysis Methamphetamine ELISA test system utilizes an Enzyme Linked Immunoassay (ELISA) for the qualitative detection of methamphetamine in ORAL FLUID SAMPLES COLLECTED WITH THE QUANTISAL™ ORAL FLUID COLLECTION DEVICE ONLY using a cutoff of 50 ng/mL of d-methamphetamine. This in vitro diagnostic device is intended for clinical laboratory use only. The Immunalysis Methamphetamine ELISA Kit for Oral Fluids provides only a preliminary analytical test result. A more specific alternate chemical must be used in order to obtain a confirmed analytical result. Gas chromatography/ mass spectrometry (GS-MS) is the preferred confirmatory method . Clinical and Professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.

Device Story

In vitro diagnostic ELISA test system for qualitative detection of methamphetamine in oral fluid. Input: oral fluid samples collected using Quantisal device. Principle: Enzyme Linked Immunoassay (ELISA) targeting d-methamphetamine at 50 ng/mL cutoff. Output: preliminary analytical result. Used in clinical laboratory settings by trained personnel. Results require confirmation via alternate chemical method, preferably Gas Chromatography/Mass Spectrometry (GC-MS). Clinical judgment required for interpretation of preliminary positive results.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Qualitative ELISA immunoassay. Components: cellulose collection pad, propylene stem, polypropylene buffer tube, rabbit polyclonal antibody-coated microstrips, TMB substrate. Energy source: spectrophotometer (450/620 nm). Connectivity: standalone. Sterilization: not specified.

Indications for Use

Indicated for qualitative detection of methamphetamine in oral fluid samples from patients suspected of drug use. Intended for clinical laboratory use only. Preliminary results require confirmation via GC-MS.

Regulatory Classification

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.

Special Controls

*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).

Trade/Device Name: Immunalysis Methamphetamine ELISA for Oral Fluids Regulation Number: 21 CFR 862.3610 Regulation Name: Methamphetamine test system Regulatory Class: Class II Product Code: LAF Dated: August 10, 2005 Received: August 23, 2005

Dear Mr. Vincent:

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 your 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 (QS) regulation (21 CFR Part 820).
