The device description and performance studies detail a standard enzyme immunoassay method and do not mention any AI or ML components.
No.
This device is an in vitro diagnostic (IVD) test for the qualitative and semi-quantitative determination of d-methamphetamine in human oral fluid. It is used for diagnostic purposes and not for treating or preventing disease.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is "intended for the qualitative and semi-quantitative determination of d-methamphetamine in neat human oral fluid," which is a diagnostic purpose.
No
The device is a kit containing chemical reagents (R1 and R2 solutions), calibrators, controls, and a physical oral fluid collector. It is an enzyme immunoassay, which is a laboratory test method involving chemical reactions, not solely 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 and semi-quantitative determination of d-methamphetamine in neat human oral fluid". This is a diagnostic test performed on a biological sample (oral fluid) to detect the presence and approximate amount of a substance (methamphetamine).
- Sample Type: It uses "human oral fluid", which is a biological specimen.
- Method: It employs an "Enzyme Immunoassay", which is a common in vitro diagnostic technique.
- Purpose: The purpose is to provide a "preliminary analytical result" for the presence of methamphetamine, which is a diagnostic step in identifying drug use.
- Components: The device includes reagents, calibrators, and controls, which are typical components of an IVD kit used for testing biological samples.
- Care Setting/User: It is intended for "prescription use with a number of automated clinical chemistry analyzers" and used by professionals, indicating it's for use in a clinical laboratory setting.
All these factors align with the definition of an In Vitro Diagnostic device, which is a medical device intended for use in vitro for the examination of specimens derived from the human body solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to monitor therapeutic measures.
N/A
Intended Use / Indications for Use
The LZI Oral Fluid Methamphetamine Enzyme Immunoassay is intended for the qualitative and semi-quantitative determination of d-methamphetamine in neat human oral fluid, collected into the LZI Oral Fluid Collector, at the cutoff value 50 ng/mL. The assay is designed for prescription use with a number of automated clinical chemistry analyzers.
The semi-quantitative mode is for purposes of (1) enabling laboratories to determine an appropriate dilution of the specimen for confirmation by a confirmatory method such as GCMS and LCMS or (2) permitting laboratories to establish quality control procedures.
The LZI Oral Fluid Methamphetamine Calibrators are for use as calibrators in the qualitative and semi-quantitative calibration of the LZI Oral Fluid Methamphetamine Enzyme Immunoassay at the cutoff value 50 ng/mL.
The LZI Oral Fluid Methamphetamine Controls are for use as assayed quality control materials to monitor the precision of the LZI Oral Fluid Methamphetamine Enzyme Immunoassay at the cutoff value of 50 ng/mL.
The assay provides only a preliminary analytical result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas or liquid chromatography|mass spectrometry (GC|MS or LC|MS) is the preferred confirmatory method). Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary test result is positive.

Device Description
The LZI Oral Fluid Methamphetamine assay is a homogeneous enzyme immunoassay with ready-to-use liquid reagent. The assay is based on competition between drug in the sample and drug labeled with the enzyme glucose-6-phosphate dehydrogenase (G6PDH) for a fixed amount of antibody in the reagent. Enzyme activity decreases upon binding to the antibody, and the drug concentration in the sample is measured in terms of enzyme activity. In the absence of drug in the sample, methamphetamine-labeled G6PDH conjugate is bound to antibody, and the enzyme activity is inhibited. On the other hand, when free drug is present in the sample, antibody would bind to free drug, the unbound methamphetamine-labeled G6PDH then exhibits its maximal enzyme activity. Active enzyme converts nicotinamide adenine dinucleotide (NAD) to NADH, resulting in an absorbance change that can be measured spectrophotometrically at 340 nm.
The LZI Oral Fluid Methamphetamine Enzyme Immunoassay is a kit comprised of two reagents, an R1 and R2 which are bottled separately but sold together within the kit.
The R1 solution contains mouse monoclonal anti-methamphetamine antibody, glucose-6phosphate (G6P) nicotinamide adenine dinucleotide (NAD), stabilizers, and sodium azide (0.09%) as a preservative. The R2 solution contains glucose-o-phosphate dehydrogenase (G6PDH) labeled with methamphetamine in buffer with sodium azide (0.09%) as preservative.
The LZI Oral Fluid Methamphetamine Enzyme Immunoassay calibrators and controls designated for use at the 50 ng/mL cutoffs contain 0, 20, 37.5, 50, 62.5, 100, and 140 ng/mL of dmethamphetamine in human oral fluid with sodium azide (0.09%) as preservative. These five calibrators and two controls are sold as individual bottles.
The LZI Oral Fluid Collector is a 50 mL polypropylene collection tube. It is a non-sterile centrifuge tube with a screw-on cap and printed graduations (United Lab Plastics, Catalog#UP2262).
