Indications for Use
DAT Oral Fluid Methamphetamine (OFMA) is an in vitro diagnostic test for the qualitative and semiquantitative detection of methamphetamine in human oral fluid at a cutoff concentration of 120 ng/mL in neat oral fluid. The specimen must be collected exclusively with the Intercept® Oral Specimen Collection Device. Semiguantitative test results may be obtained that permit laboratories to assess assay performance as part of a quality control program and to estimate a dilution of the specimen for confirmation by a confirmatory method such as LC/MS/MS. DAT Oral Fluid Methamphetamine provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Chromatography/mass spectrometry is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used. The Oral Fluid DAT Control Set A is for use as assayed controls with the DAT Oral Fluid assays on automated clinical chemistry analyzers for human oral fluid samples collected with the Intercept Oral Specimen Collection Device. The Oral Fluid DAT Qual Cal calibrators are designed for the calibration of oral fluid assays for drugs of abuse on automated clinical chemistry analyzers for human oral fluid samples collected with the Intercept Oral Specimen Collection Device. The Oral Fluid DAT SQ Cal A calibrators are designed for the calibration of oral fluid assays for drugs of abuse on automated clinical chemistry analyzers for human oral fluid samples collected with the Intercept Oral Specimen Collection Device.
Device Story
In vitro diagnostic assay for methamphetamine detection in human oral fluid; utilizes Kinetic Interaction of Microparticles in Solution (KIMS) technology. Input: oral fluid sample collected via Intercept® device. Principle: drug in sample competes with drug-derivative conjugate for microparticle-bound antibody; inhibition of particle lattice formation reduces absorbance proportional to drug concentration. Output: qualitative or semiquantitative result on automated clinical chemistry analyzers. Used in clinical laboratories by technicians; results provide preliminary analytical data requiring confirmation by chromatography/mass spectrometry (e.g., LC/MS/MS). Assists healthcare providers in drug abuse screening; clinical judgment required for interpretation.
Clinical Evidence
No clinical data provided; substantial equivalence based on analytical performance characteristics and comparison to predicate device.

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).
