Kennel Consultant NJK & Associates, Inc. 13721 Via Tres Vista San Diego, CA 92129 Phone: (858) 705-0350 Fax: (858) 764-9739 email: NKennel@njkconsulting.com Date Prepared: Dec. 23, 2008 # DEVICE INFORMATION Trade/Proprietary Name; RapidSense™ Drugs of Abuse Methamphetamine (MET) 1000 device Common Name: Methamphetamine assay 21 CFR 862.3610 Class II Product Code: LAF # Intended Use: The RapidSense™ Drugs of Abuse Methamphetamine (MFT) 1000 Device is a lateral flow competitive immunoassay intended for the qualitative detection of Methamphetamine in human urine at a cut-off concentration of 1000 ng/mL. The assay is intended for use in professional laboratories by healthcare professionals. For in vitro diagnostic use. This assay provides only a preliminary result. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly in evaluating a preliminary positive result. To obtain a confirmed analytical result, a more specific alternate chemical method is needed. Gas chromatography/mass spectroscopy (GC/MS) is the recommended confirmatory method. Tests for methamphetamine cannot distinguish between abused drugs and certain prescribed medications. Certain foods or medications may interfere with tests for methamphetamine and cause false positive results. {1}------------------------------------------------ ### Product Description: The RapidSense™ Drugs of Abuse Methamphetamine (MET) 1000 Device is an immunoassay based on the principle of competitive binding. Methamphetamine which may be present in the urine specimen competes against its respective drug conjugate for binding sites on the specific antibody. The assay is a colored-latex particle, monoclonal antibody-based rapid test for the qualitative detection of Methamphetamine at a cut-off of 1000 ng/mL. The test utilizes the QuantRx patented, one step positive read, competitive immunoassay technology. In the absence of the drug in the urine or if the amount of drug is below cut-off level, the visible test line zone (T) will show a clean negative (no signal on the test band). Drug positive specimens show a blue line in the visible test line zone (T). As an internal procedural control, a red control line appears in the control region (C) to verify that sufficient volume of sample was added and proper flow was obtained. The control line should always appear regardless of the presence of the drug if the assay has been performed properly. ## Predicate Device: ACON mAMP One Step Methamphetamine Test Strip & Test Device 510(k) Number K011672 #### Comparison to Predicate Device Both the RapidSense™ Drugs of Abuse Methamphetamine (MET) 1000 device and the ACON mAMP One Step Methamphetamine Test Device, cleared under K011672 have the indications for use and same cut-off of 1000 ng/mL. Both assays are lateral flow competitive immunoassays which provide a visual qualitative end point. Both assays are intended as a screening method that provides a preliminary test result. The RapidSense™ Drugs of Abuse Methamphetamine (MET) 1000 device differs from the ACON mAMP One Step Methamphetamine Test Device in that the RapidSense™ device is a positive read test and the ACON device is a negative read test. #### Summary of Safety and Effectiveness Data: #### Accuracy: The RapidSense™ Drugs of Abuse Methamphetamine (MET) 1000 Device was compared to the reference method of Gas chromatography/mass spectrometry (GC/MS) on 84 specimens previously collected from subjects presenting for drug testing by an external laboratory. Methamphetamine was quantified by GC/MS with a cut-off of 1000 ng/mL as well as compared to the predicate device. The results of the study were as follows: RapidSense TM Drugs of Abuse Methamphetamine (MET) 1000 Device compared to GC/MS. Positive Agreement: 33/44 = 75.0% (60.6 to 85.4%*) {2}------------------------------------------------ # Negative Agreement: 40/40 =100% (91.2 to 100.0%*) Total Agreement: 73/84 = 86.9% (78.1 to 92.5%*) * 95% Confidence intervals The results of the predicate device to GCMS showed similar performance. # Conclusion: These studies demonstrate the substantial equivalence of the RapidSense™ Drugs of Abuse Methamphetamine (1000) device to the ACON mAMP One Step Methamphetamine Test Device. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services. The logo features a stylized eagle with its wings spread, and the words "DEPARTMENT OF HEALTH & HUMAN SERVICES - USA" are arranged in a circular pattern around the eagle. The logo is black and white.
