Indications for Use
This device is a one-step immunoassay intended to provide qualitative detection of methylenedioxymethamphetamine (MDMA, also Ecstasy, or XTC) in human urine at a cutoff concentration of 500ng/ml. It is for health care professional use only. This test provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas Chromatography/Mass Spectrometry (GC/MS) 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.
Device Story
Instant-View™ MDMA Urine Test is a lateral flow chromatographic immunoassay for qualitative detection of MDMA in human urine. Device consists of a test strip with a conjugate pad containing colloidal gold-labeled mouse anti-MDMA antibody and a nitrocellulose membrane with a test line (MEMA-BSA) and a control line (Goat anti-mouse antibody). Used in clinical settings by healthcare professionals; provides preliminary results. Sample application triggers capillary flow; competitive binding occurs between MDMA in urine and immobilized MEMA-BSA for gold-labeled antibodies. Absence of test line indicates positive result; presence of control line validates test performance. Results require confirmation via GC/MS. Assists clinicians in identifying potential MDMA presence to guide further diagnostic or clinical management.
Clinical Evidence
Accuracy evaluated using 80 clinical urine specimens compared against GC/MS. Overall agreement was 97.5% (100% agreement at levels <75% of cutoff and >cutoff; 2 discrepancies observed between 75% and 100% of cutoff). Reproducibility tested at three Physician's Office Laboratories (POL) and one reference lab by personnel with diverse experience; 97.5% agreement achieved. Specificity testing showed cross-reactivity with MDA (2000 ng/mL) and MDEA (1000 ng/mL); no interference from other structurally related compounds at 100 µg/mL.
Technological Characteristics
Lateral flow chromatographic immunoassay. Components: conjugate pad (colloidal gold-labeled mouse anti-MDMA antibody), nitrocellulose membrane (test line: MEMA-BSA; control line: Goat anti-mouse antibody). Qualitative, visual readout. Standalone, single-use device. No external energy source required.
Indications for Use
Indicated for qualitative detection of MDMA (Ecstasy/XTC) in human urine at 500 ng/mL cutoff. For use by healthcare professionals only. Provides preliminary results requiring confirmation by 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).
