Intended Use

The Quidel Triage® TOX Drug Screen, 94600 is a fluorescence immunoassay to be used with the Quidel Triage® MeterPro for the qualitative determination of the presence of drugs and/or metabolites in human urine of up to 9 drug assays at or above the threshold concentrations. The threshold concentrations are provided below: AMP (Amphetamines) 500 ng/mL, mAMP (Methamphetamines) 500 ng/mL, BAR (Barbiturates) 200 ng/mL, BZO (Benzodiazepines) 200 ng/mL, COC (Cocaine) 150 ng/mL, EDDP (Methadone Metabolite) 100 ng/mL, OPI (Opiates) 300 ng/mL, THC (Cannabinoids) 50 ng/mL, TCA (Tricyclic Antidepressants) 1000 ng/mL. This test provides only a preliminary test result. Clinical consideration and professional judgment must be applied to any drug test result, particularly in evaluating a preliminary positive result. A more specific alternate chemical must be used to obtain a confirmed analytical result. Gas Chromatography / Mass Spectroscopy (GC/MS), Liquid Chromatography / Mass Spectroscopy / Mass Spectroscopy (LC-MS/MS) and High Performance Liquid Chromatography (HPLC) are common confirmatory methods.

Device Story

Single-use lateral flow immunofluorescence test device; used with Quidel Triage® MeterPro. Input: human urine specimen. Principle: competitive immunoassay; urine flows through filter; reacts with fluorescent antibody/drug conjugates; capillary action moves mixture through device. Presence of drug prevents binding of fluorescent conjugates to solid phase; unbound conjugates washed into waste reservoir. MeterPro measures fluorescence in measurement zones; displays results in ~15 minutes. Used in clinical settings; operated by healthcare professionals. Output: qualitative preliminary drug presence/absence. Results stored in meter; can be transmitted to hospital information systems. Assists clinicians in rapid drug screening; requires confirmatory testing for positive results.

Clinical Evidence

No clinical data. Bench testing only. Analytical specificity study performed to evaluate cross-reactivity of four additional compounds (Metharbital, p-Hydroxyphenobarbital, Talbutal, Alprazolam glucuronide-OH) on the Triage TOX Drug Screen device.

Technological Characteristics

Lateral flow immunoassay. Qualitative detection of drug analytes in urine. Device form factor and fundamental scientific technology remain consistent with the previously cleared predicate. No changes to materials or energy sources.

Indications for Use

Indicated for the qualitative detection of drugs of abuse in human urine, including amphetamines, methamphetamines, barbiturates, benzodiazepines, cocaine/metabolites, methadone, opiates, cannabinoids, and tricyclic antidepressants.

Regulatory Classification

Identification

An amphetamine test system is a device intended to measure amphetamine, a central nervous system stimulating drug, in plasma and urine. Measurements obtained by this device are used in the diagnosis and treatment of amphetamine use or overdose and in monitoring levels of amphetamine to ensure appropriate therapy.

Special Controls

*Classification.* Class II (special controls). An amphetamine 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).

Test Principle: The Quidel Triage TOX Drug Screen, 94600 is a test device utilizing the standard Triage technology. It is a competitive fluorescence immunoassay which contains all the reagents necessary for the qualitative detection, relative to an assigned threshold value, of the major urinary metabolites for the following substances in human urine: amphetamine (AMP), methamphetamine (mAMP), barbiturates (BAR), benzodiazepines (BZO), cocaine (COC), methadone/methadone metabolite (EDDP), opiates (OPI), tetrahydrocannabinol (THC), and tricyclic antidepressants (TCA). The Test Device contains: - Murine monoclonal antibodies against 9 targeted drugs or metabolites ● - Fluorescently labeled antibodies - Fluorescently labeled metabolites ● - Solid phase - Stabilizers ● The test procedure involves the addition of a urine specimen to the sample port on the Test Device. After addition of the specimen, the urine passes through a filter. The specimen reacts with fluorescent antibody conjugates or with fluorescent drug conjugates and flows through the Test Device by capillary action. The presence of drug or drug metabolite in the urine specimen prevents binding of the fluorescent conjugates to the solid phase on the detection zone. Excess urine washes the unbound fluorescent conjugates from the detection lane into a waste reservoir. The Test Device is inserted into the Quidel Triage MeterPro. The Quidel Triage MeterPro is programmed to perform the analysis after the specimen has reacted with the reagents in the Test Device. The analysis is based on the amount of fluorescence the Quidel Triage MeterPro detects within a measurement zone on the Test Device. The positive results are displayed on the Quidel Triage MeterPro screen in about 15 minutes. All results are stored in the Quidel Triage MeterPro memory to display or print when needed. If connected, the Quidel Triage MeterPro can transmit results to the laboratory or hospital information system. #### Performance Characteristics: 1.13. - 1.
