No
The summary describes a fluorescence immunoassay read by a meter, with results determined by comparing fluorescence levels to predefined threshold concentrations. There is no mention of AI or ML in the device description, intended use, or performance studies.
No
The device is a diagnostic tool used to detect the presence of drugs and/or metabolites in human urine; it does not provide any therapeutic intervention.
Yes
Explanation: The device is used for the qualitative determination of the presence of drugs and/or metabolites in human urine, which provides information for diagnosis or monitoring purposes. The "Intended Use / Indications for Use" section clearly states its purpose as a preliminary test for the presence of drugs.
No
The device description explicitly states it is a "single use test device" and contains physical components like "murine monoclonal antibody conjugates and drug conjugates labeled with a fluorescent dye or immobilized on the solid phase and stabilizers." It is used in conjunction with a hardware device, the Quidel Triage® MeterPro, which reads the test device. This indicates it is a physical test kit, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "qualitative determination of the presence of drugs and/or metabolites in human urine." This is a classic definition of an in vitro diagnostic test, as it analyzes a biological sample (urine) outside of the body to provide information about a person's health status (in this case, the presence of certain drugs).
- Sample Type: The device uses human urine, which is a biological specimen.
- Method: It employs a "fluorescence immunoassay," which is a common laboratory technique used in IVD testing.
- Device Description: The description details a "single use test device" used with an instrument (Quidel Triage® MeterPro) to perform the analysis. This is typical of IVD systems.
- Performance Studies: The document includes information about "Analytical Specificity" and "cross-reactivity," which are standard performance characteristics evaluated for IVD devices.
- Predicate Device: The mention of a "Predicate Device" (K182719, Quidel Triage TOX Drug Screen, 94600) indicates that this device is being compared to a previously cleared IVD device, a common practice in regulatory submissions for IVDs.
All these elements strongly point to the Quidel Triage® TOX Drug Screen, 94600 being an In Vitro Diagnostic device.
N/A
Intended Use / Indications for 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:
| Abbreviation | Analyte | Calibrator | Cutoff |
|---|---|---|---|
| AMP | Amphetamines | d-Amphetamine | 500 ng/mL |
| mAMP | Methamphetamines | d-Methamphetamine | 500 ng/mL |
| BAR | Barbiturates | Butalbital | 200 ng/mL |
| BZO | Benzodiazepines | Temazepam | 200 ng/mL |
| COC | Cocaine | Benzoylecgonine | 150 ng/mL |
| EDDP | Methadone Metabolite | EDDP | 100 ng/mL |
| OPI | Opiates | Morphine | 300 ng/mL |
| THC | Cannabinoids | 11-nor-9-carboxy-Δ9-THC | 50 ng/mL |
| TCA | Tricyclic Antidepressants | Desipramine | 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.

§ 862.3100 Amphetamine test system.
(a)
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.(b)
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).

1.11. Standard/Guidance Document Referenced:
None referenced.
1.12. 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.
