The device description details a process based on detecting color intensity and applying a stored calibration curve determined by nonlinear regression. There is no mention of AI or ML algorithms for image analysis, pattern recognition, or decision-making beyond this pre-defined curve.
No
The device is described as an in vitro diagnostic (IVD) system used for screening drugs of abuse in urine samples, providing qualitative results for diagnostic purposes, not for direct treatment or prevention of disease.
Yes
Explanation: The device is intended for "Drugs of Abuse Screening Tests" to provide "qualitative screening results" for specific substances in human urine. It is explicitly stated as being "For In Vitro Diagnostic Use," and its function is to detect and quantify substances (drugs) to aid in diagnosis or screening.
No
The device description explicitly states that the system includes a "UNISCAN-DoA scanner," which is described as a "scientific measurement device" with a "contact image sensor (CIS) inside the device." This indicates the presence of hardware components beyond just software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section explicitly states: "For In Vitro Diagnostic Use."
- Nature of the Test: The device is designed to test human urine specimens for the presence of drugs of abuse. This is a classic example of an in vitro diagnostic test, as it analyzes a biological sample outside of the body to provide information about a person's health status (in this case, the presence of certain substances).
- Intended Use: The intended use is for "Drugs of Abuse Screening Tests," which falls under the scope of IVD devices.
- Professional Use: The device is intended for use in a "laboratory by professional personnel," which is a common setting for IVD testing.

Intended Use / Indications for Use
This mAMP/Opi/THC panel test is a prescription assay intended for use with UNISCAN-DoA scanner in laboratory by professional personnel. The mAMP/Opi/THC assays were calibrated with d-methamphetamine/morphine/11-nor-△9-THC-9-COOH, respectively. It provides qualitative screening results for Methamphetamine/ Opiate/cannabinoids in human urine at a cutoff concentration of 1000/300/50 ng/ml. 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.

Intended Use: This mAMP/Opi/THC panel test is a prescription assay intended for use with UNISCAN-DoA scanner in laboratory by professional personnel. The mAMP/Opi/THC assays were calibrated with
1
d-methamphetamine/morphine/11-nor-△9-THC-9-COOH, respectively. It provides qualitative screening results for Methamphetamine/ Opiate/cannabinoids in human urine at a cutoff concentration of 1000/300/50 ng/ml. 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.
Technology: UNISCAN-DoA system, like multi-drug tests from other manufacturer such as Roche, American Biotech Inc, and Forefront Diagnostic Inc, etc., detects the presence of target drugs or their metabolites by one step, chromatographic, and competitive immunoassay technology. Currently marketed Triage TOX Drug Screen (whose 510(k) number is K043242) is used for substantial equivalence predicate kit. All of these products are based on the same immunochemical principle of recognition and formation of specific antibody / target drug / antibody / complexes.
The device contains a membrane strip, which is pre-coated with drug-protein conjugate at the test region of the membrane strip. A wicking pad containing anti-drug monoclonal antibody-conjugate is placed at one end of the membrane. The device contains a control region which has a different antigen/antibody from the test region.
The assay relies on the competition for binding antibody between drug conjugate and free drug that may be present in the urine specimen being tested. When drug is present in the urine specimen, it competes with drug conjugate for limited amount of antibody-colloidal gold conjugate. If the drug is present in the urine specimen, it will prevent the binding of drug conjugate to the antibody. Therefore, the color intensity of the test line is reduced. The higher the drug concentration is present in the urine specimen, the lower the color intensity is in the test line of a strip. The color intensity of a test line is inversely proportional to the drug concentration in the urine specimen. The correlation between the color intensity and the drug concentration is described by a calibration curve, whose coefficients are determined via nonlinear regression based on the experimental data. The calibration curve equation and its coefficients are stored in UNISCAN-DoA scanner. Once a developed test strip is inserted into the
2
scanner and is scanned by the device, the color intensity of a test line is detected by the contact image sensor (CIS) inside the device and the signal is converted to drug concentration according to the stored calibration curve equation and its coefficients. The qualitative result is then displayed on the LCD screen of the device.
A control line is present at the control region to work as procedural control. This colored band should always appear at the control region regardless the presence of drugs or metabolite. The UNISCAN-DoA scanner automatically detects the color intensity of a control line. If the control line of an inserted test strip does not be detected by the device, "Strip is Failed!" will be displayed on the LCD screen of the device.
Performance: The product performance characteristics of UNISCAN-DoA system was evaluated in studies. The results of these studies demonstrated that UNISCAN-DoA system can be performed by professional and laboratory personnel to obtain a qualitative and rapid detection of drugs of abuse.

Conclusion: Both subject and predicate device Triage TOX Drug Screen (whose 510(k) number is K043242) are qualitative immunochromatographic single-use tests for measurement of the same analyte(s) in the same matrix. Both subject and predicate devices are competitive immunoassays.
The studies demonstrate the substantial equivalence of Uniscan-DoA system to existing products already marketed for screening drugs of abuse. The safety and effectiveness of the subject are established and it is appropriate for commercial distribution.
