Intended Use
The Wondfo CR3 Keyless Split Sample Cup is a competitive binding, lateral flow immunochromatographic assay for qualitative and simultaneous detection of Amphetamine, Secobarbital, Oxazepam, Cocaine, Cannabinoids, Methamphetamine, Methylenedioxymethamphetamine, Morphine, Phencyclidine, Oxycodone, Buprenorphine, Methadone and Notriptyline in human urine at the cutoff concentrations of: Drug(Identifier) Cut-off level Amphetamine(AMP) 1000 ng/mL Secobarbital (BAR) 300 ng/mL Oxazepam (BZO) 300 ng/mL Cocaine (COC) 300 ng/mL Cannabinoids (THC) 50 ng/mL Methamphetamine (MET) 1000 ng/mL Methylenedioxymethamphetamine (MDMA) 500 ng/mL Morphine (MOP) 300 or 2000 ng/mL Phencyclidine (PCP) 25 ng/mL Oxycodone (OXY) 100 ng/mL Buprenorphine (BUP) 10 ng/mL Methadone (MTD) 300 ng/mL Notriptyline (TCA) 1000 ng/mL Configuration of the Wondfo CR3 Keyless Split Sample Cup can consist of any combination of the above listed drug analytes. The test provides only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. GC/MS is the preferred confirmatory method. The test will yield preliminary positive results when prescription drugs Buprenorphine, Oxazepam, Oxycodone and Secobarbital are ingested, even at or above therapeutic doses. It is not intended to distinguish between prescription use or abuse of these drugs. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive.
Device Story
Wondfo CR3 Keyless Split Sample Cup; lateral flow immunochromatographic assay for qualitative detection of drugs of abuse in human urine. Device uses competitive binding principle; mouse monoclonal anti-drug antibody-dye conjugates; fixed drug-protein conjugates; anti-mouse IgG polyclonal antibodies on test membranes. Urine sample absorbed via capillary action; mixes with antibody-dye conjugate. Analyte below cutoff: antibody-dye binds to immobilized drug-protein in Test Region (T); colored line indicates negative result. Analyte above cutoff: analyte binds antibody-dye; prevents binding to Test Region; no colored line indicates preliminary positive. Control line (C) confirms proper flow. Used in clinical or home settings; operated by clinicians or lay users. Provides preliminary results; requires confirmatory testing (GC/MS or LC/MS). Aids in identifying potential drug presence; clinical judgment required for interpretation.
Clinical Evidence
Bench testing only. Performance established via verification studies supporting the multi-drug cup configuration (2-13 drugs). Includes interference studies and a lay-user study. Analytical performance metrics for individual drug analytes were previously established in the cited predicate 510(k) submissions.
Technological Characteristics
Lateral flow immunochromatographic assay; competitive binding principle. Components: mouse monoclonal anti-drug antibody-dye conjugate, fixed drug-protein conjugates, anti-mouse IgG polyclonal antibodies. Form factor: split sample cup. Connectivity: none. Sterilization: not specified.
Indications for Use
Indicated for qualitative, simultaneous detection of Amphetamine, Secobarbital, Oxazepam, Cocaine, Cannabinoids, Methamphetamine, MDMA, Morphine, Phencyclidine, Oxycodone, Buprenorphine, Methadone, and Notriptyline in human urine. Intended for both prescription and OTC use. Not intended to distinguish between prescription use and abuse.
Regulatory Classification
Identification
An opiate test system is a device intended to measure any of the addictive narcotic pain-relieving opiate drugs in blood, serum, urine, gastric contents, and saliva. An opiate is any natural or synthetic drug that has morphine-like pharmocological actions. The opiates include drugs such as morphine, morphine glucoronide, heroin, codeine, nalorphine, and meperedine. Measurements obtained by this device are used in the diagnosis and treatment of opiate use or overdose and in monitoring the levels of opiate administration to ensure appropriate therapy.
Special Controls
*Classification.* Class II (special controls). An opiate 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).

- 6. Description of the device:
{5}------------------------------------------------
The Wondfo CR3 Keyless Split Sample Cup uses immunochromatographic assays for qualitative and simultaneous detection of Amphetamine, Secobarbital, Oxazepam, Cocaine, Cannabinoids, Methamphetamine, Methylenedioxymethamphetamine, Morphine, Phencyclidine, Oxycodone Buprenorphine, Methadone and Notriptyline in human urine samples. The test is a lateral flow, competitive binding system. The test is the first step in a two-step process. The second step is to send the sample for laboratory testing if preliminary positive results are obtained.
- 7. Test Principle
The Wondfo CR3 Keyless Split Sample Cup is a rapid test for the qualitative detection of Amphetamine, Secobarbital, Oxazepam, Cocaine, Cannabinoids, Methamphetamine, Methylenedioxymethamphetamine, Morphine, Phencyclidine, Oxycodone Buprenorphine, Methadone and Notriptyline in urine samples and contains lateral flow chromatographic immunoassays for these analytes. Each assay uses a mouse monoclonal anti-drug antibody-dye conjugate, fixed drug-protein conjugates, and anti-mouse IgG polyclonal antibodies coated on the test membranes. When the absorbent end of the test is immersed into a urine sample, the urine is absorbed into the device by capillary action and mixes with the antibody-dye conjugate, flowing across the pre-coated membrane. At analyte concentrations below the target cut-off, antibody-dye conjugates bind to the drug-protein conjugate immobilized in the Test Region (T) of the device. This produces a colored test line that indicates a negative result. When analyte concentration is above the cut-off, analyte molecules bind to the antibody-dye conjugate, preventing the antibody-dye conjugate from binding to the drug-protein conjugate immobilized in the Test Region (T) of the device. No colored band shows in the test region, indicating a potentially positive result. A band should form in the control region (C) of the device regardless of the presence of drug or metabolite in the sample.
- 8. Intended use of the device:
The Wondfo CR3 Keyless Split Sample Cup is a competitive binding, lateral flow immunochromatographic assay for qualitative and simultaneous detection of Amphetamine, Secobarbital, Oxazepam, Cocaine, Cannabinoids, Methamphetamine, Methylenedioxymethamphetamine, Morphine, Phencyclidine, Oxycodone, Buprenorphine, Methadone and Notriptyline in human urine at the cutoff concentrations of:

Configuration of the Wondfo CR3 Keyless Split Sample Cup can consist of any combination of the
{6}------------------------------------------------
above listed drug analytes.
The test provides only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. GC/MS is the preferred confirmatory method.
The test will yield preliminary positive results when prescription drugs Buprenorphine, Oxazepam, Oxycodone and Secobarbital are ingested, even at or above therapeutic doses. It is not intended to distinguish between prescription use or abuse of these drugs.
Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive.
