Intended Use
Wondfo T-Cup® Multi-Drug Urine Test Cup tests are competitive binding, lateral flow immunochromatographic assays for qualitative and simultaneous detection of Amphetamine, Buprenorphine, Secobarbital, Oxazepam, Cocaine, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine, Methamphetamine, Methylenedioxymethamphetamine, Morphine, Methadone, Oxycodone, Phencyclidine, Propoxyphene, Nortriptyline and Cannabinoids in human urine at the cutoff concentrations of: [Table of cut-off levels]. Wondfo T-Cup® Multi-Drug Urine Test Cup offers any combinations from 2 to 15 drugs of abuse tests but only one cutoff concentration under same drug condition will be included per device. It is for in vitro diagnostic use only. The tests may yield positive results for the prescription drugs Buprenorphine, Nortriptyline, Oxazepam, Secobarbital, Propoxyphene, and Oxycodone when taken at or above prescribed doses. It is not intended to distinguish between prescription use or abuse of these drugs. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly in evaluating a preliminary positive result. The tests provide only preliminary results. To obtain a confirmed analytical result, a more specific alternate chemical method must be used. GC/MS or LC/MS is the recommended confirmatory method.
Device Story
Rapid, single-use lateral flow immunoassay for qualitative detection of 15 drugs of abuse in human urine. Device consists of test cup with integrated test strips. User collects urine sample in cup; sample migrates via capillary action across membrane. Competitive binding principle: target drug in sample competes with drug-conjugate for limited antibody-coated particle binding sites. Absence of colored test line indicates drug presence above cutoff; presence of line indicates drug absence or concentration below cutoff. Control line confirms proper wicking. Intended for OTC use; results are preliminary and require professional confirmation. Provides rapid screening to assist in clinical decision-making regarding drug use.
Clinical Evidence
No clinical trials performed. Evidence includes analytical performance (precision, specificity, cross-reactivity) and a lay-user study (n=280) across 3 sites. Lay-user study demonstrated acceptable usability and comprehension, with performance consistent with analytical expectations at cutoff concentrations.
Technological Characteristics
Lateral flow immunochromatographic assay; competitive binding principle. Form factor: test cup. Specimen: human urine. No external energy source. Stability: 4-30°C for 24 months. No software or electronic components.
Indications for Use
Indicated for qualitative, simultaneous detection of 15 specific drugs of abuse in human urine. Intended for both prescription and over-the-counter (OTC) use. Not intended to distinguish between prescription use and abuse.
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).

Dear Joe Shia:
This letter corrects our substantially equivalent letter of December 3, 2018.
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions.

#### 10. Test Principle
Wondfo T-Cup® Multi-Drug Urine Test Cup is a rapid test for the qualitative detection of Amphetamine, Buprenorphine, Secobarbital, Oxazepam, Cocaine, 2-ethylidene-1,5-dimethyl-3,3-
diphenylpyrrolidine,Methamphetamine, Methylenedioxymethamphetamine, Morphine, Methadone, Oxycodone, Phencyclidine, Propoxyphene, Nortriptyline and Cannabinoids in urine samples. They are lateral flow chromatographic immunoassay. When urine sample is added to the cup device, urine is absorbed into the test strip and migrates upwards by capillary action. If the concentration of target drug presented in the urine sample is below the cutoff level, the target drug will not saturate the binding sites of its specific monoclonal antibody-coated particles. The antibody-coated particles will then be captured by immobilized drug-conjugate and a visible colored band will be formed on the test line region. If the concentration of target is beyond the cutoff level, the target drug will saturate the binding sites of its specific monoclonal antibody-particles, thus the antibody-coated particles will not be captured by immobilized drug-conjugate hence no colored band will be formed on the test line region.
A band should be formed on the control line region regardless of the presence of target drug or metabolite in the sample to indicate that the tests have been performed properly.
#### 11. Performance Characteristics
- 1. Analytical Performance
- a. Precision
Precision studies were carried out for samples with concentrations of -100%cut off, -75%cut off, -50%cut off, -25%cut off, +25%cut off, +50%cut off, +75%cut off and +100%cut off. For each concentration, tests were performed two runs per day for 25 days. The results obtained are summarized in the following table.
