Intended Use
Wondfo Cocaine Urine Test and Wondfo Methamphetamine Urine Test are intended for the qualitative determination of Benzoylecgonine, D(+)-Methamphetamine (target analyte) at the specific cut-off concentration in human urine. They are intended for healthcare professional use and over the counter use. Wondfo Cocaine Urine Test is an immunochromatographic assay for the qualitative determination of Benzoylecgonine in human urine at a cutoff concentration of 300ng/mL. The test is available in a dip card format and a cup format. It is intended for prescription use and over the counter use. Wondfo Methamphetamine Urine Test is an immunochromatographic assay for the qualitative determination of D(+)-Methamphetamine in human urine at a cutoff concentration of 1000 ng/mL. The test is available in a dip card format and a cup format. It is intended for prescription use and over the counter use.
Device Description
Immunochromatograph assay for Cocaine and Methamphetamine Urine Test using a lateral flow, one step system for the qualitative detection of Benzoylecgonine, D(+)-Methamphetamine (target analyte) in human urine. Each assay uses a monoclonal antibody-dye conjugate from mouse against drug with gold chloride and fixed drug-protein conjugate and anti-mouse IgG polyclonal antibody in membrane.
More Information

Not Found

No
The description details a standard immunochromatographic assay (lateral flow test) which relies on chemical reactions and antibody binding for detection, not AI/ML. There is no mention of AI, ML, or any computational analysis of results beyond a qualitative determination.

No
This device is a diagnostic test for detecting substances (cocaine and methamphetamine) in urine, not a device used to treat or cure a disease or condition.

Yes

The device is intended for the qualitative determination of specific substances (Benzoylecgonine and D(+)-Methamphetamine) in human urine, which is a method of identifying or evaluating a condition, consistent with a diagnostic device.

No

The device description clearly states it is an "Immunochromatograph assay" using a "lateral flow, one step system" with "monoclonal antibody-dye conjugate" and "fixed drug-protein conjugate and anti-mouse IgG polyclonal antibody in membrane." This describes a physical, hardware-based test kit, not a software-only device.

Based on the provided text, the device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states the tests are for the "qualitative determination of Benzoylecgonine, D(+)-Methamphetamine (target analyte) at the specific cut-off concentration in human urine." This involves testing a sample taken from the human body (urine) in vitro (outside the body) to provide diagnostic information (presence or absence of the drug above a certain level).
  • Device Description: The description details an "Immunochromatograph assay" which is a common type of in vitro diagnostic test. It describes the components used to analyze the urine sample.
  • Target Analyte: The tests are designed to detect specific substances (Benzoylecgonine and D(+)-Methamphetamine) within the urine sample.
  • Healthcare Professional and Over-the-Counter Use: While over-the-counter use is mentioned, the core function is still an in vitro diagnostic test. Many IVDs are available for over-the-counter use.

The key characteristics of an IVD are present: testing a sample from the human body outside the body to provide information about a person's health or condition.

§ 862.3250 Cocaine and cocaine metabolite test system.

(a)
Identification. A cocaine and cocaine metabolite test system is a device intended to measure cocaine and a cocaine metabolite (benzoylecgonine) in serum, plasma, and urine. Measurements obtained by this device are used in the diagnosis and treatment of cocaine use or overdose.(b)
Classification. Class II (special controls). A cocaine and cocaine metabolite 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).

Device Name: Wondfo Cocaine Urine Test

Indications for Use:

Wondfo Cocaine Urine Test is an immunochromatographic assay for the qualitative determination of Benzoylecgonine in human urine at a cutoff concentration of 300ng/mL. The test is available in a dip card format and a cup format. It is intended for prescription use and over the counter use.

The test provides only preliminary test results. A more specific alternative chemical method must be used in order to obtain a conformed analytical result. GC/MS is the preferred confirmatory method. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive.
