No
The device description details a standard immunochromatographic assay (lateral flow test) which relies on chemical reactions and antibody binding, not AI/ML. There are no mentions of AI, ML, image processing, or data sets typically associated with AI/ML devices.
No
The device is described as an immunochromatographic assay for the qualitative determination of Cannabinoids in human urine, which is a diagnostic (detection) purpose, not a therapeutic (treatment) purpose.
Yes
The device is intended for the qualitative determination of Cannabinoids in human urine, which provides preliminary test results. This function of identifying specific substances in a biological sample to indicate a condition (presence of Cannabinoids) falls within the definition of a diagnostic device, even though confirmatory tests are required.
No
The device description clearly states it is an "Immunochromatographic assay" using a "lateral flow system" and includes physical components like "monoclonal antibody-dye congugate," "gold chloride," and "membrane." This indicates 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 Cannabinoids in human urine." This involves testing a sample taken from the human body (urine) outside the body (in vitro) to gain information about a physiological state (presence of cannabinoids).
- Device Description: The description details an "Immunochromatographic assay for Cannabinoids urine test." This is a common type of in vitro diagnostic test.
- Anatomical Site: The anatomical site is "human urine," which is a biological sample tested in vitro.
The definition of an IVD generally includes devices intended for use in the collection, preparation, and examination of specimens taken from the human body for the purpose of providing information for the diagnosis, treatment, or prevention of disease or for the determination of the state of health. This device fits that description by providing information about the presence of cannabinoids in a human sample.

Intended Use / Indications for Use
The Cannabinoids Urine Test is intended for the qualitative determination of Cannabinoids in human i he Cannabilioius Unite Test is intended for the qualities and over the counter use.
Wondfo Cannabinoids Urine Test is an immunochromatographic assay for the qualitative determination of Cannabinoids in human urine. The test is available in a cassette format. The test has a cutoff of 50ng/mL of Cannabinoids. It is intended for prescription use and over the counter use.
The test provides only preliminary test results. A more specific alternative chemical must be used in order to obtain a conformed analytical result. GCMS 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.

§ 862.3870 Cannabinoid test system.
(a)
Identification. A cannabinoid test system is a device intended to measure any of the cannabinoids, hallucinogenic compounds endogenous to marihuana, in serum, plasma, saliva, and urine. Cannabinoid compounds includedelta -9-tetrahydrocannabinol, cannabidiol, cannabinol, and cannabichromene. Measurements obtained by this device are used in the diagnosis and treatment of cannabinoid use or abuse and in monitoring levels of cannabinoids during clinical investigational use.(b)
Classification. Class II (special controls). A cannabinoid 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).
