What is it indicated for?

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 and a strip format. The test has a cutoff of S0ng/mL of Cannabinolds. 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.

Indications for use as stated in the FDA summary.
