Here's a detailed product description for THC DOA Rapid Tests, formatted in Markdown:
The THC DOA Rapid Test Strip provides a quick and highly reliable method for the qualitative detection of 11-nor-Δ9-THC-9-COOH (a major metabolite of marijuana) in human urine. Designed for ease of use and rapid results, these tests are an essential tool for preliminary drug screening in various professional and personal settings.
The THC DOA Rapid Test Strip utilizes an immunochromatographic assay. When the absorbent tip of the strip is immersed in a urine sample, the sample is absorbed by capillary action. If THC metabolites are present in the urine above the 50 ng/mL cutoff, they will compete with the drug conjugates in the test strip for binding sites on the antibodies. This competitive reaction leads to the appearance or absence of a colored line in the test region (T). A colored line always appears in the control region (C), indicating proper test function.
