THC Rapid Test colloidal gold rapid test kit is specifically designed for urine samples and can qualitatively detect tetrahydrocannabinol acid (THC-COOH) in human urine, with a detection threshold accurately set at 50 ng/mL. The product does not require specialized laboratory equipment; the test can be completed in three simple steps, with easy operation and no professional training needed. The kit is suitable for various scenarios, including workplace pre-employment screening, community drug rehabilitation monitoring, or regular testing of personnel in high-risk industries. It can be stored in a sealed, dry environment at 2–30°C, with a long shelf life of up to 12 months, and can be used immediately after opening without affecting accuracy. Validated with 150 negative urine samples, it has a 100% compliance rate and shows no cross-reactivity with common substances such as acetaminophen or caffeine, effectively avoiding false-positive interference.

Q: What's the detection accuracy?
A: Sensitivity up to 50ng/ml (common cutoff value), accuracy ≥95%, results for preliminary screening only.
Q: Who is it suitable for?
A: Personal self-testing, workplace screening, drug rehabilitation institution monitoring, etc.
Q: Does positive mean definite marijuana use?
A: Possibly, but false positives may occur if taking hemp-containing drugs (e.g., some health products) recently; lab re-test is recommended.
