Just a quick post to let you know that we have more sensitive Cannabis urine THC drug testing strips in stock now that detect just 25g of THC compared with the standard test kits kits that detect 50g.
The lower sensitivity allows the test to detect smaller or lower levels of THC in the urine and extends the window after use of cannabis that a urine test will show its use.
For years the urine cut off levels have been set at 50g, and while this level is proven not to show after passive inhalation, the new lower test will be of interest to users wishing to screen for all exposure to the drug, not just direct use.
The procedure for running test is identical as the format of the strip tests has not changed. Simple dip one of the strips into a freshly collected urine sample and read the result at 5 minutes. A positive result indicates Cannabis + cannabis metabolites are in the sample at concentrations of 25g or above.
