The rapid test strip for urine screening with a sensitivity of 50ng works by detecting the presence of specific drugs or their metabolites in the urine sample. The test strip contains antibodies or antigens that are specific to the drug being tested for. When the urine sample is applied to the test strip, any drug or metabolite present will bind to the antibodies or antigens, causing a visible reaction on the test strip. The sensitivity of 50ng means that the test can detect the presence of the drug or metabolite at a concentration as low as 50 nanograms per milliliter of urine. If the concentration of the drug or metabolite in the urine sample is above this threshold, the test will produce a positive result. **
