The morphine Test Cassette uses the technical principle of the competitive method. It can be stored at room temperature without any instrumentation and is tested on site, regardless of site or environmental restrictions. Accurate results, rapid detection, results can be interpreted in 5 minutes, saving time and the results are discernible to the naked eye. High sensitivity: the detection threshold is low, which effectively increases the detection rate of morphine abuse. Good specificity: Highly specific monoclonal antibodies are used to minimise possible cross-reactivity.
