What is a lateral flow “Point of Care” drug test device/kit?


A lateral flow “Point of Care” drug test device/kit is a competitive binding, lateral flow immunochromatographic assay for qualitative and simultaneous detection of drugs of abuse in human urine or oral fluid specimens. The test devices/kits usually consist of one or more membrane strips mounted in a plastic cassette/device. A bit like a pregnancy test – they give an indication via a marker which is interpreted as either a “Negative” or “Positive” screen result. This initial “screen” result is never 100% accurate and requires further (more expensive) confirmation analysis. This result can only be quantified via laboratory confirmatory analysis. ITS would recommend that this was carried out via a UKAS accredited laboratory.
