How are results read?


A “Point of Care” drug test device/kit will usually include a built-in control line for each test strip to indicate that the test has performed correctly. The control line should always appear regardless of the presence of drugs. It confirms sufficient sample volume, adequate membrane wicking and correct procedural technique. If the control line does not appear, then the test is usually classed as “invalid”. A negative or “POC positive” screen result is usually read via the presence or absence of a line in the test area of the strip. All ITS urine drug testing and oral fluid drug testing products come with clear instructions on how to interpret results. Our short procedure videos also provides a helpful guide.
