Urine Point of Care
Due to being a truly independent company we are able to offer the broadest range of products available to compliment a robust and legally defensible Drug and Alcohol Policy. We listen to your needs, aims and objectives and then recommend the most effective way forward to fit in with your budget. We supply a ranges of immunoassay screening devices (urine testing strips etc) right up to more complex Point of Care / Instant screening solutions (Integrated urine test cups).

ScreenSafe UK’s Integrated Multi-Drug Screen Device is a rapid, one-step screening analysis for the simultaneous, qualitative detection of multiple drugs and drug metabolites in human urine. Its progressive design eliminates contact with urine and automatically allows the correct amount of urine onto the test strips for optimum efficiency.

The Integrated Multi-Drug Screen Device can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of specific drugs in urine.

The analysis is an immunoassay based on the principle of competitive binding. Drugs, which may be present in the urine specimen, compete against their respective drug conjugate for binding sites on their specific antibody. During testing, a urine specimen migrates upward by capillary action. A drug, if present in the urine specimen below its cut-off concentration, will not saturate the binding sites of its specific antibody. The antibody will then react with the drug-protein conjugate and a visible coloured line will show up in the test line region of the specific drug strip. The presence of drug above the cut-off concentration will saturate all the binding sites of the antibody. Therefore, the coloured line will not form in the test line region. A drug-positive urine specimen will not generate a coloured line in the specific test line region of the strip because of drug competition, while a drug-negative urine specimen will generate a line in the test line region because of the absence of drug competition. To serve as a procedural control, a coloured line will always appear at the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred. A temperature control strip is positioned on the outside of the device.

The onsite Point of Care Urine kit will enable you to screen for the following drug groups (see table below) with an instant result. This kit is a guide to any drugs that may be present in the donor and is 98.6% accurate to laboratory screening (it should be noted that initial laboratory screening is not 100% accurate). If a Positive result is shown on the test, the sample is then decanted immediately and easily into laboratory test tube travel kits, A & B sample, to be sent to the laboratory for GCMS confirmation. Results will then be sent to you within 5 working days from receipt at the laboratory.  Alcohol is not screened using this kit so a breathalyser would need to be used as an indication of alcohol use and the results then confirmed in the laboratory. Using an instant Point of Care device can show considerable cost savings in terms of testing costs and “downtime” waiting for initial screen results. Our kits are extensively used throughout the world by leading companies and organisations (including Police Forces) to fulfil their D&A urine screening requirements. Technical data is available on request.

We would recommend that all “positives” at P.O.C. screen stage are sent for confirmation analysis using our UKAS accredited laboratory service.
