Urine Drug Screening
Urine drug screening can be administered via two methods, instant ‘point of care’ or via Laboratory analysis. The screening stage provides initial results which determine if substances are present in a person’s sample or not, either ‘non-negative’ or ‘negative’.
Following initial collection preparations, donors are legally identified and their samples collected using a strict set of procedures called ‘the chain of custody’. The sample is then either screened straight away using a point of care device or packaged with the appropriate security protocols to ensure the integrity of the sample and screened at the Laboratory. If either method presents a ‘non negative’ result, the sample enters the Confirmation stage which involves more in depth scientific analysis. At this point, it can be determined whether the substance found if medication in line with a therapeutic dose or illegal substance(s).
