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. These are either ‘non-negative’ or ‘negative’.
Following initial collection preparations, donors are legally identified and their samples are 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 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 of further 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).
