Challenge
An employee was suspended from work after a routine workplace drug test returned a positive result for opiates. They had forgotten to disclose that they had recently taken co-codamol for back pain, leading to concerns that they may have been using other substances. While awaiting the outcome of an investigation, they were unable to work, placing them under significant stress.
Solution
To clarify the situation, their employer arranged for a hair strand drug test with us. Unlike basic drug screening, which simply detects the presence of a substance, our testing provides a full analysis, including the identification of specific metabolites that distinguish between prescribed medication and illicit drug use.
Result
The results confirmed that the only opiate present was consistent with co-codamol, with no evidence of any other opiates in their system. This corroborated the employee’s explanation, providing clear scientific evidence that they had not used any unauthorised substances.
With this detailed analysis, the employer was able to confidently resolve the investigation, allowing the employee to return to work.
Our testing goes beyond a simple yes or no—we provide a full breakdown of results, quantifying each metabolite group to give a clear, accurate picture. If needed, we also provide expert reports that take medications and other contributing factors into account to ensure a fair and thorough assessment.
If you need scientifically reliable testing to support a workplace investigation, we offer fast, accurate hair strand analysis and expert reports. Our team is committed to delivering clear, court-admissible evidence for a range of legal matters.
