Workplace Urine Testing

Urine Testing · Urine Testing overview

Workplace urine testing in the occupational hygiene sense is exposure biomonitoring — measuring a substance or its metabolite in worker urine to verify control adequacy. It is not drugs-of-abuse testing and not a medical investigation.

Scope and intent

Workplace urine testing for exposure purposes is governed by HSE biological monitoring guidance and run under occupational health confidentiality. Individual results are not employment decisions; they are control-adequacy data. This distinguishes it sharply from drugs-of-abuse screening, which has separate ethical and legal frameworks.

Collection logistics

On-site collection rooms with privacy, observed only where required by the substance protocol, 60 ml universal containers, chain of custody from collection to laboratory. Trained collection staff record last-exposure time and shift information against each sample.

Ethical handling

Workers must be informed of the substance and biomarker, the purpose, who sees results and how long results are retained. Individual results are confidential occupational health data; the employer receives only de-identified group statistics.
