01Hair / Long window

Hair Drug Testing

Laboratory LC-MS/MS confirmation of traditional and novel psychoactive substances (NPS) in hair. A root segment of about 3 cm can cover up to roughly a 180-day look-back window and is difficult to interrupt or substitute, suitable for pre-employment screening, periodic institutional monitoring and recovery follow-up, with markedly fewer test cycles than urine. Specific scope per RID-confirmed materials.

02Wastewater / Monitoring

Wastewater Drug Monitoring

Area-level drug monitoring through systematic sampling and analysis of municipal and campus wastewater, assessing drug use within an enclosed area or building — with broad coverage, objective data and clear trends. For example, an enterprise identified abuse signals by testing campus wastewater and initiated a targeted screening to reduce potential risk.

FAQ

Common questions

QHow long does testing take?

On-site rapid screening gives a result in about 5 minutes; for laboratory LC-MS/MS confirmation, the report is issued roughly 1–3 working days after the sample reaches the laboratory.

QHow much sample is needed, and how is it collected?

Hair: a root segment of about 3 cm, roughly 100 mg (90–120 strands). Urine: about 30 mL in a sealed container. RID provides detailed collection and shipping guidance for each test.

QWhat does the report look like?

An English-language testing report delivered electronically; stamped or paper copies can be arranged on request.

QHow is confidentiality handled?

Samples and results are handled confidentially. The website inquiry form forwards your message only and stores no submitted data. Specific terms follow RID-confirmed materials and local regulations.

QHow do we get started?

Contact us with your sample type, testing scope and report needs. RID replies with the right testing path and sample-collection guidance — then you send samples and receive the report.
