Drug Testing

Drug testing always begins with one question: what do you need to establish?

If you are looking for a snapshot, to see if drugs have been used in the days prior to testing, then a simple urine or oral fluid test will suffice. Traces of drugs will remain in oral fluid for up to 48 hours, and in urine for up to 5 days.

However, if you are exploring a longer-term pattern, hair testing is essential. A 3cm strand of hair will provide a detailed record, dating back around 3 months prior to testing.  It will also highlight a number of specific drugs – providing a level of detail that could be essential in a legal suit.

Our standard Nine Panel test is designed to highlight the most common drugs.  View more details here.  Testing can also be undertaken for "legal highs", steroids and other prescribed/illicit drugs outside our standard Nine Panel test.

At Atkinson Lewis we combine the laboratory results with a Medical Interpretation in order to provide a more accurate picture of potential drug intake.  Of course in order to diagnose any psychological illness associated with drug misuse a clinical assessment would be required.
