For Cause Drug and Alcohol Service


Optima Health provides access to a For Cause Drug and Alcohol Collection Service via our partners, Alere Toxicology.

Authorised users can access the service 24 hours a day, 7 days a week via the Optima Health Helpdesk on 0845 608 0656, selecting Option 2.

A collection officer will attend the location within two hours, take the samples then send them by courier directly to a laboratory for immediate analysis whatever time of the day or night, 365 days per year.

Activating a call out:

Upon dialling our emergency hotline, you will need to provide the following information:

  • Your company name and PIN (1925)
  • Level of service required (i.e. high priority or whistleblower)
  • Your name and contact information. We may need to contact you within the two hours following activation. Therefore, a direct mobile number is preferred.
  • Cost centre number
  • Area and route
  • Address and directions to the location
  • This reporting point must be a safe and clearly identifiable venue (e.g. Gatehouse, Reception). The collecting officer must be escorted from this point onwards. We are not able to attend uncontrolled environments (e.g. donors’ homes).
  • Site contact name and number. The collecting officer will ask for this person upon arrival. This person will need to be available for the entire duration that our collecting officer is on site.
  • The category of incident (i.e. impairment, suspicion or post incident)
  • The number of people to be tested and whether they are Network Rail employees or contractors.

Once this information has been confirmed the call out is activated, the clock is started and a collecting officer will be dispatched. The collecting officer will telephone you to confirm that they are on the way and we will keep you informed of any developments.


  • Breath alcohol results will be available immediately on site
  • Urine samples will be collected by a same-day courier and taken directly to our laboratory
  • High priority interim result available within 24 hours of the call out
  • Confirmed result uploaded directly on to Sentinel
