Oral Fluid Screen & Confirmation Drug Test

The Oral Fluid Laboratory Screen & Confirmation Test confirms the presence of drugs of abuse using UKAS 17025 accredited laboratory immunoassay screening and GCMS confirmation testing methods.

This test option is an effective and accredited method of determining recent drug use with initial screening results being available within 2 working days of sample collection. If required, confirmation testing of non-negative screen results are available within a further 3 to 5 working days.

The Standard panel of 5 drug groups is listed below:

  • Amphetamines, including Methamphetamine and Ecstasy (MDMA)
  • Benzodiazepine (including Diazepam and Temazepam)
  • Cannabis
  • Cocaine
  • Opiates

The Laboratory test can be combined with a Breath Alcohol Screen to meet your testing requirements.

Each donor is legally identified at the appointment, oral fluid samples are then collected, sealed and bar coded to strict Chain of Custody Protocols. Samples are then processed to our UKAS 17025 and ILAC accredited laboratory, where initial screening test is performed.

The analysis is performed against predefined cut-off levels for all drugs tested. The link to the table below details this information, and will assist you in choosing the correct test for your circumstances.

The test is performed under strict chain of custody protocols, by fully trained and certified sample collection officers. The test is available at selected Crystal Health clinics or via the mobile collection service.

Laboratory reports are generated and issued for all samples that screen negative. Initial screening takes up to 2 working days from the appointment, however, reports are usually available the day following sample collection.

Samples that screen non-negative are issued with a ‘Undergoing Further Analysis’ report and require additional Confirmation Testing. Confirmation Testing is required to identify the drug or metabolite found in the sample and the quantity present.

Any sample which contains the presence of a drug or metabolite over the cut-off level, will be issued a positive laboratory report, providing evidence of drug abuse. Dependant on the circumstances, the laboratory report may specify whether the drug and its quantity can be deemed therapeutic i.e. in line with declared medication. Further investigation to confirm this can be undertaken by utilising the Crystal Healths Medical Review Service.

All administration including the test results process is performed in compliance with ISO 9001, ISO 27001 and ISO 14001. All laboratory reports are provided in secure PDF format via email and/or hard copy.

*Confirmation testing may take upto a further 5 working days. Additional charges may apply for confirmation testing per donor depending on your requirements.
