ntroducing a Drug and Alcohol policy into any workplace is complex and can cause confusion and unwanted consequences. Screen4 work closely with our customers to ensure any proposals put towards employees are appropriate and robust solutions. WHY TEST?

Drug Testing

A needle over some pills.

Screen4 offer a number of Drug Testing methods. These include both instant on site tests and Chain of Custody samples analysed at UKAS accredited Laboratories.

Point of Care Testing

Screen4 provide Point of Care testing products for urine and oral fluid that are fully CE compliant and manufactured under ISO 13485 guidelines; these are accurate and prove to have time and cost savings in comparison to Laboratory Screening. Where required positive results can be backed up by a Chain of Custody sample sent for Laboratory Confirmation.

Laboratory Services

Screen4 is able to provide UKAS accredited fully validated Chain of Custody Laboratory testing of urine and oral fluid. There are two types of Laboratory test available; a laboratory 'screening' and a laboratory 'confirmation' test.

Screening Test

Immunoassay screening is not a conclusive test but gives an indication as to whether a test sample is positive or negative for the drug group being analysed. It can not take into account any legitimate medication taken which lies in the same group as any illegal substance.

Confirmation Test

A confirmation test validates immunoassay screening results since it provides drug analysis of higher specificity. The most commonly recommended forms of confirmation test are Gas Chromatography - Mass Spectrometry (GC/MS) and Liquid Chromatography - Mass Spectrometry (LC-MS).

Urine Testing

Urine Testing is the historical, tried and tested method of detecting drugs of abuse and alcohol. The advantages are:

  • When compared to Oral Fluid the detection window for some drugs within Urine is increased
  • The results of the test may be displayed within minutes
  • The availability of a split sample for confirmation analysis at the Laboratory
  • Sample taken under Chain of Custody conditions, fully legally defensible
  • Urine Allows for simultaneous detection of up to ten different drug groups from a single sample

Oral Fluid Testing

The advantages of using Oral Fluid Testing are:

  • Simple, painless, less invasive sample collection
  • Sample adulteration is prevented because the collection is directly observed
  • No requirement for special testing facilities
  • The results of the test may be displayed within minutes
  • Sample taken under Chain of Custody conditions, fully legally defensible
  • Oral Fluid allows for simultaneous detection of up to ten different drug groups from a single sample

Hair Testing

Hair testing shows up substance abuse over a much longer period than oral fluid or urine.  The main benefits of hair testing are:

  • Longer window of detection dependent on hair length.
  • Detailed data can be provided on a month by month basis.
  • no requirement for special testing facilities
  • Sample taken under Chain of Custody conditions, fully legally defensible
