Company Profile

• Aviation and Workplace Drug Testing Solutions - Safety Sensitive Roles

  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
  

• Aviation and Workplace Alcohol Testing Solutions - Safety Sensitive Roles

  Screen4 offers a number of alcohol testing products ranging from legally defensible calibrated breathalysers to more cost effective disposable tests.

  Alcohol is absorbed into the blood stream within a few minutes of consumption. It has an initial stimulant effect, acts as a depressant, dehydrates the body tissues and even at levels below the legal drink and drive limits will affect co-ordination, reaction times, thinking, judgement and mood.

  The easiest way of detecting levels of Alcohol in a person is by taking a breath sample. This is a straight forward process which is not intrusive. Using a calibrated instrument, the result may be used as evidence.

  The benefits of breath testing for alcohol are:

  • An evidential print out is instantly obtained for each test
  • The results gained are fully legally defensible
  • Quick, easy non intrusive
  • A calibrated instrument is used
