Medscreen’s legally defensible urine analysis is carried out to accepted international standards. Our laboratory is UKAS Accredited to ISO 17025.

Medscreen’s collection procedures and specimen collection kits are an integral part of the ‘Chain of Custody’ for each specimen.

A sample will only be reported ‘positive’ by the laboratory after it has undergone two separate analyses. The first (screening) is by immunoassay which rapidly identifies negative samples ensuring a fast reporting time for the majority of results.

Samples that screen positive will then be tested by GC or LC/MS (Gas or Liquid Chromatography / Mass Spectrometry), which can identify with precision the drugs present in the urine. The result may indicate that medication is a possible cause of the positive result.
