Laboratory Services - Screen4

Laboratory Services

Lab ServicesScreen4 is able to provide UKAS accredited fully validated Chain of Custody Laboratory testing of urine, oral fluid and hair. 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 cannot 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).

We can also provide additional laboratory services including steroid testing, blood borne virus (BBV) testing and benzene bio-monitoring.
