Drug testing labs

Drug testing labs analyze biological samples like urine, blood, hair, or saliva to detect the presence of substances such as drugs or alcohol. They use precise scientific methods like chromatography and spectroscopy to identify and measure these substances accurately. These labs support law enforcement, workplaces, and healthcare providers in ensuring safety, compliance, or medical evaluation. The process involves collecting a sample, preparing it for testing, and then conducting detailed analysis in controlled lab environments, generating reliable results to determine substance use or exposure.
