A document that outlines the findings of a toxicology analysis performed on a biological specimen, such as urine, blood, or hair, constitutes the official record of a drug screen. This record details the substances tested for, the cutoff levels used to determine a positive result, and the ultimate determination of whether the sample contained detectable levels of illicit or prescription drugs beyond the accepted limits. For example, such a document might indicate the presence or absence of specific substances like amphetamines, opioids, or cannabinoids, along with their respective concentrations and the laboratory’s conclusive statement.
These records are critical in various settings, including employment, healthcare, and legal contexts. Employers often utilize them to ensure workplace safety and compliance with company policies. Healthcare providers rely on them to monitor patient medication adherence and identify potential substance abuse issues. Legal authorities may use them as evidence in criminal investigations or child custody disputes. The historical evolution of these documents reflects advancements in drug testing technology, standardization of reporting practices, and increasing emphasis on accuracy and chain of custody procedures.
