The primary purpose of pre-employment drug screening is to identify the presence of illicit substances or unauthorized medications in a job applicant’s system. These tests typically analyze urine, hair follicles, blood, or saliva for specific drugs and their metabolites. The analytical methods employed are designed to detect chemical compounds related to drug use, not hormonal markers associated with gestation.
The practice of pre-employment drug testing is rooted in workplace safety and productivity concerns. Employers aim to minimize risks associated with impaired performance and reduce potential liabilities. Historically, the implementation of such testing programs has evolved alongside advancements in drug detection technology and legal frameworks governing employment practices. The focus is on assessing current drug use status and not on identifying protected characteristics such as pregnancy.
