It analyzes a urine sample to detect certain medical conditions and substances.
This urine test plays a critical role in ensuring public safety on roadways. By identifying potential health issues, it helps mitigate risks associated with impaired driving. Historically, the inclusion of urinalysis has evolved alongside advancements in medical understanding and a growing emphasis on preventative healthcare within the transportation industry.
