Which option is listed as an alcohol or drug testing option besides blood, breath, and urine?

• A. Hair sample
• B. Other bodily substance
• C. Saliva
• D. Sweat

Answer: (C)

Testing with alcohol or drugs can use several matrices beyond blood, breath, and urine. Saliva, or oral fluid, is a commonly used option because collection is simple, noninvasive, and can be done quickly on-site. It tends to reflect recent drug use and, for alcohol, can correlate with blood alcohol levels in many settings, making it practical for timely screening. Hair samples, in contrast, show longer-term history—weeks to months of use—so they’re useful for chronic patterns rather than immediate impairment. Sweat testing uses patches that monitor exposure over a longer period, which is helpful for continuous monitoring but not as a rapid one-time screen. Because of its ease of collection and relevance to recent use, saliva stands out as a readily available alternative beyond the traditional three.
