Saliva-based drug screening utilizes oral fluid to detect the presence of various substances. This method offers a non-invasive, observed collection process, making it a popular choice for workplace testing and roadside checks. For example, a sample might be analyzed for marijuana, cocaine, or amphetamines. The analysis typically yields either a positive, negative, or inconclusive result.
Due to the ease and speed of sample collection, oral fluid testing is often favored for its efficiency and cost-effectiveness. Its direct observation process also minimizes the potential for adulteration or substitution, enhancing the reliability of results. Historically, urinalysis has been the standard method for drug detection, however, saliva testing has gained prominence as a viable alternative in recent decades due to its advantages. This shift has been further accelerated by advancements in laboratory technology, enabling the detection of a wider range of substances with increased accuracy.
