Saliva-based diagnostic tools designed for the detection of drug use represent a non-invasive method for substance abuse screening. These kits typically involve the collection of an oral fluid sample, which is then tested for the presence of specific drugs or their metabolites using immunoassay or chromatographic techniques. For example, a healthcare provider might use such a device to screen a patient presenting with symptoms suggestive of drug intoxication.
The utilization of these devices offers several advantages, including ease of collection and reduced risk of adulteration compared to urine-based testing. Their application spans various sectors, such as workplace drug screening, law enforcement, and clinical settings. Historically, traditional methods relied heavily on urine samples; however, the convenience and rapid results offered by oral fluid testing have contributed to its increasing adoption as a valuable screening tool.
