The sample is then tested using a variety of methods, such as enzyme- linked immunosorbent assay (ELISA), gas chromatography-mass spectrometry (GC-MS), or high-performance liquid chromatography (HPLC).
Saliva drug testing can be used to detect a variety of drugs, including marijuana, cocaine, opioids, amphetamines, and benzodiazepines. The detection window for saliva drug testing varies depending on the drug being tested for and the frequency of drug use, but typically ranges from a few hours to a few days.
Advantage of Saliva Testing
Saliva drug testing has several
advantages over other types of
drug testing methods, such as
urine or blood testing. Saliva
testing is less invasive than blood
testing and can be performed on-
site, making it a useful tool for
workplace drug testing or
roadside drug testing. Additionally, saliva drug testing can detect recent drug use, as drugs and their metabolites can be detected in saliva within minutes of use.
However, there are some limitations to saliva drug testing. The detection window for some drugs may be shorter in saliva than in blood or urine, which can lead to false-negative results. Additionally, the accuracy of saliva drug testing can be affected by factors such as the collection method and the presence of food or drink in the mouth.
