Oral drug tests are usually conducted for the purposes of detecting whether or not eth individual has recently partaken in any drugs. They are conducted widely but they are mostly used in people that have recently partaken of drugs. They have also been known to produce very accurate results. All of the various types of standardized oral drug testing are normally conducted to test for a certain group of drugs identified as SAMHSA-5.
The SAMHSA group of drugs includes phencyclidine, abbreviated as PCP, opiates, cocaine, marijuana and amphetamines. Expanded drug tests will normally also include testing for benzodiazepines including Xanax and valium, methadone, ecstasy and alcohol.
The oral swab drug test, also referred to as the saliva test or oral fluid tests is a one of the oral drug testing types and it is very frequently used due to its invasive nature and provision of a clean sample. With this type of test, the saliva is mostly tested to detect whether there are any drug metabolites or drugs.
Drug metabolites are simply by-products of the drugs that usually remain in the body for quite some amount of time even after the effects of the drugs have already cleared. The detection period of these types of tests is however a bit low and they work well to detect current intoxication and recent use of drugs. Research is actually showing that drugs only stay in saliva for between 12 and 24 hours.
The cost of saliva testing has been said to be higher compared to that of the urine test but they tend to be cheaper than the blood test r the hair test. People prefer it though to its ease of conducting and its less invasive nature. With the urine test, it is very easy for an individual to switch the sample with that of another person thus the accuracy of the test is always thrown into question.
