Yes. The use of saliva as a specimen matrix for drugs of abuse screening has been cited in the literature for many years.
Daewoo Precision Industries K2
Daewoo Precision Industries K2 assault rifle was developed by the Agency for Defense Development and manufactured by Daewoo Precision Industries. It is currently used as the standard service rifle of the Republic of Korea Armed Forces. Shoulder-fired and gas-operated containing long-stroke piston, the K2 is capable of firing both 5.56x45mm NATO and .223 Remington ammunitions, but use of .223 Remington will fail to achieve its full potential, decreasing its accuracy and effective range slightly. The K2 supplanted the M16A1 assault rifle for the Republic of Korea Armed Forces since its adoption in 1984.
Saliva testing is a diagnostic technique that involves laboratory analysis of saliva to identify markers of endocrine, immunologic, inflammatory, infectious, and other types of conditions. Saliva is a useful biological fluid for assaying steroid hormones such as cortisol, genetic material like RNA, proteins such as enzymes and antibodies, and a variety of other substances, including natural metabolites, including saliva nitrite, a biomarker for nitric oxide status (see below for Cardiovascular Disease, Nitric Oxide: a salivary biomarker for cardio-protection). Saliva testing is used to screen for or diagnose numerous conditions and disease states, including Cushing's disease, anovulation, HIV, cancer, parasites, hypogonadism, and allergies. Salivary testing has even been used by the U.S. government to assess circadian rhythm shifts in astronauts before flight and to evaluate hormonal profiles of soldiers undergoing military survival training.
Proponents of saliva testing cite its ease of collection, safety, non-invasiveness, affordability, accuracy, and capacity to circumvent venipuncture as the primary advantages when compared to blood testing and other types of diagnostic testing. Additionally, since multiple samples can be readily obtained, saliva testing is particularly useful for performing chronobiological assessments that span hours, days, or weeks.
A drug test is a technical analysis of a biological specimen – for example urine, hair, blood, breath air, sweat, or oral fluid / saliva – to determine the presence or absence of specified parent drugs or their metabolites. Major uses of drug testing are to detect the presence of performance enhancing steroids in sport or for drugs prohibited by laws, such as cannabis, cocaine and heroin.
A "10-panel urine screen" consists of 10 of the following:
Body fluid, bodily fluids, or biofluids are liquids originating from inside the bodies of living people. They include fluids that are excreted or secreted from the body as well as body water that normally is not.
The dominating content of body fluids is body water. Approximately 60-65% of body water is contained within the cells (in intracellular fluid) with the other 35-40% of body water contained outside the cells (in extracellular fluid). This fluid component outside of the cells includes the fluid between the cells (interstitial fluid), lymph and blood. There are approximately 6 to 10 liters of lymph in the body, compared to 3.5 to 5 liters of blood.
A medical test is a kind of medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, and determine a course of treatment.
Medical tests can be classified by what the test result will be used for, mainly including usage for diagnosis, screening or evaluation, as separately detailed below.
