- Comment
- The Method values "Screen" and "Confirm" reflect a regulatory testing requirement rather than an actual laboratory method. This term has been discouraged in favor of terms specifying the true method (Immunoassay or Mass Spectrometry) or a methodless term where appropriate. Please select the replacement term that matches your actual testing method.
Part Descriptions
LP16194-0 Methamphetamine
Methamphetamine (MA) is a drug of abuse also referred to as meth, crystal and speed. It is a central nervous system stimulant that can be injected, smoked, snorted or ingested. Short-term MA abuse causes an increase of energy, sense of well-being and decreased appetite that lasts 6-8 hours. PMID: 19042205 MA use can lead to stroke, cardiac arrhythmia, stomach cramps, shaking, anxiety, insomnia, paranoia, hallucinations, and structural changes to the brain. Pregnant women who use MA can cause growth retardation, premature birth, and developmental disorders in neonates and long lasting intellectual deficits to the children as they grow. PMID: 10908000 Users addicted to MA experience withdrawal symptoms that include dysphoria, fatigue, insomnia and an increased appetite. In chronic MA users positron emission tomography has proven a decrease in dopamine D2 receptors which is associated with mental deterioration that can be reversed to some extent after abstaining from MA. PMID: 19042205

LP7565-7 Saliva
Saliva is produced primarily by the parotid, submaxillary, and sublingual glands. It is secreted at the rate of 0-3 milliliters per minute which is affected by various factors including anxiety, hydration and hunger. Oral fluid is broadly used to test for drugs of abuse in employment and forensic settings, and is especially useful since it is difficult to adulterate, is quick and is non-invasive. Oral fluid is used to test a variety of analytes, including to test alcohol, HIV and other antibodies, therapeutic drugs and steroids, but its primary use is to test for drugs of abuse including amphetamines, cocaine and metabolites, opioids, methadone, cannabis and heroin.

LP262420-5 Saliva DRUG/TOX
Oral fluid (or saliva) is produced primarily by the parotid, submaxillary, and sublingual glands. It is secreted at the rate of 0-3 milliliters per minute which is affected by various factors including anxiety, hydration and hunger. Oral fluid is broadly used to test for drugs of abuse in employment and forensic settings, and is especially useful since it is difficult to adulterate, is quick and is non-invasive. Oral fluid is used to test a variety of analytes, including to test alcohol, HIV and other antibodies, therapeutic drugs and steroids, but its primary use is to test for drugs of abuse including amphetamines, cocaine and metabolites, opioids, methadone, cannabis and heroin. The test procedures that use oral fluid for drug screening are usually similar to those for other specimens but adapted for oral fluid. Oral fluid is broadly used to test for drugs of abuse in employment and forensic settings, and is especially useful since it is difficult to adulterate, is quick and is non-invasive. Drugs present in oral fluid are often the parent drug rather than a metabolite and tests kits reflect those differences. Concentrations of cocaine, amphetamines and some opioids in oral fluid are either similar or higher than concentrations in plasma. The concentration of tetrahydrocannabinol (THC) in oral fluid is similar to that of plasma, though in cases where recent ingestion has occurred, levels may be higher due to the significant local absorption in the oral cavity. Confirmatory testing on oral fluid using liquid chromatography-mass spectrometry (LC-MS) is highly sensitive and specific even on relatively small sample sizes. An increased understanding of pharmacokinetics in oral fluid has flourished inover the last ten years has allowed the correlation of . As a result, the concentrations of various drugs in oral fluid have been correlated to blood concentrations and the effects they have on the individual. PMID: 17268583
