1 A culture is a way of life of a group of people--the behaviors, beliefs, values, and symbols that they accept, generally without thinking about them, and that are passed along by communication and imitation from one generation to the next.ULTURAL ETHNOCENTRISM. 1  Ethnocentrism is the belief that one's own culture is superior to that of other cultures. 2  It is a form of reductionism that reduces the other way of life to a distorted version of one's own.
Gas Chromatography-Mass Spectrometry (GC/MS) As It Relates To Urine Drug Testing. Gas Chromatography-Mass Spectrometry (or GC/MS) is a two-step methodology used to identify different substances within a test sample. GC/MS is widely used due to its ability to perform a specific test, and is an extremely effective in identifying the presence of a specific substance within a given sample.
The chances your sample would go straight to GC/MS are slim to none. GC/MS is only used after an immunoassay test to confirm any non negatives or to test a B sample of a split sample. If you pass a home test chances are in the high 90's that you would pass a lab test either immunoassay or GC/MS. The GC/MS is not more sensitive - its just more accurate than the Immunoassay screen. Even though their cutoff levels are different, a 50 ng Immunoassay is equivalent to the 15 ng GC/MS. The difference is that the assay looks at all 31 metabolite concentrations, while the GC/MS looks at one metabolite concentration (THC-COOH). If you were to fail the GC/MS, you wouldve failed the Immunoassay as well.
