Part Descriptions

LP15900-1   Thyroxine
The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosine (monoiodotyrosine) and the coupling of iodotyrosine (diiodotyrosine) in thyroglobulin. Thyroxine is separated from thyroglobulin by proteolysis and released in the blood. Thyroxine is peripherally deiodinated to form triiodothyronine which exerts broad stimulatory effects on cell metabolism. Source: National Library of Medicine, MeSH 2006

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.[PMID: 17268583] Source: Regenstrief LOINC
