Part Descriptions

LP15560-3   Estrone
Estrone has low biological activity compared with estridiol. In humans the major source of E1 is the extraglandular conversion of androstenedione secreted by the adrenal gland. In women the sequence of events during the menstrual cycle depends on the stimulation of the ovary by gonadotropins and feedback by the estrogens on the hypothalamus and pituitary. Under normal circumstances the amount of E1 generated is small and does not play a significant role in feedback, but under abnormal conditions [e.g. obesity] the amount may become sufficient to interfere with normal feedback mechanisms and produce disturbances of the ovarian cycle. In men, E1 levels may be helpful in the diagnosis of gynecomastia or the detection of estrogen-producing tumors. Source: Regenstrief Institute

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.
