2238-4Estradiol (E2) [Mass/volume] in Saliva (oral fluid)Active

Part Descriptions

LP14497-9   Estradiol
Estradiol, derived from the ovary, testis, and placenta, may be the most biologically active estrogen. It is measured in the serum to evaluate hypogonadotropic and hypoestrogenic causes of menstrual abnormalities, sexual immaturity in females, estrogen-producing tumors, and feminization in males. Estrogens are increased in liver cirrhosis and depressed in Turner's syndrome. Ingestion of estrogens, such as oral contraceptives, increases the serum levels. 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.
