12 Possible Causes for Prolactin Decreased or Not Detectable

  • Prolactinoma

    A blood test is used to detect excess prolactin. If prolactin levels are high, more tests are usually done to check blood levels of thyroid hormone.[hormone.org] Production of breast milk when not pregnant or nursing Men may also have: Erectile dysfunction—trouble getting or keeping an erection Breast enlargement, called gynecomastia Decreased[hormone.org]

  • Chest Wall Disorder

    A blood test is used to detect excess prolactin. If prolactin levels are high, more tests are usually done to check blood levels of thyroid hormone.[hormone.org] Production of breast milk when not pregnant or nursing Men may also have: Erectile dysfunction—trouble getting or keeping an erection Breast enlargement, called gynecomastia Decreased[hormone.org]

  • Growth Delay due to Insulin-Like Growth Factor I Resistance

    IGF-1 may be ordered with other pituitary hormone tests, such as prolactin or FSH and LH, to help diagnose pituitary gland dysfunction and decreased pituitary hormones ( hypopituitarism[labtestsonline.org] IGF-1 testing and a GH suppression test can be used to detect and monitor treatment of a GH-producing pituitary tumor.[labtestsonline.org]

  • Laron Syndrome

    […] was detectable.[ncbi.nlm.nih.gov] Because bGH does not bind to prolactin receptors and because excess prolactin (1 μg/ml) did not diminish binding, the finding may indicate the presence of other type(s) of[ncbi.nlm.nih.gov] As shown in Fig. 1 E, the ability of liver from GHR/BP / mice to bind bGH was greatly decreased compared with GHR/BP / littermates although a small amount of residual binding[ncbi.nlm.nih.gov]

  • Renal Amyloidosis

    […] of FT3 and testosterone, normal value of TSH, cortisol, prolactin and fasting insulin.[casesjournal.biomedcentral.com] Urine analysis detected proteinuria of 2.9 g/dL. Upper endoscopy was performed, which showed sever inflammation of post-bulbar duodenum with diffuse fibrinous erosions.[casesjournal.biomedcentral.com] Additional biochemical tests revealed CD8 deficiency and abnormal CD4/CD8 ratio, decreased concentration of IgA, IgM and IgG, elevated level of IgE, reduced concentration[casesjournal.biomedcentral.com]

  • Hyperprolactinemia

    A blood test is used to detect excess prolactin. If prolactin levels are high, more tests are usually done to check blood levels of thyroid hormone.[hormone.org] Production of breast milk when not pregnant or nursing Men may also have: Erectile dysfunction—trouble getting or keeping an erection Breast enlargement, called gynecomastia Decreased[hormone.org]

  • Primary Hypothyroidism

    Laboratory investigations revealed grossly increased thyroid stimulating hormone, decreased thyroxine, and slightly elevated prolactin levels in all cases.[ncbi.nlm.nih.gov] On MRI, pituitary mass were detected a large intrasellar with/without suprasellar extension in all patients,showing the characteristic of symmetric enlargement.[ncbi.nlm.nih.gov]

  • Bromocriptine

    Alcohol use: disulfiram-like reaction Patient monitoring • Monitor blood pressure to detect hypotension. • When giving drug for hyperprolactinemia, monitor serum prolactin[medical-dictionary.thefreedictionary.com] Chaste tree fruit: decreased bromocriptine effects Drug-behaviors.[medical-dictionary.thefreedictionary.com]

  • Aripiprazole

    The decrease in serum prolactin concentrations detected in aripiprazole treated patients in our trial has been previously reported [ 8 , 9 ], although its clinical consequences[link.springer.com] It is known that serum prolactin level decrease can be induced by the dopamine D 2 receptor partial agonism, a major property of aripiprazole [ 5 , 22 ].[link.springer.com]

  • Insulin-Like Growth Factor I

    IGF-1 may be ordered with other pituitary hormone tests, such as prolactin or FSH and LH, to help diagnose pituitary gland dysfunction and decreased pituitary hormones ( hypopituitarism[labtestsonline.org] IGF-1 testing and a GH suppression test can be used to detect and monitor treatment of a GH-producing pituitary tumor.[labtestsonline.org]
