Test adrenal fxn.: This test is to check on whether or not your adrenal glands are working right. The acth action is to increase production and release of corticosteroids. In the test, a small amount of synthetic acth is injected and the amount of cortisol the adrenals produce in response is measured. This is used to check for things like primary and secondary adrenal insufficiency, and addison's disease. ...Read more
Atomoxetine inhibits serotonin transporter, dopamine transporter and naroephinephrine. What does inhibit mean?
Strattera (atomoxetine): Inhibition is the opposite of stimulation, so the effectiveness is reduced. ...Read more
14/male results/ catecholamine norm?
Norepinephrine, supine 136.0 pg/ml
* epinephrine, <10 pg/ml
*dopamine, <10 pg/ml
norepinephrine, stand 457.0 pg/ml
epinephrine, 14.0 pg/ml
dopamine, 16.0 pg/m
Conc. electrolytes.: These refer to the concentration of electrolytes in the body/plasma, or the electrolyte-water balance. These measure the same thing, only that osmolality is the number of osmoles per kilogram of solvent or osm/kg, while osmolarity is the number of osmoles per liter of solution or osm/ltr. Osmolality excludes the solute, while osmolarity includes it, so osmolality has a slightly higher reading. ...Read moreSee 1 more doctor answer
Interesting question: I have not found any publications specifically studying this question. Antipsychotics and Prozac (fluoxetine) can affect prolactin, potentially changing sex hormone levels. This may or may not relate to shbg levels, though. I did find one small (20 patients) study online concerning low testosterone levels and antidepressant-induced sexual dysfunction: http://tinyurl.Com/mk84cfr further research needed. ...Read more
Metanephrine: You should discontinue Epinephrine and epinephrine-like drugs for at least 1 week before the test, stop using Acetaminophen 48 hours beforehand, and fast for 8-10 hours prior to collection. It is especially important not to have any caffeine containing food (soda, chocolate), coffee (including decaf), tobacco (smoking cigarettes or cigars), tea, or alcohol for at least 4 hours before specimen coll. ...Read moreSee 1 more doctor answer
Inject syn. ACTH: Hi. It's a test for primary adrenal insufficiency (where the adrenal glands themselves have failed) where synthetic ACTH(1-24), the N-terminal 24 amino acid peptide of native ACTH, is injected IV, and the adrenal response in making cortisol is measured at 0, 30, and 60 minutes. Dead adrenals don't respond. The ACTH-stim test does not reliably test for pituitary disease. ...Read more
Pituitary hormone: Hi. ACTH is a hormone from the pituitary gland that travels by the bloodstream to the adrenal glands and stimulates cortisol production (and to a lesser extent, aldosterone). The cortisol feeds back to the pituitary to regulate ACTH release (also effects on hypothalamic CRH, but we'll keep it simple). ACTH positive feedforward & cortisol negative feedback works beautifully. Diseases can affect it. ...Read more
No: At this time, there is no evidence to suggest this. As one may imagine, few if any studies have been performed in humans to look for this. ...Read more
Sine seratonin depletes other nerotransmitters like dopamine, norepinephrine, and epinephrine...By "deplete" does it mean a permanent thing?
Not correct: Serotonin does not deplete other neurotransmitters, but there is a balance especially between Dopamine and serotonin. This balance is dynamic and constantly re-establishing itself. Unless there is damage to neurons (which there can be when abusing certain drugs) neurotransmitter changes would not be permanent. ...Read more
Blood work showed supine norepinephrine 183pg/ml, epinephrine 11, dopac 1204, dopa 2339; standing norep 639, epi 121, dopac 1099, dopa 1992, normal?
Can taking bovine colostrum increase plasma immunoglobulin levels, thereby masking an underlying immunoglobulin deficiency by altering blood tests?
Unlikely: Very thoughtful idea. Unfortunately, the bovine immunoglobins are too large to be absorbed from the intestine and would be digested by stomach and intestinal juices and enzymes. With use you would be providing body with raw materials for making your own immunoglobulins, but at a cost. Any "complete" proteins from eggs or milk could provide the same protein precursors and support good health. ...Read moreSee 1 more doctor answer
What could cause/explain significantly (4.5x norm rang)elevated plasma norepinephrine levels in blood test , but normal urinary norepinephrine levels?
Testosterone aldo: When testosterone is given as a supplement in men with "low T", fluid retention is often noted as a side effect. The cause of this fluid retention is complex, and not just related to aldosterone levels. In a normal male with normal testosterone, this is not really a factor. ...Read more
Just one type: "selective" in this case refers to the fact that the previous generation of antidepressants, the tricyclics, worked on all 3 of the neurotransmitters in the brain thought to be involved in depression in varying degrees; serotonin, norepinephrine, and dopamine. Prozac, (fluoxetine) and the other ssris act almost entirely on serotonin. ...Read more
