Q: had catecholamine test. after injection, dopamine result was still <30. normal range if 0-48. my epinephrine was <15. normal is 0-62. meaning/cause?

Results are normal.: The catecholamines are checked to see if there is excessive production of hormones from the adrenal medulla. This may results in high blood pressure, palpitations, sweating, headaches, anxiety / panic. Your levels are normal and this is reassuring. What injection did you receive before checking for dopamine?

Q: i have been diagnosed with pots and started on nadolol. now i have to have catecholamine testing. do i have to stop the nadolol days prior to the test?

Yes: Stop at least 3 -4 days beforehand.

Q: why would a doctor order a 24 hour urine for catecholamines test?

To check high levels: Elevated catecholamines in the urine can be associated with hypertension, kidney problems or some excess secretion of catecholamines from other body tissues and creat hypertension and flushing.

Q: what are the causes of elevated catecholamines in a 24 hour urine test?

Possible: adrenal over secretion or a tumor like a pheochromocytoma would be common causes

Q: what is the correlation of cortisol and catecholamines? i need to do a 24 hr urine test and both of these are being tested. many thanks!

Adrenal: They are trying to rule out adrenal over secretion. Both hormones come out of the adrenal glands.

Question 1

22yo/ female/ history of syncope, tachycardia, nausea/ recent catecholamine plasma levels- supine nor.=582, epi.=36, dop.=37; standing nor=1167, epi=153, dop=44 what type of specialist should i look for?

Accepted Answer

Endocrinologist: Either an endocrinologist or internist would be able to further evaluate these symptoms and labs.

Question 2

what is the purpose of catecholamines tests?

Accepted Answer

Extra production?: The most common reason why the test is ordered is to see if your body is making too much catecholamines.  If the test is positive, you might need an imaging study (ct scan, mibg, mri...) to see whether or not a tumor (adrenal) is doing this.

Question 3

had catecholamine injection test . my dopamine & catecholamine levels were negative 30 & negative 60. what does that  mean if normsl range start at 0?

Accepted Answer

Cateholamine test. : Hmm. Not sure what test you had. Was it a Regitine (phentolamine) Test? Done to test for Pheochromocytoma. Urine tests rule it out if your BP was high when tested.

Question 4

can methylphenidate causehigh lvls catecholamines fractionated blod test?+mking result undifferentiat so hyperadrnrgcpots cannot be diagnosis b/c of med use?

Accepted Answer

Ritalin (methylphenidate) and POTS: Methylphenidate shows up as methampetamine in a blood test. To DX hyperadrenergic postural orthostatic tachycardia syndrome (pots) would be a clinical issue not primarily based on a blood test. I can see trying methylphenidate for the chronic fatigue aspects of pots, but the best treatment is often regular aerobic exercise.

Question 5

what if the results are negative in the 24 hour catecholamine urine test?

Accepted Answer

R/O adrenal tumor: Catecholamines are typically produced by functioing adrenal tumors causing elevated blood pressure and rapid pulse. This can be ruled out with a normal 24 hour test.

Question 6
