What is the purpose of catecholamines tests?

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. ...Read more

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. ...Read more

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? ...Read more

Could panic attacks cause excess levels of catecholamines in urine tests?

Could panic attacks cause excess levels of catecholamines in urine tests?

Temporary, maybe: 24 hour urine tests for catecholamines are checking for epinephrine, norepinephrine, & other compounds that can be produced by catecholamine-secreting tumors called pheochromocytomas. Panic attacks alone might temporarily raise these levels, but not in sustained fashion like one of these tumors can. When present, pheochromocytomas can cause anxiety and panic attacks and raise urine catecholamines. ...Read more

What are the other causes of elevated catecholamines in a 24 hour urine test if it is not a pheochromocytoma?

How High?: There are many causes of elevated catechols in a 24 hour urine sample. Depending on the test used medications can interfere with catechol levels, including things as simple as acetaminophen & certain beta blocker medications. If only mildly elevated something as simple as stress can elev the labs. There is a cond called a paraganglioma. The cond's make diff catechols, the breakdown is helpful. ...Read more

Get checked for diabetes .Treatment depends on the underlying condition . Avoidance of sudden rising up will minimize the sx. If there's a regular drop in blood pressure, there are meds to sustain normal bp. Pls read link below. ...Read more
