Catecholamines, such as dopamine and adrenaline, are hormones that the brain, nerve tissues, and adrenal glands produce. They are responsible for the body’s “fight-or-flight” response.

CATECHOLAMINE-producing tumors arising from tissue outside the adrenal medulla have long been recognized as causes of sustained or paroxysmal hypertension. 1 Their origin has traditionally been ...

Catecholamines are hormones produced by the adrenal glands, which sit on top of the kidneys. Dopamine, epinephrine (adrenaline), and norepinephrine are the main catecholamines. Each of these ...

The catecholamine blood test measures the amount of catecholamines in your body. “Catecholamines” is an umbrella term for the hormones dopamine, norepinephrine, and epinephrine, which ...

PROMINENT among the symptoms of familial dysautonomia are the manifestations of autonomic dysfunction.1 A disturbance in catecholamine metabolism has been documented by the demonstration of high ho ...

Types of Catecholamine Tests. Catecholamines can be measured by a urine test or a blood test. Urine tests are more common, but your doctor may want to do both to get more information.

A case of fetal neuroblastoma of the right adrenal gland, with rapid development of hydrops fetalis due to catecholamine-induced cardiomyopathy, is reported. A fetus with a right suprarenal mass ...

Infants with catecholamine-resistant hypotension had significantly lower levels of systemic vascular resistance and postoperative cortisol concentration.

This discrepancy may be explained by the development of catecholamine resistance due to chronic sympathetic overactivation, leading to diminished physiological responses despite elevated NE levels.

Catecholamines, like adrenaline and dopamine, are chemical messengers released in response to emotional or physical stress. Catecholamines prepare the body to take action. High or low levels can cause ...

Catecholamine urine testing (CATU) is used to diagnose certain diseases that increase catecholamine production. The test is often combined with a catecholamine blood test. Levels can fluctuate, so ...
