Test Includes

Plasma catecholamines, fractionated (dopamine, epinephrine, norepinephrine)

Use

This test is used for measurement of fractionated catecholamines in plasma.

Diagnose pheochromocytoma and those paragangliomas which may secrete epinephrine, norepinephrine, or both. Such tumors may cause paroxysmal or persistent hypertension. Investigation of hypertensive patients, especially younger individuals, particularly when hypertension is paroxysmal, suggesting pheochromocytoma. Plasma catecholamines with urinary metanephrines and VMA are a recommended test battery for pheochromocytoma.3 Others recommend plasma catecholamines when urinary collections are not diagnostic. Work up multiple endocrine adenomatosis, type II. Used also in diagnosis of disorders related to the nervous system and in assessment of resuscitation.4

This test is used for measurement of fractionated catecholamines in plasma.

Limitations

This test was developed, and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.

As the secretion of catecholamines from pheochromocytoma and paragangliomas is episodic; a single estimation of plasma or urinary catecholamines will miss the biochemical diagnosis in about 30% of cases.1,2

Many alterations in physiologic and pathologic states can profoundly affect catecholamine concentrations. Any environmental factor that may increase endogenous catecholamine production should be avoided. These include noise, stress, discomfort, body position and the consumption of food, caffeinated beverages or nicotine. Caffeine and nicotine effects are short term, a few minutes to hours only.

Other substances and drugs that may also affect the results include:

  • Medications that inhibit reuptake of norepinephrine and epinephrine, such as serotonin-norepinephrine reuptake inhibitors (e.g., venlafaxine), selective serotonin reuptake inhibitors, and tricyclic antidepressants, result in increased concentrations of norepinephrine and epinephrine.3
  • Monoamine oxidase inhibitors block conversion of norepinephrine and epinephrine to nonfunctional metabolites raising circulating catecholamine levels.3
  • Sympathomimetic substances such as amphetamine, caffeine, nicotine and decongestants (ephedrine, pseudoephedrine, phenylephrine) increase the release of norepinephrine and epinephrine.4-6
  • Other medications such as acetaminophen, alpha-methyldopa and levodopa can also result in false-positive biochemical testing.3,4,7,8
  • Antiparkinsonian drugs (Levodopa, carbidopa) can increase plasma dopamine levels.5,9
  • Substances that reduce or increase plasma volume acutely (e.g., diuretics, radiographic contrast media, synthetic antidiuretic hormone) can artificially increase catecholamine levels.
  • The use of cocaine as well as amphetamines such as ecstasy (3,4-methylenedioxymethamphetamine or MDMA) was reported to be associated with increased plasma catecholamine concentrations in the absence of pheochromocytoma.10-12
  • Cigarette smokers may have increased plasma and urinary catecholamines and/or metanephrine levels as nicotine stimulates catecholamine release by activation of nicotinic acetylcholine receptors in the brain and the adrenal medulla.13
  • Caffeine can increase circulating catecholamines secondary to its stimulatory effects.10
  • Catecholamine-rich foods (bananas, fruit juices, nuts, tomatoes, potatoes and beans) are major sources of diet-associated FP results.14,15
  • Foodstuffs containing large amounts of tyramine such as hard cheeses and red wine can cause release of vesicular NE leading to FP test results.16

Plasma levels are useful if elevated, especially during or immediately following an episode of hypertension, but false-negatives occur when the specimen is drawn during an uneventful period. Normotensive pheochromocytoma has been reported.5 False-positive results are common. Epinephrine secretion increases in response to cold and hypoglycemia. Drugs which may affect plasma norepinephrine levels include α- and β-adrenergic blockers, vasodilators, clonidine, bromocriptine, theophylline, phenothiazine, tricyclic antidepressants, labetalol, calcium channel blockers, converting enzyme inhibitors, bromocriptine, chlorpromazine, haloperidol, and cocaine. Plasma catecholamines are less sensitive than are urinary catecholamines.6

Custom Additional Information

The catecholamines (dopamine, epinephrine, and norepinephrine) are derived from tyrosine via a series of enzymatic conversions.17 All three catecholamines are important neurotransmitters in the central nervous system and play a crucial role in the autonomic regulation of many homeostatic functions, namely, vascular tone, intestinal and bronchial smooth muscle tone, cardiac rate and contractility and glucose metabolism. Their actions are mediated via alpha- and beta-adrenergic and dopamine receptors, all existing in several subforms. The three catecholamines overlap but differ in their receptor activation profile and consequent biological actions. The systemically circulating fraction of the catecholamines is derived almost exclusively from the adrenal medulla, with small contributions from sympathetic ganglia.

Catecholamines are normally present in the plasma in minute amounts, but levels can increase dramatically and rapidly in response to change in posture, environmental temperature, physical and emotional stress, hypovolemia, blood loss, hypotension, hypoglycemia and exercise. Elevation of plasma-free metanephrines less than three to four times the normal level might represent potential false-positive results.4 In many cases, this is secondary to inappropriate sampling and should be repeated with the patient in the supine position. A false-positive result commonly shows elevations in either metanephrine or normetanephrine, but not both. Very high false-positive levels (three-fold or higher) are rare, and catecholamine related disease should be suspected in such cases.1,4

Pheochromocytoma and Paragangliomas:

These rare neuroendocrine tumors arise from chromaffin cells of the adrenal medulla (pheochromocytoma) or neural crest progenitors located outside of the adrenal gland (paraganglioma).1,2,4 These tumors are derived from either sympathetic tissue in the adrenal or extra-adrenal abdominal locations or from parasympathetic tissue in the thorax or head and neck. In patients with pheochromocytoma (a potentially curable tumor of catecholamine-producing cells of the adrenal medulla) or, less commonly, paraganglioma (a tumor of the sympathetic ganglia that also produces catecholamine), plasma catecholamine levels may be continuously or episodically elevated. This results in episodic or sustained hypertension and intermittent attacks of palpitations, cardiac arrhythmias, headache, sweating, pallor, anxiety, tremor, and nausea.2,7,18

Plasma catecholamines should not be used as the first-line test for pheochromocytoma, as plasma catecholamine levels may not be continuously elevated but only secreted during a "spell." By contrast, production of metanephrines (catecholamine metabolites) appears to be increased continuously.

The recommended first-line laboratory tests for pheochromocytoma1,2,19 include:

However, plasma catecholamine measurements can be useful in patients whose plasma metanephrine or urine metanephrine measurements do not completely exclude the diagnosis.5

A dopamine-secreting paraganglioma is a very rare subtype that predominantly or exclusively secretes dopamine but not norepinephrine or epinephrine. These malignancies have been characterized by a lack of catecholamine excess symptoms, large tumor size, extra-adrenal location and high malignant potential.20-22

Neuroblastoma:

Intermittent or continuous elevations of the plasma levels of one or several of the catecholamines may be observed in patients with neuroblastoma and related tumors (ganglioneuroblastomas and ganglioneuromas) and, very occasionally, in other neuroectodermal tumors.5,23 Vanillylmandelic acid, homovanillic acid and urine catecholamine measurements are the mainstay of biochemical diagnosis and follow-up of these tumors. Plasma catecholamine levels can aid diagnosis in some cases, but diagnostic decision levels are not well established. The most useful finding is disproportional elevations in one of the three catecholamines, particularly dopamine, which may be observed in these tumors.

Autonomic Neuropathy:

Inherited and acquired syndromes of autonomic dysfunction or failure and autonomic neuropathies are characterized by either inadequate production of one or several of the catecholamines or by insufficient release of catecholamines upon appropriate physiological stimuli (e.g., change in posture from supine to standing, cold exposure, exercise, stress).24 Depending on the underlying cause and pathology, autonomic dysfunction or failure and autonomic neuropathies are associated with subnormal resting norepinephrine levels or an absent rise of catecholamine levels in response to physiological release stimuli (e.g., change in posture from supine to standing, cold exposure, exercise, stress), or both.

The adrenal medullary catecholamines (epinephrine, norepinephrine, and their precursor, dopamine) are rapidly metabolized materials with intense vasoactivity, among many other properties. They can be synthesized by extra-adrenal cells or neoplasms of the APUD system. They are pathogenic in the episodic hypertension of pheochromocytoma, and will be elevated during and immediately after such a paroxysm. However, levels may be normal during asymptomatic intervals. Urine catecholamines, metanephrines, VMA, and HVA provide additive information. A clonidine-suppression test has been described; failure to suppress plasma catecholamines with clonidine supports the diagnosis.7-9

Patient Preparation

Patient should discontinue drugs and other substances that may affect measured catecholamine results for at least one week before obtaining the specimen (see Limitations for details).

Patient should not be smoking for four to six hours. Walnuts, bananas, and α-methyldopa (Aldomet®) should be avoided for a week prior to sampling. Other drug interference may occur, including epinephrine and epinephrine-like drugs (eg, nosedrops, sinus and cough preparations, bronchodilators, appetite suppressants). Test is unreliable in subjects on levodopa or methenamine mandelate. Avoid patient stress.2 See Limitations. An indwelling heparinized venous catheter is advocated, since venipuncture can cause an increase in the substances for which testing is being done. Patient should remain supine in quiet surroundings for at least 30 minutes.

Patient should discontinue drugs and other substances that may affect measured catecholamine results for at least one week before obtaining the specimen (see Limitations for details).

Causes for Rejection
