What is the role of catecholamine in the diagnosis of hypertension (high blood pressure)?

Clinically, the measurement of circulating catecholamines is valuable in the diagnosis of catecholamine secreting tumors associated chiefly with hypertension (pheochromocytomas, neuroblastomas and gangliomas) and with the evaluation of orthostatic hypotension.

Why are 24-hour urine tests used to diagnose pheochromocytoma?

Since a 24-hour urine collection represents a longer sampling time than a random, or symptom-directed serum sample, and because catecholamine secretion by pheochromocytomas is intermittent, the urine test may detect some cases missed by a blood level.

What is the pH of a 24 hour urine sample?

What is the function of catecholamines?

What does catecholamines do to the body?

Catecholamines are important in stress responses. High levels cause high blood pressure which can lead to headaches, sweating, pounding of the heart, pain in the chest, and anxiety. Examples of catecholamines include dopamine, epinephrine (adrenaline), and norepinephrine (noradrenaline).

What are catecholamines hormones?

Include 24-hour total urine volume on the test request form and date and time collection started and finished. Note: If original container is received with pH >3, but <5, adjust pH to <3 with 6N HCl.

What does "free" mean in a urine test?

The expression “free” in free catecholamine fractionation means unconjugated. This assay is of most value for pheochromocytoma when specimen is collected during a hypertensive episode. Since a 24-hour urine collection represents a longer sampling time than a random, or symptom-directed serum sample, and because catecholamine secretion by pheochromocytomas is intermittent, the urine test may detect some cases missed by a blood level.
