Catecholamine urine test

Female urinary tract

Male urinary tract

This is a test that measures the level of catecholamines or catecholamine metabolites (break-down products) in the urine.

Dopamine-urine test; Epinephrine-urine test; Adrenalin-urine test; Vanillylmandelic acid (VMA); Urine metanephrine; Normetanephrine; Norepinephrine-urine test; Urine catecholamines; VMA; HVA; Metanephrine; Homovanillic acid (HVA)

For this test, you must urinate into a special bag or container every time you use the bathroom for 24-hour period.

• On day 1, urinate into the toilet when you wake up in the morning. Close the container tightly. Keep it in the refrigerator or a cool place during the collection period.
• Urinate into the special container every time you use the bathroom for the next 24 hours.
• On day 2, urinate into the container in the morning again when you wake up.
• Label the container with your name, the date, the time of completion, and return it as instructed.

For an infant:

Thoroughly wash the area around the urethra (the hole where urine flows out). Open a urine collection bag (a plastic bag with an adhesive paper on one end). For males, place the entire penis in the bag and attach the adhesive to the skin. For females, place the bag over the two folds of skin on either side of the vagina (labia). Put a diaper on the baby (over the bag).

The infant should be checked frequently and the bag changed after the infant has urinated. Empty the urine from the bag into the container provided by your doctor.

Because lively infants can cause the bag to move, this procedure may take a couple of attempts. Extra collection bags may be necessary.

When finished, label and return the container as instructed.

A blood sample can also measure catecholamines.

A health care provider will tell you whether or not to discontinue any drugs or activities that may interfere with the test.

Certain foods can increase urinary catecholamines, including coffee, tea, bananas, chocolate, cocoa, citrus fruits, and vanilla. Avoid these for several days prior to the test.
