Catecholamines, Urinary Free, 24 Hour Urine

What’s Being Tested:

  • Catecholamines
    • Epinephrine
    • Norepinephrine
    • Dopamine

Fasting: No

Specimen: Urine (Draw Location | How It Works | FAQs)

Important Note:

  • Kit must be picked up and returned to draw station.
  • Avoid patient stress. Many drugs (reserpine and alpha methyldopa, levodopa, monoamine oxidase inhibitors, and sympathomimetic amines) may interfere and should be discontinued two weeks prior to specimen collection. Nose drops, sinus and cough medicines, bronchodilators and appetite suppressants, α2agonists, calcium channel blockers, converting enzyme inhibitors, bromocriptine, phenothiazine, tricyclic antidepressants, α- and β-blockers, and labetalol may interfere. Mandelamine® interferes, but thiazides do not. Caffeine products should be avoided before and during collection. The patient should not be subjected to hypoglycemia or exertion. Increased intracranial pressure and clonidine withdrawal can cause false-positive results.

comments: Your customer service is excellent - responsive and goes the extra mile. Worked with Rachel, who was terrific. The website lagged a lot, but may be new year's eve traffic. Also, a coupon supposed to expire on 1/1/22 did not work when ordered on 12/31/21. Overall however, your service and availability of labs, which is most important, is excellent.
