What Is Catecholamines Test?

The catecholamine blood test assesses the amount of catecholamines in your body. Catecholamines are a group of hormones mainly dopamine, norepinephrine, and epinephrine. These hormones are produced by adrenal glands (a small gland that is located above your kidneys). Your doctor may recommend these catecholamines tests to check the presence of adrenal tumors in adults. These tests are also beneficial in checking neuroblastomas, cancer that presents in the sympathetic nervous system in children. During stress, your body makes more catecholamines. These hormones are prepared by your body by making your heart beat faster and uplifting your blood pressure.

Why do you need this test?

The catecholamine blood test checks the levels of catecholamines in your blood. Your doctor will recommend this test if you have a pheochromocytoma. This is a type of tumor is commonly present in your adrenal gland. Though most pheochromocytomas are benign, you need to remove them so that they don’t hamper the functions of the adrenal.

The symptoms of pheochromocytoma are

  • High blood pressure
  • Increased heartbeat
  • An abnormal hard heartbeat
  • Heavy sweating
  • Excessive headaches on and off
  • Pale skin
  • Unexplained weight loss
  • Unnecessary frightened for no reason
  • Unexplained anxiety

 

Your doctor may also suggest this test if your child has neuroblastoma. This is a common childhood cancer that hampers 6% of children in the world.

Some symptoms of neuroblastoma are,

  • Painless lumps under the skin
  • Abdominal pain
  • Chest pain
  • Back pain
  • Bone pain
  • Inflammation of the legs
  • Wheezing
  • High blood pressure
  • Rapid heartbeat
  • Diarrhea
  • Bulging eyeballs
  • Dark areas around the eyes
  • Unexpected weight loss
  • Fever

 

The Test Preparation

You may need to do fasting for 10-12 hours before the test. Certain medications may hamper the test results. These medications could be,

  • Acetaminophen
  • Amphetamine
  • Cold and sinus medications
  • Antidepressants
  • Diuretics, such as furosemide
  • Insulin
  • Lithium
  • Tetracycline
  • Vasodilators, like hydralazine (relaxes narrow blood vessels)

 

If you are taking these medications, you must inform your doctor about the same.

The Test Procedure

Catecholamines Urine Test

If your healthcare provider mentions this test, then you need to follow the below-mentioned steps.

  • On day 1, urinate into the toilet when you wake up in the morning
  • Urinate into the special container that has been given to you by the laboratory 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

 

Catecholamines Blood Test

  • A technician or nurse will clean the site preferably the upper side of your arm with an antiseptic
  • He may ask you to remain seated or to lie down for half an hour before your test
  • After tying an elastic band around your upper arm, he will identify the vein
  • He will insert the needle into the vein and draw your blood sample into a tube
  • Finally, he will take off the elastic band and the needle
  • A bandage or gauze will be placed at the puncture site

 

The Interpretation of the Test Results

The levels of catecholamines in your body change based on your positions like standing, sitting, or lying down.

The test measures catecholamines by picogram per milliliter (pg/mL); a picogram is one-trillionth of a gram.

Norepinephrine

  • Lying down: 70–750 pg/mL
  • Standing: 200–1,700 pg/mL

 

Epinephrine

  • Lying down: undetectable up to 110 pg/mL
  • Standing: undetectable up to 140 pg/mL

 

Dopamine

  • Less than 30 pg/mL with no change in posture

 

The levels of catecholamines change significantly in children due to their rapid growth. High levels of catecholamines in adults or children may indicate that the person is having neuroblastoma or a pheochromocytoma. More tests are needed to confirm the condition.
