The plasma free metanephrine test is a sophisticated diagnostic procedure that helps medical professionals identify potentially serious health issues. At IntroLab, we are dedicated to offering detailed information about various tests. We ensure that you are well-informed about all crucial aspects of this analysis. By adhering to the highest standards, our laboratory delivers reliable and accurate results, aiding in timely diagnoses.

What is plasma free metanephrine?

Plasma free metanephrine refers to the concentration of free metanephrines in blood plasma. Metanephrines are metabolites of catecholamines – adrenaline and noradrenaline, hormones that are crucial for our body’s response to stress. ‘Free’ in this context means that the metanephrines are freely circulating in the plasma, not bound to other molecules.

Why is measuring plasma free metanephrine important?

Metanephrines are normally present in small amounts in our body, but elevated levels can indicate the presence of pheochromocytoma, a rare adrenal gland tumor that excessively produces catecholamines. These tumors can cause serious symptoms and complications, including high blood pressure, sweating, headaches, and heart palpitations.

When is a plasma free metanephrine test necessary?

Your doctor may recommend a plasma free metanephrine test if you have symptoms suggesting pheochromocytoma or if there is suspicion of this condition based on other diagnostic tests. Additionally, this test may be necessary for monitoring patients previously diagnosed with this condition.

High values

Elevated levels of plasma free metanephrine are typically an indicator of several potential health issues, including:

  • Pheochromocytoma: This is the most common cause of elevated plasma free metanephrine levels. Pheochromocytoma is a rare adrenal gland tumor that can lead to excessive production of catecholamines.
  • Paraganglioma: These are rare tumors that develop in ganglia cells, structures that are part of our autonomic nervous system. These tumors can also produce excessive amounts of catecholamines.
  • Certain medications: Some drugs, such as tricyclic antidepressants, can lead to elevated plasma metanephrine levels.
  • Stressful situations: Acute stress can lead to excessive production of catecholamines, which can temporarily increase plasma metanephrine levels.

Low values

Low levels of plasma free metanephrine are generally not considered problematic, but it is still important to understand the possible reasons for these low levels:

  • Normal variation: The amount of plasma free metanephrine can vary throughout the day, and low values may simply reflect normal variation.
  • Effect of medications: Some medications can potentially reduce plasma metanephrine levels.
  • Genetic factors: Some people naturally produce fewer catecholamines, which can lead to lower levels of plasma metanephrine.

Each result must be interpreted in the context of the individual patient, taking into account their medical history, current symptoms, and results from other relevant tests.

Association with other tests

Plasma metanephrine tests are often used in combination with other tests to establish an accurate diagnosis. Other tests may include:

  • Urine tests: These can be used to measure levels of catecholamines and metanephrines in the urine. These tests can be especially useful for detecting episodic changes in catecholamine production that might not be captured in a single blood test.
  • Imaging tests: Your doctor may order CT or MRI scans to visualize the adrenal glands or other parts of the body where tumors might be present.
  • Genetic testing: In some cases, pheochromocytoma may be associated with genetic disorders. Genetic testing can help identify these disorders.
  • Blood pressure tests: Since pheochromocytoma can cause high blood pressure, your doctor may monitor your blood pressure over time.

It is always important for patients to discuss all tests and procedures with their doctors to understand what each test involves and how the results will impact their treatment plan.

Vrsta uzorka i vreme kada se uzima uzorak

Uzorak: EDTA-plasma (venous blood)

Obrtno vreme: 8 days

Priprema: Blood is drawn after an overnight fast. If you are taking medications such as methyldopa or epinephrine-based drugs, consult your doctor before testing. Ideally, you should sit quietly for 30 minutes before the blood draw. For instructions on collecting a 24-hour urine sample, please contact the laboratory.
