What is Metanephrines Fractionated Free, Plasma?
This blood test measures the levels of metanephrines, which are breakdown products of hormones like adrenaline and noradrenaline. It helps doctors investigate symptoms that might suggest an overproduction of these hormones.
Why is this test important?
The test is crucial for diagnosing rare tumors called pheochromocytomas and paragangliomas, which can cause high blood pressure, headaches, and palpitations. Monitoring these levels helps confirm the presence of such tumors and guide treatment.
How to Prepare
Fasting for at least 8-10 hours is usually required. You may also need to avoid certain medications, foods, and beverages (like caffeine) before the test. Please follow specific instructions from your doctor.
