What is Nor-Metanephrine-Free Plasma?
This blood test measures the levels of nor-metanephrine, a hormone metabolite, in your plasma. It is primarily used to screen for and help diagnose specific rare tumors that produce excessive amounts of certain hormones.
Why is this test important?
Elevated levels of nor-metanephrine can indicate the presence of pheochromocytoma or paraganglioma, tumors of the adrenal glands or nervous system. Early and accurate diagnosis is crucial for effective treatment and management of these conditions, which can cause high blood pressure and other symptoms.
How to Prepare
Fasting for at least 8-10 hours is typically required. You may also need to avoid certain foods, beverages (like caffeine), and medications for a period before the test. Please follow specific instructions provided by your healthcare provider.
