Metanephrine - Free near me in Indore









The Metanephrine - Free test is a blood test that checks the level of free metanephrines. These are the substances formed when stress hormones like epinephrine, norepinephrine break down. It helps doctors detect pheochromocytoma, a rare adrenal gland tumor that causes excess hormone release. This test is widely available in Indore with Tata 1mg labs at an affordable price.
Doctors may suggest this test if signs of excess adrenaline-like hormone are present, or if a tumor like pheochromocytoma is suspected based on symptoms or scan results. It is also used to monitor individuals who have had these tumors in the past. This test can be done if there are symptoms like high blood pressure that comes and goes, a fast heartbeat, headaches, sweating, etc.
An overnight fast for 8–12 hours is required before the test. Do not consume foods like bananas, pineapples, chocolate, coffee/caffeine, ice cream, vanilla, potatoes, B-complex supplements, high-cereal diets, nicotine/tobacco, and alcohol for at least 48 hours before sample collection. Also, avoid strenuous exercise and stress for at least 24 hours before collection. It is advised to rest quietly by lying down for 20–30 minutes before blood collection.
Do not stop prescribed medicines without your doctor's advice and inform the laboratory and your doctor about all medicines and supplements you are taking. Some medicines can affect results (e.g., certain antidepressants, decongestants/sympathomimetics, amphetamines, labetalol, sotalol). A doctor's prescription is required for the test.








What does Metanephrine - Free measure?
The Metanephrine - Free test measures the level of free metanephrine in the blood. Metanephrine is a substance formed when the body breaks down epinephrine (adrenaline). An increased level of metanephrine may be associated with excess catecholamine production and can occur in conditions such as pheochromocytoma. However, elevated levels can also result from certain medicines, physiological stress, or other factors. Therefore, the test result should be interpreted by a doctor in combination with the individual's symptoms, medical history, and other clinical findings. The test may be recommended when pheochromocytoma is suspected or for follow-up evaluation in individuals with a previous history of the condition.
