Metanephrine-Free Test

Metanephrine-Free test is a diagnostic tool that measures the amount of metanephrine, a metabolite of adrenaline, in the urine. This test is generally used to diagnose or monitor conditions such as pheochromocytoma or paraganglioma, which are rare tumors of the adrenal glands that can overproduce catecholamines like adrenaline.

  • Profile Name: Metanephrine-Free Test
  • Sample Type: UR(Urine)
  • Preparations Required: No special preparation is needed for this test. Continue with your regular medications unless advised otherwise by your healthcare provider.
  • Report Time: 24 hours

Adrenaline is a hormone that your body releases when you're under stress, and metanephrine is what remains when your body breaks down this hormone. The levels of metanephrines in your body can fluctuate, which is why this test measures the amounts excreted in your urine over 24 hours. High levels can be indicative of a problem with your adrenal glands.
