Metanephrine Level: Normal and High

Metanephrine level is part of the result of Urine Metanephrine test. It could help diagnose adrenal tumor and other problems.

In general, the metanephrine level is either normal or higher than normal.

Normal Range:

  • Male:
    • 3 to 8 years: 29-92 mcg/24 hours
    • 9 to 12 years: 59-188 mcg/24 hours
    • 13 to 17 years: 69-221 mcg/24 hours
    • ≥18 years: 44-261 mcg/24 hours
    • For hypertensives: <400 mcg/24 hours
  • Female:
    • 3 to 8 years: 18-144 mcg/24 hours
    • 9 to 12 years: 43-122 mcg/24 hours
    • 13 to 17 years: 33-185 mcg/24 hours
    • ≥18 years: 30-180 mcg/24 hours
    • For hypertensives: <400 mcg/24 hours

Interpretations:

  • A normal level means there are no adrenal tumors detected.
  • On the other hand, a high metanephrine level suggests the possible presence of pheochromocytoma (a rare, usually noncancerous tumor).
