Reference Values for Pheochromocytoma Lab Tests

Pheochromocytomas are tumors that affect the production of certain hormones and may cause symptoms of diabetes.

Therefore, in order to help diagnose, doctors usually order certain lab tests to measure the hormone levels and glucose (blood sugar) level.

In general, pheochromocytoma lab tests include: catecholamine test (urine and blood), glucose test (urine and blood), and metanephrine test (urine and blood). Here are the reference values.

Catecholamine

urine test:

  • Norepinephrine:
    • <1 year: 0 to 11 mcg
    • 1 year: 1 to 17 mcg
    • 2 to 3 years: 4 to 29 mcg
    • 4 to 6 years: 8 to 45 mcg
    • 7 to 9 years: 13 to 65 mcg
    • ≥10 years: 15 to 80 mcg
  • Epinephrine:
    • <1 year: 0 to 2.6 mcg
    • 1 year: 0 to 3.6 mcg
    • 2 to 3 years: 0 to 6.1 mcg
    • 4 to 9 years: 0.2 to 10.0 mcg

    • ≥16 years: 0 to 21 mcg

  • Dopamine:
    • <1 year: 0 to 86 mcg
    • 1 year: 10 to 140 mcg
    • 2 to 3 years: 40 to 260 mcg

Blood test:

  • Norepinephrine:
    • Supine: 70 to 750 pg/mL
    • Standing: 200 to 1,700 pg/mL
  • Epinephrine:
    • Supine: 0 to 111 pg/mL
    • Standing: 0 to 141 pg/mL
  • Dopamine: 0 to 30 pg/mL

Glucose

Urine test: 0 to 15 mg/dL

Blood test:

  • 0 to 11 months: not established
  • ≥1 year: 70 to 140 mg/dL

Metanephrine

Urine test:

  • 0 to 2 years: 82 to 418 mcg/g creatinine
  • 3 to 8 years: 65 to 332 mcg/g creatinine
  • 9 to 12 years: 41 to 209 mcg/g creatinine
