Catecholamines and Metanephrines, Fractionated, 24-Hour Urine

The 5 tests in this panel

What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.

• Metanephrine, 24-Hour Urine

  Measures metanephrine, a breakdown product of adrenaline, in all the urine you collect over 24 hours. Doctors use it to look into adrenal gland tumors.

  Men, 18+

  58–276 µg/24 h

  Women, 18+

  36–209 µg/24 h

• Normetanephrine, 24-Hour Urine

  Measures normetanephrine, a breakdown product of norepinephrine, in all the urine you collect over 24 hours. Doctors use it to look into adrenal gland tumors.

  Men, 21–30

  110–553 µg/24 h

  Men, 31+

  156–729 µg/24 h

  Women, 21–30

  95–449 µg/24 h

  Women, 31+

  131–612 µg/24 h

• Total Metanephrines, 24-Hour Urine

  The combined amount of metanephrine and normetanephrine in your urine over 24 hours. Doctors use it to look into adrenal gland tumors.

  Men, 18–29

  190–583 µg/24 h

  Men, 30–39

  200–614 µg/24 h

  Men, 40–49

  211–646 µg/24 h

  Men, 50–59

  222–680 µg/24 h

• Urine Creatinine, 24-Hour

  Total creatinine in all the urine you pass over 24 hours. It mostly reflects muscle mass and helps show whether a 24-hour collection was complete.

  Men, 18–50

  1,000–2,500 mg/24 h

  Women, 18–50

  700–1,600 mg/24 h

  Men, 51–80

  800–2,100 mg/24 h

  Women, 51–80

  500–1,400 mg/24 h

• Urine Volume, 24-Hour

  The total amount of urine you pass in 24 hours. It reflects how much fluid you take in and lose, and it is needed to read other 24-hour urine tests.

  Adults

  800–2,000 mL/24 h
