Recumbant: <375 pmol/L (This relies on the patient lying down for at least 4 hours). Standing: <750 pmol/L

For paediatric ranges (from http://hyper.ahajournals.org/content/56/3/391.full)

95th Percentile = 491 pmol/L

5th Percentile = 69 pmol/L

Reported as a comment:

• Adult males and pre-menopausal females: <1.0 IU/L
• Post-menopausal or mid-cycle females: <3.0 IU/L

Pregnancy - there is a 0.1% cross reaction with hCG resulting in very high ASU results in pregnancy.

Results should be interpreted along with the serum LH, FSH and TSH results and renal function tests.

Alpha carotene <0.25 umol/L

Beta carotene 0.19-0.89 umol/L
