overlap in values between UP and systemic mastocytosis, and urinary NMH measurements should not be
relied upon alone in distinguishing localized from systemic disease. Up to 25% variability in spot-urine
excreted levels may be observed, making 24-hour urine collections preferable for cases with borderline
results. Children have higher NMH levels than adults. By the age of 16 adult levels have been reached.
Reference Values:
0-5 years: 120-510 mcg/g creatinine
6-16 years: 70-330 mcg/g creatinine
