What is the reference range for urine amylase?

Explanation:
Urine amylase in a normal person sits at a low level because amylase is filtered and excreted in small amounts. The reference range commonly cited for urinary amylase is about 1 to 15 U/L. Values within this range are considered normal; higher numbers suggest possible pancreatic or salivary gland sources releasing more amylase into the urine, which is why ranges like 20–40 U/L or 50–100 U/L would be viewed as elevated. A range such as 0–5 U/L is at the very low end and not the typical laboratory reference interval. So, 1–15 U/L best represents the standard reference range.
