Lipase optimal range and reference range

Compiled by Alina Radu, founder of Sera, from the published sources below · Last reviewed November 9, 2026

Sera's bands for Lipase:

  • Optimal 10 – 60 U/L (10 – 60 IU/L); sufficient 8 – 80 U/L (8 – 80 IU/L); out of range above 80 U/L.

Evidence grade: Published reference interval. A band that primarily reflects a published adult laboratory or population reference interval. It is not necessarily applicable to every assay or laboratory.

All units

UnitOptimalSufficientOut of range
U/L10 – 608 – 80above 80
IU/L10 – 608 – 80above 80

Bounded on the high side only — a low result is not treated as out of range. No agreed lower limit: alberta's harmonised interval and medlineplus have none, and mayo's is 13 rather than 8 or 10.

What the evidence says

More specific than amylase and raised for longer, so it survives a delayed presentation. Reference intervals differ several-fold between methods, which is why a mildly raised result has to be read against the interval on the report: Mayo Clinic Laboratories uses 13 to 60 U/L, Alberta's harmonised adult interval is below 80, and MedlinePlus quotes up to 160. Sera's bands end at the Mayo and Alberta upper limits. A low result is not flagged, because Alberta's interval and MedlinePlus set no lower limit and no source gives a low lipase a threshold.

Assay: Results differ meaningfully between platforms and methods. Compare against the interval printed by the issuing laboratory before acting on a borderline value.

Sources

  • LPS - Overview: Lipase, Serum — Mayo Clinic Laboratories, 2026 · Laboratory / reference-interval sourceReference interval 13 to 60 U/L. Matches Sera's optimal upper edge of 60; its lower limit is 13, not Sera's 10 or 8.
  • Lipase and lactate dehydrogenase (LD) updated reference intervals and implementation of lipase correction factor — Alberta Precision Laboratories (Laboratory Bulletin, 19 September 2022), 2022 · Laboratory / reference-interval sourceProvince-wide harmonised adult lipase interval is below 80 U/L with no lower limit; results differed so much between instruments that a correction factor was introduced. Matches Sera's sufficient upper edge of 80.
  • Lipase test — MedlinePlus Medical Encyclopedia, US National Library of Medicine, 2025 · Government / public-health guidanceNormal results are 0 to 160 U/L in general: twice Sera's upper edge and with no lower limit, which shows the method spread.

What Lipase measures

A fat-digesting enzyme produced almost entirely by the pancreas.

More specific than amylase and raised for longer, so it is the better single test for pancreatitis and the one that survives a delayed presentation. Reference intervals vary several-fold between methods, so read a mildly raised result against the interval on the report rather than against a remembered number.
