A member asked:

Why do different labs set different limits for the high limit of amylase (some 100, some 110 others 140) ? my recent amylase level is 140. but the high limit of the lab i used is 110ul making my level high. but if another lab did it, id be normal?

No, you can't make that assumption because there is no standardization about normal amylase level among the laboratories so each lab has its own normal range. Your result has to be interpreted by the lab where the test is done. However, you should not concern much about an amylase level of 140 though because this abnormal result alone does not have much meaning. Take care.

Your amylase is slightly high as it has to be compared against the range provided by the respective lab. Such values are to be interpreted by ordering doc in the clinical context in which they they were ordered. Repeating same test after some time usually provides information about their provenience and significance based on actual trend.
