Experience with serum elastase-1 testing?

Hello

I’m currently in the process of a series of tests by my GP to determine chronic pancreatitis or other pancreatic damage due to GLP-1 use, that is suspected by my Dr.

I was given a serum/blood elastase-1 test and the results were over twice the range (0-300), plus continued elevated lipase and amylase, consistent with previous tests over the last 3 weeks.

I can’t find much info on the serum elastase test, only fecal elastase tests. Does anyone in this community have experience with the blood test?

I am not looking for a diagnosis, just any info on how this test is used to characterize CP, if at all.

I have not been able to speak with my doctor about the results yet. I’m waiting on the next appt.

Thank you.
