How is blood work used to diagnose EPI?

ANSWER

Your doctor will take a sample of your blood and send it to a lab to check it for anemia, a condition in which your body doesn’t have enough healthy red blood cells. The lab will also test your blood for vitamin B12, iron, and folate. If the levels are too low, that can mean EPI is keeping your body from absorbing these nutrients.

The lab might also look for a chemical your pancreas makes to help with digestion called trypsinogen. A level that’s too high is a sign of a problem.
