A stool elastase test measures the amount of elastase in your stool (poop). Elastase is a type of digestive enzyme, a protein that speeds up certain chemical reactions in your body. The pancreas, a gland that sits behind your stomach, makes these digestive enzymes to help your body break down food and absorb nutrients. Your body can then use these nutrients for energy, growth, and repairing cells.
