Gastrin blood tests are primarily used to evaluate the level of gastrin in the body. Gastrin blood tests may be ordered for individuals experiencing symptoms such as: abdominal pain, diarrhea, or known peptic ulcers that have not responded to medical treatment. Elevated levels of gastrin may be an indicator for a gastrin producing tumor and additional testing may be needed. This test may also be ordered after the removal of a gastrinoma to monitor and evaluate for recurrence.
