Which blood tests can check for gastroparesis?

None: There is no blood test for gastroparesis. Gastroparesis can be diagnosed based on a good history and physical exam as well as tests such as a barium swallow x-ray or a gastric emptying scintigraphy with a radioisotope. Blood tests can help diagnose the underlying problems such as diabetes, hypothyroidism or autoimmune diseases.

Mechanical problem: Gastroparesis is a mechanical or electrical problem with the motility of the gut. As such, there is not a change in blood chemistry or hormone levels to be tested for. It is diagnosed by the absence of gut movement, typically using various imaging studies such as a barium swallow or a gastric emptying study. You need to check for diabetes as the most common cause for gastroparesis --.
