The best test for abdominal pain depends on the underlying cause of the pain. Common tests used to diagnose abdominal pain include imaging tests such as X-rays, ultrasound, CT scans, and MRI; laboratory tests such as blood tests and stool tests; and endoscopic procedures such as colonoscopy and endoscopic ultrasound.
X-rays can help diagnose abdominal pain caused by a break in a bone, a blocked intestine, or a foreign object. Ultrasound can detect problems in the abdominal organs, such as gallstones or an enlarged liver. CT scans can provide more detailed images of the abdominal organs and can help diagnose problems such as a hernia, tumors, or appendicitis. MRI can be used to diagnose abdominal pain caused by injury or inflammation of the organs, such as the liver or gallbladder.
Laboratory tests are used to diagnose abdominal pain caused by infection or inflammation. Blood tests can detect the presence of infection or inflammation. Stool tests can be used to detect parasites, bacteria, or viruses that can cause abdominal pain.
Endoscopic procedures are used to diagnose abdominal pain caused by conditions such as ulcers, polyps, or tumors. Colonoscopy is a procedure used to examine the entire colon and can detect polyps or tumors. Endoscopic ultrasound can be used to examine the pancreas, gallbladder, and bile ducts.
The best test for abdominal pain depends on the underlying cause of the pain. Your doctor may order a combination of tests to diagnose the cause of your abdominal pain.
