Published: Oct 21, 2023
Diagnosing upper GI bleeding requires precise tests. Let's look at how these tests work and what they reveal.

Laboratory Tests
Blood tests are often the first step in diagnosing upper GI bleeding. They can reveal anemia, which indicates blood loss, and check for liver function abnormalities that might suggest variceal bleeding. Coagulation studies help identify any bleeding disorders.
Imaging Techniques
CT angiography can detect active bleeding by highlighting blood flow in the GI tract. This non-invasive imaging is often used when endoscopy isn't possible. In some cases, a barium swallow may be used to visualize the esophagus and stomach, although it can interfere with other tests.
Endoscopy as a Diagnostic Tool
Endoscopy is the gold standard for diagnosing upper GI bleeding. It allows direct visualization of the bleeding site and can often provide immediate therapeutic intervention. This test is typically performed within 24 hours of symptom onset.
