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.
Diagnostic tests such as blood tests, CT angiography, and barium swallow are essential for identifying upper GI bleeding. These tests help detect anemia, assess liver function, and visualize the GI tract.

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.

FAQs

What tests diagnose GI bleeding?

Blood tests, CT angiography, and endoscopy are common tests.

Why is endoscopy preferred?

It provides direct visualization and treatment of bleeding sites.

What do blood tests reveal?

Blood tests can indicate anemia and liver function issues.
