Overview

Blood tests to check levels of liver enzymes are the first step in diagnosing cholangitis. Doctors can confirm the diagnosis using cholangiography, which provides pictures of the bile ducts.

Other Diagnostic Studies

Blood Tests

A routine blood test can show:[1]

Blood cultures are often performed in people with fever and evidence of acute infection. These yield the bacteria causing the infection in 36% of cases, usually after 24–48 hours of incubation. Bile, too, may be sent for culture during endoscopic retrograde cholangiopancreatography (ERCP). The most common types of bacteria linked to cholangitis are gram-positve and gram-negative.[1]
