Dual Positivity for AMA / AMA ‐ M2 and Anti‐gp210/sp100 Shows Highest Diagnostic Value for Primary Biliary Cholangitis

Key Points

• The research aims to evaluate the diagnostic value of dual positivity for specific antibodies in primary biliary cholangitis (PBC).
• Comparison of antibody positivity in diagnosing PBC against histopathology.
• Assessment of dual positivity for AMA/AMA-M2 and anti-gp210/sp100.
• Dual positivity for AMA/AMA-M2 and anti-gp210/sp100 demonstrated the highest diagnostic accuracy for PBC.
• Findings emphasize the significance of specific antibody testing in clinical diagnostics.
