A "AIH Screening + PBC + ANA global test" refers to a blood test panel that checks for markers associated with autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and the presence of antinuclear antibodies (ANA), which can indicate an autoimmune condition across various systems in the body, often used as a broad screening tool for autoimmune diseases including AIH and PBC; essentially, it's a comprehensive test to investigate potential autoimmune liver disease by looking for specific antibodies related to these conditions.
