New blood test may sharpen diagnosis of autoimmune liver disease

NCT ID NCT05810480

First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time

Summary

This study evaluates whether a blood test measuring polyreactive immunoglobulin G (pIgG) can more accurately diagnose autoimmune hepatitis (AIH) and distinguish it from other liver conditions. Researchers will collect blood samples from 400 adults undergoing liver biopsy for suspected liver disease. The goal is to see if pIgG testing improves upon standard autoantibody tests, especially in cases where conventional tests are negative or misleading.
