Overview
Laboratory Findings
Following laboratory tests are used to diagnose autoimmune hepatitis:
- Liver function tests
- Alkaline phosphatase
- Antibody assays
- Serum protein and immunoglobulins
- Complete blood count and differential count
- Platelet count
- ESR
- Coombs test
- Peripheral blood film
Laboratory findings consistent with the diagnosis of Autoimmune hepatitis include:
- Increased serum aminotransferase levels (1.5-50 times reference values)
- Increased serum immunoglobulin levels, primarily immunoglobulin G (1.2 to 3.0 times normal)
- Seropositive for ANAs, anti-actin, SMAs, LKM-1, anti-liver cytosol 1 (anti-LC1) antibodies, SLA/LP autoantibodies or pANCA
