DIAGNOSTIC TEST 018

Autoimmune Liver Disease Screen

Diagnostic test for LKM-1, LC-1, AMA-M2, M2-3E (BPO), Sp100, PML, gp210, SLA/LP, and Ro-52. For suspicion of autoimmune liver disease.

Indication

Suspicion of autoimmune liver disease

Sample material

Serum

  • Minim. volume: 0,5 mL

Transport

  • Within Sweden: room temperature
  • International: cold

Method

Immunoblot

Reference interval

<11 negative

Result

Results are reported as negative or positive with reaction intensity.

Interpretation

  • Antibodies against mitochondrial (AMA) type M2 are a marker for manifest or future development of primary biliary cholangitis (PBC) and occur in just over 90% of the cases. In PBC, a strongly positive reaction for AMA-M2 is usually detected. Weakly positive findings that cannot be verified by an alternative method are interpreted as lacking clinical significance. In cases of overlapping PBC/autoimmune hepatitis (AIH), AIH markers can occur simultaneously with AMA-M2.
  • M2-3E (BPO) is a recombinant fusion protein composed of various subunits of the mitochondrial antigen M2. Antibodies against mitochondria (AMA) type M2 are markers for manifest or future development of primary biliary cholangitis (PBC) and occur in just over 90% of the cases. In PBC, a strongly positive reaction for AMA-M2 is usually detected. Weakly positive findings that cannot be verified by an alternative method are interpreted as lacking clinical significance. In overlapping PBC/autoimmune hepatitis (AIH), AIH markers may occur simultaneously with AMA-M2.
  • Antibodies against Sp100 are a strong marker for PBC (primary biliary cholangitis) and can occur with or without the simultaneous presence of AMA-M2.
  • Antibodies against PML can in rare cases be seen in PBC (primary biliary cholangitis) but rarely occur in isolation.
  • Antibodies against gp210 are a strong marker for PBC (primary biliary cholangitis) and are associated with a more aggressive disease course.
  • Antibodies against LKM-1 are a marker for autoimmune hepatitis (AIH).
  • Antibodies against LC-1 most often occur together with LKM-1 antibodies and are a marker for autoimmune hepatitis (AIH). Isolated occurrence of anti-LC1 occurs in about 10% of the cases. The value of a weakly positive reaction is uncertain. Strongly positive anti-LC1 is associated with a more severe disease course. Anti-LC-1 has in rare cases been reported in hepatitis C.
  • Antibodies to SLA/LP are a strong marker for autoimmune hepatitis (AIH) and are present in approximately 10% of the cases. Anti-SLA is associated with a more severe course of the disease and can occur without ANA and/or smooth muscle antibodies being detected.
  • Anti-SSA/Ro52 is associated with several different autoimmune conditions such as autoimmune liver disease, anti-synthetase syndrome and other inflammatory systemic diseases.
