Methodology:	Enzyme Immunoassay (EIA)
Testing Schedule:	Routine, 1 time per week
Report Available:	3-10 days
Special Instructions and/or Comments:
Refrigerate
Reference Range:
<20.1 Units
Clinical Utility:
SLA or “Cytokeratin” Autoantibodies are associated with autoimmune hepatitis (AIH), type 2. AIH patients are generally divided into 2 groups based on the presence of specific autoantibodies.AIH type 1 is the more common type of AIH, and is characterized by Antinuclear Antibodies (ANA), Smooth Muscle Autoantibodies (ASMA), and the “perinuclear type” of ANCA. AIH type 2 is characterized by auto antibodies directed against soluble liver antigen (SLA) and liver cytosol antigen (LC-1) - AIH type 1 patients are characteristically negative for SLA and LC-1autoantibodies. Although only about 12-30% of AIH patients have SLA autoantibodies, the presence of these has almost 100% specificity for AIH.

Strongyloides stercoralis is a parasitic nematode found in tropical and subtropical regions. Because of low larval densities in feces, stool examination is a relatively insensitive diagnostic test; serodiagnosis by ELISA offers increased sensitivity. Antibody titers decrease in many patients following treatment. Patients with latent infections, who are immunosuppressed or receiving immunosuppressive therapy, are at risk of life-threatening hyperinfection.
