Soluble Liver Antigen Antibody, IgG
Also known as: SLA
Use
Recommended for the evaluation of autoimmune liver disease or hepatitis of unknown etiology. The presence of SLA antibodies has almost 100% specificity for autoimmune hepatitis, although only 12-30% have these antibodies. Thus, a negative SLA IgG test does not rule out autoimmune hepatitis.
