Anti Soluble Liver Antigen; SLA

ANTI SOLUBLE LIVER ANTIGEN; SLA Test Purpose

The Anti Soluble Liver Antigen (SLA) Test is performed to detect antibodies against soluble liver antigen (SLA) in the blood. Primarily, the test is used to help diagnose Autoimmune Hepatitis (AIH), particularly in individuals with suspected disease but negative results for other autoimmune liver antibodies. Additionally, it assists healthcare providers in confirming the diagnosis of autoimmune hepatitis and differentiating it from other liver disorders, such as viral hepatitis, alcoholic liver disease, and non-alcoholic fatty liver disease. Furthermore, Anti-SLA antibodies are considered highly specific for autoimmune hepatitis and may be associated with a more severe disease course in some patients.
