Gastric parietal cell (GPC) antibodies are associated with autoimmune conditions affecting the stomach lining, such as autoimmune gastritis. These may impact vitamin B12 absorption and digestive health.

Liver kidney microsomal (LKM) antibodies are associated with certain types of autoimmune hepatitis. Their presence may indicate an autoimmune process affecting liver cells.

Smooth muscle antibodies (SMA) are often found in autoimmune liver conditions, including autoimmune hepatitis. Elevated levels may indicate an immune response targeting liver tissue.

Anti-mitochondrial antibodies (AMA) are associated with autoimmune liver conditions, particularly primary biliary cholangitis (PBC). The presence of AMA may indicate an autoimmune response affecting the liver.

ESR is a blood test that can indicate inflammation and is often used in autoimmune disease assessment.

CRP is a marker of inflammation that may be elevated in autoimmune and inflammatory conditions.

ANA tests detect antibodies that may attack the body’s own tissues and are commonly used to screen for autoimmune diseases.
