Synonyms

Additional Technical Information

Ordering Recommendations

Recommended for differential evaluation of neuromuscular junction diseases including myasthenia gravis (MG).

Reference Interval

Less than 1:40

Interpretive Data

When detected in the presence of acetylcholine receptor (AChR) antibody, striated muscle antibodies, which bind in a cross-striational pattern to skeletal and heart muscle tissue sections, are associated with late-onset myasthenia gravis (MG). Striated muscle antibodies recognize epitopes on three major muscle proteins, including: titin, ryanodine receptor (RyR) and Kv1.4 (an alpha subunit of voltage-gated potassium channel [VGKC]). Isolated cases of striated muscle antibodies may be seen in patients with certain autoimmune diseases, rheumatic fever, myocardial infarction, and following some cardiotomy procedures.

Saccharomyces cerevisiae IgG antibodies are found in 60-70% of Crohn disease (CD) patients and 10-15% of ulcerative colitis (UC) patients. Saccharomyces cerevisiae IgA antibodies are found in about 35% of CD patients but less than 1% in UC patients. Detection of both Saccharomyces IgG and IgA antibodies in the same serum specimen is highly specific for CD.
