MUSK ANTIBODY (MUSCLE SPECIFIC KINASE ANTIBODY)

The MuSK Antibody (Muscle Specific Kinase Antibody) test detects circulating anti‑MuSK IgG antibodies in serum, using sensitive immunoassay methods to identify an autoimmune target associated with a subset of myasthenia gravis (MG). Detection of MuSK antibodies helps distinguish MuSK-positive MG from AChR-positive or seronegative forms, which is important because MuSK-associated disease often presents with prominent bulbar and respiratory involvement and may respond differently to therapies.

This home collection service in Dubai provides convenient venous blood sampling at your residence with results processed in accredited UAE laboratories and accompanied by interpretive comments for your physician. The test is recommended when clinical signs suggest MG—especially ptosis, diplopia, fluctuating fatigable weakness, or prominent bulbar symptoms—or when AChR antibody tests are negative; results support diagnosis, treatment planning, and specialist referral to neurology in the UAE healthcare system.
