ANTI MICROSOMAL ANTIBODY (AMA)

The anti-microsomal antibody (AMA) test detects the presence of autoantibodies against microsomal antigens, which are associated with autoimmune thyroid diseases such as Hashimoto’s thyroiditis and Graves’ disease. AMAs target thyroid peroxidase (TPO), an enzyme crucial for thyroid hormone production. A positive AMA test indicates an immune response against the thyroid gland, leading to inflammation and impaired thyroid function. This test is essential for diagnosing autoimmune thyroid disorders, guiding treatment decisions, and monitoring disease progression. It helps identify individuals at risk of developing thyroid dysfunction and ensures appropriate medical management.
