The Anti-TPO Microwell ELISA kit is part of Biomerica's line of microwell autoimmune products. High levels of TPO autoantibodies are found in a high percentage of patients with Hashimoto's disease (hyperthyroid) and lymphadenoid goiter (euthyroid) cases. Low TPO autoantibodies may be significant in pediatric Hashimoto's disease. The BIOMERICA Anti-TPO ELISA kit is particularly effective in helping to diagnose these conditions.
