Tg ABS refers to Thyroglobulin antibodies.
Understanding Thyroglobulin Antibodies (TgAb)
Thyroglobulin (Tg) is a protein made by the thyroid gland. The immune system typically doesn't produce many antibodies against thyroglobulin since it is not a germ. However, in some cases, the body may develop thyroglobulin antibodies (TgAb).
What are Antibodies?
- Antibodies, also known as immunoglobulins, are proteins produced by the immune system.
- Their main function is to recognize and neutralize harmful substances like bacteria, viruses, and other foreign bodies.
- Typically, the body doesn't create many antibodies against its own proteins.
Why are TgAb Created?
- TgAb are antibodies that specifically target thyroglobulin.
- The immune system may mistakenly identify thyroglobulin as a harmful substance and produce antibodies against it.
- The presence of TgAb can indicate autoimmune thyroid disease or other thyroid conditions.
Relevance of TgAb
- TgAb levels are often checked in individuals with thyroid disorders.
- Elevated TgAb levels can help in the diagnosis and management of autoimmune thyroid diseases like Hashimoto's thyroiditis.
How TgAb Results are Used
- TgAb results are used along with other diagnostic tools to help understand thyroid function and conditions.
- These results can help guide treatment decisions.
