Thyroglobulin Antibodies (TgAb) are antibodies that can be present in autoimmune thyroid conditions such as Hashimoto’s thyroiditis. The presence of TgAb can help diagnose these conditions.

iollo markers that associate with Thyroglobulin Antibodies (TgAb)

​
Phenylalanine

Phenylalanine is another amino acid component of thyroglobulin. Abnormal phenylalanine levels could indicate impaired thyroglobulin synthesis or degradation related to TgAb.

Tyrosine

Tyrosine is a key component of thyroglobulin, the protein targeted by TgAb in autoimmune thyroid disorders like Hashimoto’s thyroiditis. Altered tyrosine levels may reflect disrupted thyroglobulin metabolism.
