[2] Another sign to help identify this disease is the presence of blocking anti-TSH receptors.

Ord's thyroiditis can share symptoms with functional hypothyroidism.

It is also characterized by invasion of the thyroid tissue by leukocytes, chiefly T-lymphocytes.

Transient hyperthyroid states in the acute phase, (a common observation in Hashimoto's thyroiditis), are rare in Ord's disease.

[citation needed] Ord's thyroiditis can be difficult to identify as its signs can be easy to miss or share symptoms with other diseases.
