Thyroid cytology: It is a pathologic test that is helpful in clarifying whether thyroid lesions are benign or malignant.

Thyroid gene test: It is a laboratory testing technique that performs gene test on tissues, blood, saliva and cells. This test helps to know whether there is a gene mutation in thyroid cancer, which has a certain role in the choice of treatment plan for thyroid cancer. Patients with thyroid disease should choose the appropriate test under the guidance of their doctors to clarify their condition and actively treat it.
