1. Main departments for hyperthyroidism examination
The examination of hyperthyroidism usually involves the following departments:
| Department | Check content | Remarks |
|---|---|---|
| Endocrinology | Thyroid function test (T3, T4, TSH, etc.) | Preferred department responsible for diagnosis and treatment |
| General Surgery | Thyroid ultrasound, needle biopsy | When thyroid nodules or tumors are suspected |
| Department of Nuclear Medicine | radioactive iodine uptake test | Assess thyroid function status |
| Cardiovascular Medicine | EKG, cardiac ultrasound | Hyperthyroidism combined with heart disease |
2. Common examination items for hyperthyroidism
The diagnosis of hyperthyroidism requires a combination of clinical symptoms and laboratory tests. The following are common test items:
| Check items | normal reference value | clinical significance |
|---|---|---|
| Free T3 (FT3) | 3.1-6.8 pmol/L | Elevated levels suggest hyperthyroidism |
| Free T4 (FT4) | 12-22 pmol/L | Elevated levels suggest hyperthyroidism |
| Thyroid Stimulating Hormone (TSH) | 0.27-4.2 mIU/L | Reduced levels suggest hyperthyroidism |
| Thyroid antibodies (TPOAb, TGAb) | negative | Positive indicates autoimmune thyroid disease |
| Thyroid ultrasound | - | Assess thyroid morphology and blood flow |
3. Examination process for hyperthyroidism
1.first diagnosis: When patients experience symptoms such as palpitation, hand tremors, and weight loss, they can first go to the endocrinology department for treatment.
2.laboratory tests: The doctor will prescribe thyroid function tests (FT3, FT4, TSH) and antibody testing.
3.Imaging examination: Depending on the condition, thyroid ultrasound or radioactive iodine uptake test may be performed.
4.multidisciplinary consultation: If it is combined with other systemic diseases (such as heart disease), it needs to be jointly diagnosed and treated with cardiovascular medicine and other departments.
