To diagnose hyperthyroidism, doctors usually ask patients to undergo a series of laboratory tests. The following are topics related to hyperthyroidism that have been hotly discussed on the Internet in the past 10 days and detailed analysis of laboratory items.
1. Hot Topics of Hyperthyroidism
Recently, topics related to hyperthyroidism have triggered extensive discussions on social media and health forums, mainly focusing on the following aspects:
| hot topics | focus of discussion |
|---|---|
| Early symptoms of hyperthyroidism | Palpitation, hand tremors, weight loss, etc. |

2. What tests are needed for hyperthyroidism?
Diagnosing hyperthyroidism requires blood tests to assess thyroid function. The following are common laboratory items and their clinical significance:
| Laboratory items | English abbreviation | normal reference value | clinical significance |
|---|---|---|---|
| thyroid stimulating hormone | TSH | 0.27-4.2 mIU/L | Usually lower in hyperthyroidism |
| free thyroxine | FT4 | 12-22 pmol/L | Usually elevated in hyperthyroidism |
| free triiodothyronine | FT3 | 3.1-6.8 pmol/L | Usually elevated in hyperthyroidism |
| thyroid peroxidase antibodies | TPOAb | <34 IU/mL | Evaluate for autoimmune thyroid disease |
| thyroglobulin antibodies | TgAb | <115 IU/mL | Evaluate for autoimmune thyroid disease |
| thyroid stimulating hormone receptor antibodies | TRAb | <1.75 IU/L | Important indicators for diagnosing Graves' disease |
3. Precautions for hyperthyroidism test
1.Preparation before inspection:Most thyroid function tests do not require fasting, but some hospitals may require fasting blood collection. It is recommended to consult a doctor in advance.
2.Drug effects:Certain drugs such as thyroid hormone preparations and iodine-containing drugs will affect the test results, so the doctor needs to be informed of the medication in advance.

In addition to blood tests, your doctor may recommend the following tests:
| Check items | Inspection purpose |
|---|---|
| Thyroid ultrasound | Assess thyroid size, shape, and blood flow |
| Thyroid radionuclide scan | Differentiating Graves' disease from thyroiditis |
| electrocardiogram | Assessing the effects of hyperthyroidism on the heart |
5. Treatment and follow-up of hyperthyroidism
After hyperthyroidism is diagnosed, doctors will develop a personalized treatment plan based on the cause and severity of the condition. Common treatments include:
1.Medication:Use of antithyroid drugs such as methimazole or propylthiouracil requires regular monitoring of liver function and white blood cell counts.
2.Radioactive iodine treatment:It is suitable for patients who are ineffective or relapsed after drug treatment. Hypothyroidism may occur after treatment.
3.Surgical treatment:It is suitable for patients with obvious goiter or suspected malignant transformation, who need lifelong thyroid hormone supplementation after surgery.
No matter which treatment is taken, regular rechecks of thyroid function are crucial. With standardized laboratory examinations and treatment, most patients with hyperthyroidism can have a good prognosis.
