Introduction
Subacute thyroiditis, also known as subacute thyroid inflammation, should be evaluated with thyroid function tests, blood chemistry tests, thyroid color Doppler ultrasound, and cytological examination. Different patients should undergo the most appropriate diagnostic methods based on their specific conditions, selecting the most suitable tests to facilitate accurate diagnosis and effective treatment.

Generally, "subacute thyroiditis" refers to subacute thyroiditis. For subacute thyroiditis, three main tests are recommended: thyroid function tests, blood chemistry tests, and thyroid color ultrasound (color Doppler ultrasound). The details are as follows:

1. Thyroid Function Tests

These include three indicators: thyroid-stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). Abnormal thyroid function is one of the common causes of thyroid disorders. Therefore, thyroid function testing helps doctors assess the severity of the disease and determine an appropriate treatment plan.

2. Blood Chemistry Tests

These primarily include complete blood count (CBC), liver function tests, and kidney function tests. A CBC can reveal whether the patient has anemia and whether white blood cell and platelet counts are within normal ranges. Liver and kidney function tests help detect abnormalities in hepatic or renal function, as well as possible drug allergies. These tests assist doctors in evaluating the patient's condition and response to treatment, allowing timely adjustments to the treatment plan.

3. Thyroid Color Ultrasound

This imaging test can identify the presence of thyroid masses or nodules, helping doctors evaluate disease severity and monitor treatment effectiveness. Additionally, thyroid antibody testing may be performed to determine whether an autoimmune disorder is present, which further guides the selection of appropriate therapy.

Besides the above, fine-needle aspiration cytology (FNAC) is another important diagnostic method, involving extracting thyroid cells via needle biopsy for laboratory analysis. Different patients should select the most suitable diagnostic methods based on their individual conditions to ensure accurate diagnosis and effective treatment. If test results are abnormal, prompt medical attention and treatment are essential.
