Description

A thyroid scan helps diagnose nodules, goiter, or function disorders like hyperthyroidism; patients in China may need it after abnormal blood tests or neck symptoms, with costs typically 70–150 USD (500–1000 CNY), and ChinaMedicalHub assists with hospital booking and interpreter support.

Main Uses

Thyroid scans are primarily used to evaluate the structure and function of the thyroid gland. They help in diagnosing hyperthyroidism or hypothyroidism, identifying the presence and nature of thyroid nodules (hot or cold), and differentiating between benign and malignant thyroid conditions. Additionally, they are useful in planning treatment strategies such as surgery or radioactive iodine therapy.

Normal Range

The normal range for a thyroid scan typically involves assessing the uptake of radioactive iodine or technetium by the thyroid gland. A common indicator is the percentage of radioactivity uptake, which usually falls between 8-35% at 24 hours post-administration. The distribution should be even across both lobes without any hot or cold nodules.

Low Values - Possible Causes

Hypothyroidism, iodine deficiency, recent use of iodine-containing medications, non-thyroidal illness (sick euthyroid syndrome), and certain autoimmune diseases like Hashimoto's thyroiditis
