Thyroid Tests: How Can They Uncover Hidden Hyperthyroidism?
Published: Oct 19, 2023
Thyroid tests are vital tools in diagnosing hyperthyroidism and understanding its root cause.
Radioiodine Uptake Test: A Key Diagnostic Tool
The radioiodine uptake test measures how much iodine your thyroid absorbs. A high uptake indicates active hormone production, often seen in disorders like Graves' disease. A low uptake can suggest inflammation or external hormone sources.
Blood Tests: Checking Hormone Levels
Blood tests measure levels of thyroid hormones and thyroid-stimulating hormone (TSH). High thyroid hormone and low TSH levels typically suggest hyperthyroidism. These tests are crucial for confirming the diagnosis and guiding treatment.
