First seen Nov 01, 2025 · Last updated Jun 05, 2026 · Updated 32 times

Summary

This study looks at whether additional lab tests, like fT3 and the fT3/fT4 ratio, can better measure thyroid hormone status in people with hypothyroidism who take levothyroxine. Researchers will compare these tests in 500 patients and healthy controls. The goal is to improve diagnosis for patients where standard TSH tests are not reliable.
