First seen Nov 01, 2025 · Last updated Jun 16, 2026 · Updated 33 times
Summary
This study looks at whether measuring a different thyroid hormone (fT3) or the ratio of two hormones (fT3/fT4) can give a clearer picture of thyroid health in people taking levothyroxine. It includes 500 adults with various types of hypothyroidism who are on a stable dose of the medication. The goal is to improve lab tests for patients where the usual TSH test isn't reliable.
