Blood samples aim to harmonize thyroid testing worldwide
NCT ID NCT05151120
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study collected extra blood samples from 28 adults with thyroid disorders to help standardize thyroid-stimulating hormone (TSH) tests. Different labs often use different tests, making it hard to compare results. By analyzing these samples, researchers hope to make TSH measurements more consistent, which could improve diagnosis and care for thyroid patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help make thyroid test results more comparable between different laboratories, improving diagnosis and monitoring for patients.
- What could go wrong
- This is a small, completed sample-collection study, not a treatment trial. It aims to improve lab tests, not directly help participants.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Male or female ≥ 18 years of age * Body weight ≥ 62 kg * With a thyroid disorder (with high, low or normal TSH levels) * Competent to give non opposition after information Exclusion Criteria: * Age \<18 years old * Those individuals previously enrolled into this clinical study * Individuals diagnosed with a severe non-thyroidal illness at physician's appreciation. Defined as a state of dysregulation where levels of T3, T4, free triiodothyronine (FT3) and/or free thyroxine (FT4) are abnormal although the Thyroid gland does not appear to be dysfunctional. In practice, non-thyroidal illness (NTI) is reported to be usually associated with critical illness or starvation. Examples: chronic renal failure, liver cirrhosis, advanced (active) malignancy, sepsis, trauma, prolonged fasting or starvation, heart failure, Myocardial infarction (MI), and any psychiatric disorder. * Pregnancy - please note that pregnancy test is not needed, a declaration is sufficient. The inclusion of a sample from a woman with an unidentified pregnancy will not jeopardize the study. * Patient under guardianship and under legal protection
