NCT ID NCT07302880
First seen Jan 05, 2026 · Last updated May 22, 2026 · Updated 24 times
Summary
This study looks at how taking a high dose of biotin (vitamin B7) can temporarily mess up certain blood tests. Researchers will give 24 healthy adults either biotin or a placebo and then check their blood for changes, especially in thyroid antibody levels. The goal is to understand when the interference is strongest and how long it lasts, helping doctors and patients get accurate lab results.
