Can Biotin Affect Blood Work?

What blood tests does biotin interfere with? Most of the published research on biotin interference covers hormone tests, such as parathyroid hormone (PTH), thyroid stimulating hormone (TSH), T4 and T3 tests, as well as tests for troponin.

When should I stop taking biotin before a blood test? 8 hours

Can biotin affect your TSH levels? Most commonly, biotin use can result in falsely high levels of T4 and T3 and falsely low levels of TSH, leading to either a wrong diagnosis of hyperthyroidism or that the thyroid hormone dose is too high.
