Can taking biotin affect blood tests? Biotin in blood or other samples taken from patients who are ingesting high levels of biotin in dietary supplements can cause clinically significant incorrect lab test results.
What lab tests does biotin affect? 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. However, because biotin is used in so many immunoassays, scientists say it could interfere with many others.
How much biotin interfere with lab tests? Individuals who regularly take more than 5,000 mcg of biotin per day may have an excess amount in their blood, which can interfere with some types of laboratory tests called immunoassays. This is because some immunoassays use biotin as part of the reagent mixture in the testing method.
