How many mcg daily dose of biotin interferes with thyroid tests? my daily multivitamins has 75 mcg(250% of daily value) in it. should i stop taking it before thyroid test?
A doctor has provided 1 answer
No, the biotin content in MVI does not interfere with thyroid function test. Dose of 5,000 mcg or more may cause spurious results in thyroid test assays using biotin-streptavidin affinity systems in their design.
