Female taking high dose Biotin for progressive secondary MS presents with blood tests of thyrotoxiciosis. FT4 >7.8ng/ml N=0.9-1.7 and TSH <0.02 N=0.5-5.7.All the tests normalized after stopping the Biotin.
These tests can lead to unnecessary evaluation for the disease and even treatment with drugs, radiation or surgery.
