FYI
I knew about TSH (thyroid) but wasn't aware of false low proBNP (marker used to diagnose heart failure). Biotin interferes with the lab tests because of the method of testing. It does not affect the disease unless a doc erroneously mistreats based on the false lab results...so just be sure to tell them you if you take biotin.
Sorry tried to copy/paste article and it won't work today???
