A previous PFPC comment focused on the fact that the NRC used TSH reference levels which were 4 years out of date. [Click here]

    What is perhaps even more astounding is the NRC’s complete failure to disclose/discuss that fluoride has been used in hundreds of laboratory investigations specifically as a thyroid-stimulating-hormone (TSH) analogue [=> acts like TSH].

    Instead, the NRC writes:
