Individual thyroid ranges are 38-68% the size of the lab reference range

We've known since at least 2002 that being within "normal range" is never good enough when it comes to thyroid hormone blood tests. An important set of articles has taught us that each human being has an optimal range for TSH, Total T4 and Total T3 that is far less the width of the population-wide …

Overreliance on TSH is a thyroid therapy policy that fails to detect its own failure

In standard T4 thyroid therapy, TSH normalization is so easy to achieve that it is almost impossible to fail. First, TSH out of range is the judge of an initial DIAGNOSIS. Next, normal TSH becomes the sole TARGET of therapy. Finally, normal TSH becomes the sole JUDGE of therapy success. This is faulty reasoning. There …

Targeting TSH? It’s not as specific or as sensitive as people claim.

Patients and doctors are often told there's an ideal "target" for TSH levels. Some believe that in thyroid therapy, your TSH should be below the upper reference limit, some say it should be below 2.5, and a minority will even say it should be suppressed entirely whether or not you are a thyroid cancer patient. …

What if TSH levels were like shoe sizes, thyroid meds like mobility aids

Seeing things visually might help clarify what thyroid therapy is like. Our thyroid hides in our neck and our hormones hide in every inch of our body. Nobody sees our thyroid gland distort, die, or shrivel. Nobody sees what fatigue feels like. Nobody sees organs suffering from lack of T3. Nobody sees how our pills …

Several fallacies in the TSH-T4 paradigm of thyroid therapy

When you are steeped in a medical paradigm, its fallacies can be as comfortable and taken for granted as an old pair of sneakers. In this post, I'll take apart several thyroid therapy fallacies, starting with the fallacy "description is not prescription." I will investigate many of the ways in which patients on T4 monotherapy …

The Abbott Free T3 test kit recall of 2018-2019

Recently I came across the information about the Free T3 lab test assay kit recall by Abbott Laboratories announced in late 2018. The recall was initiated in October 2018 and the FDA record was published in February 2019. The reason they list is the potential for a mistakenly lower Free T3 test result. "Samples tested …

How TSH ultrashort feedback works, and antibody interference

This post takes a closer look at the "ultrashort feedback loop," the biological mechanism by which the TSHR stimulating antibody (TSAb) can oversuppress TSH in any autoimmune hypothyroid patient. TSHR ANTIBODY EFFECTS ON MANY ORGANS As most people know, in Graves' disease, when TSH receptors on the thyroid gland are overstimulated by TSH-Receptor antibodies (TSAb), …
