The latest controversy dates back to the Fall of 2002, when the American Association of Clinical Endocrinologists (AACE), a key professional society in the thyroid field, announced that as far as the Thyroid Stimulating Hormone (TSH) test—the so-called “gold standard” test for thyroid diagnosis—what was normal the year before was no longer normal.

According to the AACE, doctors had typically been basing their thyroid diagnoses on the reference range for the TSH test.

Losing weight while pregnant if overweight After decades of denying that patients within the normal range of TSH could in fact have a thyroid condition, they were acknowledging what patients and advocates had been saying quite vocally for years: that the high and low end of the normal range is not, in fact, normal for many people.

Unfortunately, what was considered a very positive development for thyroid patients did not make a significant impact, for several reasons:

• Laboratories never adopted the new range as the formal reference range, meaning that only levels outside the older, broader range were flagged as abnormal.

• The medical establishment continued to disagree about this, and eventually, the groups abandoned the recommendation to broaden the range, and continued to advocate for the current reference range.

For a brief moment, it seemed like the AACE and the endocrinology community had finally moved into the 21st century.
