 TSH Levels_Research
I read this and thought it may help some of you who are having trouble getting a DX based on 'normal' levels of TSH
More recently, researchers have looked at an important question: If the normal TSH range were narrowed, as has been recommended by AACE and the National Academy of Clinical Biochemistry, what are the implications?
One study found that using a TSH upper normal range of 5.0, approximately 5% of the population is hypothyroid.
However, if the upper portion of the normal range was lowered to 3.0, approximately 20% of the population would be hypothyroid.
Implications for Patients
It's now more than six years since the experts have established that this new, narrower TSH normal range of 0.3 to 3.0 is a more accurate one, and recommended that it become the standard of practice. Yet, the dithering continues. Some doctors use the new range for diagnosis and therapeutic management -- others refuse to consider anything unless it's marked "High" or "Low" on laboratory reports.
Patients can arm themselves with copies of the AACE and National Academy of Clinical Biochemistry reports, educate their practitioners, and patronize those doctors who stay up on the research, and leave behind those doctors who stick their heads in the sand and refuse to recognize millions of undiagnosed, undertreated people with hypothyroidism |
