TSH Reference Ranges

by Leisa on August 15, 2008

Mary Shomon is a fantastic patient advocate for people with thyroid disorders, educating untold numbers of people through her books and her comprehensive website http://thyroid.about.com

Like myself and many others, Mary suffered from a thyroid condition that was incorrectly treated, and this led her on a journey to recover her health by finding out more about her thyroid and what the answer to healing might be.

On this journey she found that thyroid conditions were one of the most misunderstood and misdiagnosed conditions – leaving thousand of people suffering needlessly, often due to the rigid adherence by doctors to the standard protocol of TSH blood test results and Thryoxine prescriptions.

There has been much debate about the relevance and accuracy of the standard TSH test (thyroid stimulating hormone) and whether this test is a definitive diagnosis of a hypothyroid disorder.  There is a lot of literature to say that it is not – yet most doctors are not aware of the controversy surrounding this test and still use it as gospel.

If a patient has every hypothyroid symptom in the book, has a family history of thyroid disorder, has a low body temperature, and an enlarged thyroid (as I have seen in clinic) – but her TSH is in range, the doctor will more often than not refuse to treat the patient for a thyroid condition.

The patient will be prescribed anti-depressants, told to eat less and exercise more for the weight gain, and that the fatigue is just a natural part of getting older.

None of this actually helps the patient, who continues to decline in health until a forward thinking practitioner uses their judgement and treats the thyroid.

Many patients ask me what literature they can take to their doctor to help them to understand that the TSH test can be misleading, and a result that is at the high end of the range can indicate a hypothyroid problem.

In  Mary Shomon’s latest post she give links to articles discussing the health issues of sub-clinical hypothyroidism (normal TSH but thyroid symptoms) citing scientific journals to illustrate their point.

If you think your doctor might be willing to read about this issue, then this would be a good place to start:
