What should my TSH level be to see a doctor?
What should my TSH level be to see a doctor?
For many years, most mainstream doctors have considered TSH level >10 mIU/L evidence of overt thyroid failure, and levels of 5-10 mIU/L evidence of mild or subclinical hypothyroidism. Many doctors refuse to treat hypothyroidism if a person’s TSH is less than 5 mIU/L even when the patient presents with classic hypothyroidism symptoms.
What was the normal TSH level for thyroid in 2002?
Until November 2002, doctors had relied on a normal TSH level ranging from 0.5 to 5.0 to diagnose and treat patients with a thyroid disorder who tested outside the boundaries of that range.
Is there an upper limit for serum TSH?
In future it is likely that the upper limit of the serum TSH reference range will be reduced to 2.5 mIU/L. In 2003, the American Association of Clinical Endocrinologists issued a press release in support of lowering the upper limit of the reference range: [5]
What are the effects of different TSH reference ranges?
A large body of evidence, which began to emerge in 2005, indicates that differences in thyroid function within the euthyroid TSH reference range are associated with negative health outcomes ( 22 ). Thyroid hormone plays an essential role in energy expenditure, lipid and glucose metabolism, and vascular integrity ( 1, 2 ).
