An age-specific range may be useful Some people believe that the upper limit should be lowered to 2.5 mIU/L. They believe that if you take groups of patients and exclude all of the people with any ...

Medically reviewed by Danielle Weiss, MD Your thyroid-stimulating hormone (TSH) levels are important for many bodily functions, like your metabolism, weight management, body temperature regulation ...

The study aimed to investigate the association between serum TSH within the reference range and blood pressure through a 5-year follow-up study.

An accurate TSH reference range is important for pregnant women, as those with a dysfunctional thyroid can put them at higher risk for high blood pressure, miscarriage and a baby with a low ...

Polygenic score is a stronger predictor for thyroid-stimulating hormone levels than free thyroxine and other factors, and could be used to develop individual TSH reference ranges for adults ...

BACKGROUND: Prescribing of levothyroxine and rates of thyroid function testing may be sensitive to minor changes in the upper limit of the reference range for thyroid-stimulating hormone (TSH) that ...

For the elderly, the healthy reference range may be higher than the adult range - having a TSH of 5.6 mlU/L may still be healthy, he said.

Normal reference ranges of blood levels of thyroid-stimulating hormone and free thyroxine may not be suitable to determine thyroid function in patients with various types of cancer.

"Because the [population-based, laboratory] reference ranges don't account for seasonal variation, we're flagging a significant number of people as high TSH when they're normal, and physicians are ...

When the subjects were grouped according to TSH levels (<0.20 mIU/l, quartiles within the reference range 0.20–4.00 mIU/l and >4.00 mIU/l) there was no linear relation between serum TSH level ...

Meamar et al. (2021) discussed the push of physicians and the National Health and Nutrition Examination Survey to reduce the TSH reference range to .4 -2.5 mU/L.
