Is a thyroid-stimulating hormone (TSH) level of 2.32 normal?

　　A TSH (thyroid-stimulating hormone) level of 2.32 is within the normal range. TSH is a hormone secreted by the anterior pituitary gland. Due to variations in reagents, instruments, and assay methods among different hospitals, reference ranges may differ. Generally, for adults aged 18 years and older, the normal TSH range is 0.55–4.78 µIU/mL; for children aged 2–12 years, the normal range is 0.64–6.27 µIU/mL. Thus, a TSH level of 2.32 falls well within the normal range.

　　Elevated TSH levels are commonly associated with hypothyroidism or pituitary disorders.

　　Conversely, decreased TSH levels typically indicate hyperthyroidism.

　　However, whether TSH is elevated or reduced, this single value alone cannot be used to diagnose disease. A comprehensive clinical assessment—including symptoms, physical findings, and results of auxiliary tests—must be performed by a qualified physician to determine the underlying condition.
