What is the difference between TSH and TSH reflex?

The TSH reflex (TSH reflex or TSH-r) is the diagnostic protocol through which the blood dosage is measured. If the reflex TSH is #low, i.e. lower than 0.5 mIU / l, thyroxine (T4) in its free fT4 form is also dosed, and then, if this falls within normal values, also triiodothyronine (T3).

Values ​​higher or lower than the reference ones highlight acute or chronic thyroid pathologies. If the TSH level is higher, it could indicate hypothyroidism. If it is lower, the initial diagnosis may be hyperthyroidism.

What does it mean when the TSH is low?

A reduced TSH, on the other hand, indicates an excess of thyroid hormones (hyperthyroidism). This can happen in diseases in which the thyroid gland works too much or it can indicate that the amount of thyroid hormone that the patient is already taking for hypothyroidism is excessive and must be reduced.

What are the blood values ​​for the thyroid gland?

Values ​​in the norm of TSH in the blood range from 0.5 to 5 microunits per milliliter of blood.
