Thyroid Stimulating Hormone

What Does This Test Check?

This test measures thyroid stimulating hormone (TSH), the signal the brain sends to the thyroid gland. It is the standard first check for thyroid health, because the level rises when the gland is underactive and falls when it is overactive.

Lola Health offers the Thyroid Stimulating Hormone test at £12, with results in one to four working days from a home sample. It is the sole option on this page, so there is no price comparison to make.

An abnormal TSH may indicate a thyroid problem, but levels wobble with illness, sleep and medication timing, and one reading does not diagnose a condition. GPs usually repeat the test and add T4 before drawing conclusions, so take the result to your doctor for interpretation.
