About this test
TSH alone is usually enough to tell whether the thyroid needs investigating further. It rises when the thyroid is underactive and falls when it is overactive, often before the thyroid hormones themselves move outside the normal range.
What it measures
- Thyroid stimulating hormone
A note on results. A single test is one part of a clinical picture, not a diagnosis. Discuss your report with a qualified doctor, who will read it alongside your history and examination.
