What it measures
TSH is made by the pituitary gland and signals the thyroid to produce thyroid hormones.
Why it may be considered
A clinician may use it when investigating thyroid function, often alongside other thyroid tests.
What affects interpretation
TSH alone does not establish the cause of a thyroid problem. Medicines, supplements, pregnancy, and your other thyroid results matter. Tell your clinician about everything you take.
Laboratory reference ranges depend on the test and laboratory. This glossary does not interpret your results or imply that Lola orders this test. Your provider will determine what is relevant to your care.
Questions to bring
- Why is this test relevant to my situation?
- Do I need to prepare or time the sample?
- How does this result fit with my symptoms and other findings?
