Tests are ordered by an independent licensed physician. This service does not replace care from your own doctor. Talk with a healthcare professional about your results.
TSH (thyroid stimulating hormone) is made by the pituitary gland and tells your thyroid how much hormone to make. It is the test doctors most often use to screen for thyroid problems.
People order it when they feel tired, unusually cold or hot, notice weight or mood changes, or want to check how thyroid medicine is working.
Before your visit: no fasting is needed. If you take biotin supplements, ask your doctor whether to pause them first, since biotin can interfere with some thyroid tests.
