A thyroid test result is easier to understand when someone explains what was measured and why. If symptoms are continuing, it is reasonable to ask your GP to review the result with you and discuss the next step.
What is usually tested?
Thyroid-stimulating hormone, or TSH, is usually checked first. Depending on the result and your circumstances, your doctor may request thyroid hormones T4 and T3 or other investigations. More tests are not automatically needed for every person. Healthdirect — Thyroid function tests.
The thyroid makes hormones involved in how your body uses energy. Both too much and too little thyroid hormone can affect how you feel. Healthdirect — Thyroid gland.
Make your results useful
Ask for an explanation in everyday language:
- Which test was ordered, and what question was it intended to answer?
- How does this result fit with my symptoms?
- Do we need to repeat a test or investigate something else?
- When should I arrange a follow-up appointment?
Tell your doctor about medicines and supplements you take, including any products marketed for thyroid support. Follow the preparation instructions given by your doctor or collection centre. Healthdirect — Thyroid function tests.
Keep looking at the whole picture
A result deserves interpretation in context. If your symptoms persist, discuss them again rather than interpreting a number in isolation. Your doctor can explain what the findings mean for you and whether further assessment is needed. Healthdirect — Thyroid function tests.
Bring previous results if you have them, along with a brief account of what has changed. Our introduction to the thyroid explains the basic terms you may hear.
