How often should TSH be checked?
A TSH blood test should be obtained at least every 6-12 months while you are on a stable thyroxine dose, and more often if your dose is changed. Your doctor will usually wait 6-8 weeks after a thyroxine dose adjustment to measure your TSH, when the levels of thyroxine have reached a steady state.
How much should your thyroid fluctuate?
The typical range of reference for TSH levels is anywhere between 0.45 and 4.5 milliunits per liter (mU/L) . A recent study suggests that the normal range should be more like 0.45 to 4.12 mU/L. TSH can vary wildly based on your age, sex, and stage of life.
