What is TSH and when should I test?Updated a year ago

Thyroid-stimulating hormone (TSH) is the most sensitive marker of thyroid function, making it the biomarker to measure to assess thyroid function 

TSH regulates metabolic functions like lipogenesis and lipolysis, the creation and breakdown of fats for energy, and energy storage and expenditure.
