What is the normal range for thyroid levels?
Normal test range for an adult: 0.40 – 4.50 mIU/mL (milli-international units per liter of blood). T4: thyroxine tests for hypothyroidism and hyperthyroidism, and used to monitor treatment of thyroid disorders. Low T4 is seen with hypothyroidism, whereas high T4 levels may indicate hyperthyroidism.
What is the normal thyroid level in females?
TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.
What is considered a high level for thyroid?
Some suggest that TSH levels of over 2.5 milliunits per liter (mU/L) are abnormal, while others consider levels of TSH to be too high only after they have reached 4 to 5 mU/L. Both children and teenagers as well as older people have somewhat higher TSH levels than middle-aged people.
What is considered a low thyroid level?
