Is a TSH of 1.27 normal?
The normal range of TSH levels in adults is between 0.4 to 4.0 mIU/L (milli-international units per liter). Some research suggests that this range should actually be more like 0.45 to 2.5 mIU/L. The TSH range may also vary slightly based on the testing facility where your blood is being analyzed.

What should your TSH level be with no thyroid?
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 does low TSH mean with no thyroid?
High TSH levels can mean your thyroid is not making enough thyroid hormones, a condition called hypothyroidism. Low TSH levels can mean your thyroid is making too much of the hormones, a condition called hyperthyroidism. A TSH test does not explain why TSH levels are too high or too low.
Is 1.5 A low TSH level?
This is based on research that within a healthy population, the average TSH is approximately 1.5 mIU/L, and that a TSH greater than 2.5 or 3 mIU/L may be suggestive of thyroid dysfunction (1) (2).
Is TSH 1.3 Low?
A normal range for TSH in most laboratories is 0.4 milliunits per liter (mU/L) to 4.0 mU/L. If your TSH is higher than 4.0 mU/L on repeat tests, you probably have hypothyroidism.
What does TSH do after thyroidectomy?
Suppression of thyroid-stimulating hormone (TSH) after thyroidectomy for low-risk cancer can increase the risk of osteoporosis in women without cutting back on cancer recurrence, according to some reports. TSH suppression was defined as a median level of 0.4 mU/L or less.
What causes low TSH after thyroidectomy?
Causes: (1) Iodine deficiency, (2) Iatrogenic – after thyroidectomy, radioactive iodine treatment, radiation exposure to head and neck, and/or certain medications.
Does TSH matter after thyroidectomy?
Why is TSH kept low after thyroidectomy?
After thyroidectomy for well-differentiated thyroid cancer, TSH is often suppressed because it stimulates thyroid cell proliferation, and a goal of treatment is to inhibit the growth of residual neoplastic tissue.
What levels should be checked after thyroidectomy?
A previously normal TSH level should be rechecked at least biannually in an asymptomatic patient post-thyroid lobectomy or total thyroidectomy.
Is having no thyroid a disability?
