What is the normal TSH level for an average male?

What is the normal TSH level for an average male?

Depends: On who you ask. Most lab reports show normal as being 0.5 - 5 mlu/l, but many people feel the range should be 0.3 - 3. If you are being treated for hypothyroidism, the ideal range is 1 -2. I usually start to take notice when someone's TSH is >2.5. See http://www.Nlm.Nih.Gov/medlineplus/ency/article/003684.Htm. ...Read more

Thyroid blood test: normal tsh, and normal t 4, slightly lower free t3 (liothyronine). What is a normal TSH level?

Thyroid blood test: normal tsh, and normal t 4, slightly lower free t3 (liothyronine). What is a normal TSH level?

Free T3 (liothyronine) levels are not accurate in many labs, so a slightly low level may be meaningless. You should see an endocrinologist if you have symptoms. ...Read more
