What Tsh Level Is Considered To Be A Sign Of Hypothyroidism
It's controversial: There is broad consensus that a TSH between 0.3-2.5 is normal (assuming no pituitary problem exists), and broad consensus that TSH levels above 10 are abnormal and should be treated. A middle-of-the-road approach might be to say that levels between 5-10 are abnormal, and treatment is likely to be beneficial, and that values between 2.5-5 may be abnormal, and that treatment may be beneficial. ...Read moreSee 1 more doctor answer
More than 2mg/dl: This number has to be carefully interpreted in the context of other liver tests, clinical context and medical history. ...Read more
Could a low TSH but normal Free T4 mean a Pituitary problem? Or would that be more indicative of the start of Hypothyroidism?
Sounds normal: Your description is consistent with normal thyroid function, but if you are concerned, you could provide exact numbers for us to review. ...Read more
Hashimotos: The most common cause is hashimotos thyroiditis, which is an autoimmune slow destruction of the thyroid. It tends to run in families, but not perfectly. It is easy to fix with thyroid replacement. ...Read more
Tsh level is a 3 which is causing pharmacist to be concerned. I do have many symptoms of hypothyroidism, what tests should be done?
Normal TSH 0.45-4.5: Why is your pharmacist concerned? Tsh of 3 is normal. Of course, we're trained to treat the person, not just the numbers so many of us will prescribe enough medication to achieve TSH of 1-2. Tsh less than 0.45 increases risk for hyperthyroidism eg palpitations, tremors, anxiety, insomnia, bone loss, etc. Further testing depends upon your symptoms. Bottom line: talk to your doc who ordered test. ...Read more
What would cause a low T3 (liothyronine) level but normal TSH and T4 levels? Would that be considered hypothyroidism?
No: Low t3 (liothyronine) with nl TSH and T4 is not hypothyroidism. Many things can make t3 (liothyronine) levels decrease such as illness, stress, colds etc. It is nonspecific and could also be lab error so low t3 (liothyronine) in the face of nl TSH and free T4 levels does not mean very much. ...Read moreSee 1 more doctor answer
Very unlikely: A very overactive thyroid is virtually always associated with a very low or undetectable tsh. Of course a laboratory error could be responsible and the test should always be repeated if it does not fit with the clinical picture. Lastly, stress and/or an underactive adrenal gland can sometime mimic and overactive thyroid. ...Read moreSee 1 more doctor answer
What is the upper high limit of TSH at which point clinical hypothyroidism should be considered? My. Dr refuses to believe I could be. 1yr+
Hypothyroidism: The upper limit of TSH is about 4, but it varies from lab to lab. Presumably you have symptoms that could be from subclinical hypothyroidism, but it is possible that these symptoms are from something else. If your TSH were consistently high, and you had symptoms, I would probably begin levothyroxine treatment, esp if there were other signs of thyroid failure (anti-TPO ab, goiter, family history) ...Read moreSee 1 more doctor answer
Lab dependent: Each lab has slightly different reference ranges for each test. If you are asking about the TSH test, usually range is 0.4-4.0. Borderline high (for me) is 4.0-8.0, and above 8.0, i usually will treat or adjust the patients thyroid replacement. ...Read more
What could be the cause of a ferritin level to suddenly be greater than the clinically reportable range and is this dangerous?
Normal range: Serum TSH level ranges from 1.0 to 38.9 miu/l for term newborn. ...Read more
Thyroprotein/tsh level- what number is indicative of hypothyroidism? My results says 3 and normal range is 2-8. Is there another test to determine thyroid issues related to CHF? Also, is H.pylori count of 2 means positive for it? On protonixThanks.
ThryoTROPIN: is a synonym for thyroid stimulating hormone (TSH). This hormone, produced by the pituitary gland, regulates thyroid function. Normal results for adults, in most labs, are 0.4-4.2 mU/L. This is the well-recognized/accurate test for hypothyroidism; a total thyroxine can sometimes add information.An H. pylori antibody blood test only measures past infection. Biopsy, stool antigen, breath test better ...Read moreSee 1 more doctor answer
