What Are Tsh Levels For Hypothyroidism
Depends on lab: Hi. Normal ranges vary somewhat from lab to lab, but as a close approximation, TSH normal range is about 0.5 to 4.5 and free T4 normal range is about 0.8 to 1.8. If you get a copy of your lab results from your doctor, the normal ranges will be stated on the lab print out. Good luck! ...Read more
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 more
TSH over 30: But over 4 is abnormal alreadyGet a more detailed answer ›
Short-acting T3 (liothyronine): Cytomel (liothyronine) is the trade name for tri-iodothyronine, (t3). It is considered the active form of thyroid hormone, although all cells can convert T4 (the predominant product of the thyroid gland) into t3. Can be used to replace thyroid hormone, but it is short-lived. This means it must be taken multple times a day, and gives levels which are constantly going up and down (not ideal, hard to adjust). ...Read more
How are high levels of thyroid peroxidase antibody treated (125)tsh (317)ft4(74) is armour thyroid safe im ttc?
Likely: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, Most laboratories and endocrinologists use 5.0 as the limit, some use even a lower level to diagnose hypothyroidism. It would be prudent to follow your doctor's advice about medication. ...Read moreSee 1 more doctor answer
I have hypocretin deficient narcolepsy which reduces TSH levels along with autoimmune hypothyroidism. Is the TSH test reliable to gauge my thyroid?
Not always: TSH is not always a reliable test, because it relies on what the pituitary thinks, but different tissues may have different sensitivity to thyroid hormone. In addition, some people make too much reverse T3 (liothyronine), (liothyronine) which can block the action of T3 (liothyronine). Google "stop the thyroid madness" ...Read moreSee 2 more doctor answers
High dheas, other hormones normal. Not pcos. What can be other reasons for high dheas? What medicine should I take? Metformin increased dheas levels
How high?: Chronic stress has the potential to increase the dheas although it doesn't do this in everyone. Rarely an adrenal or ovarian tumor can raise the level but almost always raises testosterone also - which you report is normal. Dheas can have weak "male hormone" effect, causing mainly increased unwanted hair growth. Typically one counters this oral contraceptives and, sometimes, spironolactone. ...Read more
My TPO and TSH levels are very high, but T3 (liothyronine) t4 &tsh are in range. I have a history of graves disease. Why are my antibodies high but other levels ok?
Endocrinologist: You state that your tsh is very high and also state that it's normal in the same sentence. Your graves disease must have been treated with either RAI or medications and this usually leads to an underactive thyroid causing a high TSH which would mean that a higher dose of thyroid replacement is needed. Elevated antibodies could indicate intervening Hashimoto's thyroiditis. See an endocrinologist. ...Read more
What are factors that determine someone with hypothyroidism must be on synthroid (thyroxine) forever?i have it(just high TSH)other thyroid hormones're normal
Failing thyroid: Most likely you have Hashimotos thyroiditis, which is gradually "eating away" at your thyroid. Your doctor could check TPO antibodies. Your gland may not be totally dead now, but it likely will be eventually, but total hypothyroidism and a dead gland could be in 3 months or 10 years. Probably best to take your synthroid (thyroxine) to avoid the symptoms of hypothyroidism, but talk to your doc. ...Read more
What can cause high TSH level after several years of Synthroid (thyroxine) for post ablative (graves) hypothroidism?
Usually low Thyroid : Post ablative hypothyroidism is a condition where the thyroid gland is not functioning well and thus the patient needs more thyroid hormone. A "high tsh" actually mean there is not enough thyroid in the blood, thus an increase in dosage of the synthroid (thyroxine) is needed. Go see your family doctor and he/she will make adjustments and recheck the TSH level. This is very sensitive to thyroid in the body. ...Read moreSee 1 more doctor answer
Can Lamotrigine (Lamictal) affect TSH levels?
Also, what do low TSH mean (if T3 (liothyronine) and T4 are normal)?
Not alot: Thyroid interaction is not common with Lamictal, however as with all medications for each individual that can be a possibility. As to your low TSH that is usually a resonse to elevated T3, (liothyronine) T4. Remember that there can be variations in your thyroid measurements from one time to another. How do you feel. Do you have thyoid symptoms: cold, tired, fatigued, skin or nail changes? ...Read more

When and where did u get the labs? Under what circumstances? ...Read more
TSH=0.04(0.4-4.5mIU/L)FreeT4=1.5(0.8-1.8ng/dL)FreeT3=2.5(2.3-4.2pg/mL). Have Hashimotos disease, on 112mcg Synthroid. why is tsh so low FT3/FT4 normal?
Any symptoms?: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, just one parameter, in this case TSH, slightly out of whack is not a cause for alarm. You may watch and wait. If your clinical situation changes it may warrant repeating the tests. Wish you good health! ...Read more
