What Should My T4 Level Be
My potassium has tested at 5.4 on a range going to 5.2 twice. Should i be concerned? What should be done?
High potassium?: Your potassium (k) level is not that high. High k may be due to chronic kidney disease, or addison's disease, . One less serious cause is due to rupture of red cells during the draw of a blood sample. For more info on high k levels see: http://www.Mayoclinic.Org/symptoms/hyperkalemia/basics/causes/sym-2005077. I would not worry about your k level. If you are, see a nephrologist for more help. ...Read more
I have a TSH level of 5.69 and just found out that my T4 level is 1.1. What does this mean? If my t3+t4 is normal then what could be the problem?
How Abnormal?: Not knowing if your free T4 abnormality is high or low, I am not able to give you more information. Please provide any details you may have about your thyroid testing. Thanks! ...Read more
No worry: Hi. Your thyroid is experiencing some autoimmune reaction (usually an attack), but is maintaining normal function. The thyroglobulin antibodies (and TPO antibodies also) mark the autoimmune process, but do not themselves cause any harm to the thyroid (or anything else). This is usually called euthyroid Hashimoto's. No treatment is warranted until your TSH (+/- free T4) becomes abnormal. Good luck! ...Read more
Need help docs! my blood test showed a hba1c level of 6 (the maximum range level is 5.7). How concerned should I be and what dietary changes should I make?
6 is still good: A Hba1c of 6 is still good. You should be mildly concerned but determined to make significant lifestyle changes to lose weight, increase exercise. Now is the best time to do this, before the effects of diabetes set in making it harder to lose weight. Right now your body is just a 'little' off and resetting it will be easier than when it is 'way' off! ...Read more

My ALT was elevated to 49 in 2009. Now is elevated to 89. My doc don't know why? What could this be and should I be worried? Hepatitis?
Find cause: If you're overweight and have polycystic ovary disease, the smart money is that this is metabolic syndrome and you'd be doing yourself a huge favor by adopting an aerobic-fitness focused lifestyle -- this would be serious and fitness is your best rx. You will probably be checked for hepatitis b and c, hemochromatosis, wilson's and autoimmune hepatitis. ...Read more
My TSH is high with 18.7 and T3 (liothyronine) is 112 , T4 is 5.3 which shows in normal range ...What should I do...Is it harmful to my my body if i not treated?
Underactive thyroid: Total t3 (liothyronine) normal values: 80-200 ng/dl ( for your age ) total T4 normal values: 4.25-12.5 mcg/dl ( for your age ). Your values suggest subclinical hypothyroidism. Nevertheless, T4 is in the low end of normal and t3 (liothyronine) too. I would like to see the values of free T4 and free t3 (liothyronine), a i-123 thyroid scan and a 24 hours urine collection for iodine. Yes, you should be treated. ...Read more
Potassium level is 5.4 on a range going to 5.2. Test and retest were the same. Should i be concerned? What could be wrong?
Elevated potassium: This can occur from certain birth controls (drosperinone containing) and other medication. Elevated potassium in your case might be normal or it could be a sign of kidney issues - it has implications for your heart and muscle function - please be sure to follow up with your physician. ...Read moreSee 1 more doctor answer
My TSH level is 33.02 and serum free T4 is 9.6 my doctor has upped my tablets. What should we be aiming for?
Normal range: It varies slightly from lab to lab but normal TSH is usually from 0.5 to 5.5 and normal free T4 is 0.7 to 2.0. Good luck and I hope your next labs are in normal range. ...Read more
Would TSH 5.4 and T4 7.6 be considered mild or severe? What test would my doctor have to do to know what caused my thyroid to be low?
Mild; repeat test: In most assays, the T4 is normal, and TSH slightly elevated. This could be nothing; sometimes a repeat test will come back normal. The question to ask: is your thyroid gland starting to fail? If so, it is early. Family history? Do you have symptoms? Positive anti-tpo antibodies? If you have symptoms and if there is evidence that your thyroid is failing, you should start on levothyroxine. ...Read more
My thyroid levels were checked just recent and my TSH was 2.08 and my T4 was 14. Could this be causing the anxiety feeling? What is protocol?
TBG: Total T4 isn't a very useful test. Any female taking birth control pills, for example, could have an elevated T4 because thyroid binding globulin might increase. A free T4 would be much more helpful. With a normal tsh, it isn't likely that you're hyperthyroid. Elevations in thyroid hormone levels should suppress TSH in people with primary hyperthyroidism. ...Read moreSee 1 more doctor answer

What do you suggest if my TSH level is 0.11 free T4 is 15.4 free T3 (liothyronine) is 4.8 should I be on medication is so what.?
Something wrong: Hi. In the labs we use, if your FREE T4 was really 15.4, your TSH would be undetectable. Is it a total T4 (a test NO NONE should ever order, but some old docs still do)? That TSH is either a brief snapshot of a changing TSH, or if stable at that value, a hyperthyroid nodule (1 or more). We would need more history or a nuclear medicine thyroid uptakes and scan. Good luck! ...Read more
I'm 28, my Ferritin Level was checked, test result was 10.8 and the Dr has not shown concern. Should I get 2nd opinion, how should this be treated?
Don't treat a lab: This is just below the lower limit of normal for a young woman for most labs. It would be worth looking at your monthly losses and dietary intake -- if the iron loss is heavy and you don't eat a lot of meat and don't take a supplement with iron, this is probably your explanation. If this isn't the case, I'd check to be sure you're not losing blood from your gut (bleeding ulcer, tumor). ...Read more
Hi, I have tested my prolactin level and it came as 20. Do I need to worry about it. What is the normal range? How much high level can cause concerns ?

With a TSH level on 3/15 was .1 taken again on 4/17 the result was .40, my current doctor does not appear to be worried, should I be?
TSH: Tsh levels can fluctuate based on various factors. Are you taking medications such as levothroxine for hypothyroidism? If so, your second TSH result .40 is within the recommended target range. If you are not taking levothyroxine, your first result .1 is slightly on the lower side, you may have subclinical hyperthyroidism. So it would all depend on the context. Talk to your doctor. ...Read moreSee 1 more doctor answer
It can mean: An elevated level of thyroid hormone, either due to hyperthyroidism or thyroid inflammation. It can be falsely elevated by estrogen therapy. Other thyroid tests are more reliable. The T3 (liothyronine) you're receiving is potentially dangerous and should not be taken. It can not me measured in the blood and has potential toxicity. Use brand name T4 only if replacement is required, . ...Read more
Yes: Total T4 reflects T4 bound to proteins in your blood. Free T4 measures the amount of T4 that is free and not bound so that it can be metabolically active. Thus women taking Estrogens (as in bc pills) have elevated levels of thyroid binding globulin and elevated total t4, but normal free t4. ...Read more
Tsh > 40 mU/L: All infants with a low T4 concentration and a TSH concentration greater than 40 mU per L are considered to have congenital hypothyroidism and should have immediate confirmatory serum testing. Replacement levothyroxine (LT4) treatment should be initiated as soon as confirmatory samples have been taken, without waiting for the results ...Read more

Thyroid disease : T4 level assays can range from 60 -150 for normals. Propranolol is used to effectively relieve the symptoms of palpitations, tremor, and anxiety. It has no effect on thyroid hormone secretion. Tsh is and excellent test to see if thyroid disease is under adequate control. ...Read moreSee 1 more doctor answer

Hypothyroid: It would be helpful to know what units those test results are. TSH is typically measured as mIU/L or micro IU/ml, with normal ranges up to 4.5. Total T4 is typically measured as micrograms/dl with normal ranges of 4.5-12, but can also be measured as nmol/L with normal ranges of 60-160. The TSH appears to be out of proportion to the T4 level, but you should be taking thyroid hormone. ...Read more
