My free T4 is high 19.30 pmol/l and my TSH is also high 4.530 mlu/l. What does this mean?

My free T4 is high 19.30 pmol/l and my TSH is also high 4.530 mlu/l.  What does this mean?

Few possibilities: These labs seem at odds, with TSH suggesting overactive thyroid and ft4 underactive thyroid. Free T4 tests can be inaccurate in some people who have interfering substances present. Another possibility is a tumor in the pituitary secreting too much TSH resulting in thyroid overactivity, and high thyroid hormone levels. This is quite rare, however. Your doctor can help sort this out. ...Read more

Not a whole lot!: An elevated TSH is the main criteria most docs use to diagnose hypothyroidism. While most docs feel it is not abnormal unless above 5.6 or so, many endocrinologists feel anything above 3 is abnormal, and some even feel a level above 2 could indicate problems- see http://abt.Cm/1562fwq actually, many with a totally normal TSH may still have thyroid problems- see http://bit.Ly/18atkro & comment:. ...Read more

Tsh, 3rd generation with reflex is 0.46 - what does this mean?

Tsh, 3rd generation with reflex is 0.46 - what does this mean?

Not a problem: Although a TSH of 0.46 is slightly below the normal range, I have never seen a patient with a similar TSH who needed any treatment. Most likely your T4 level is fine and i would view the TSH as a normal variation which has no significance for your health. ...Read more

What does it mean if my Tsh 3rd generation is 5.51 and my Free T4 is .8? Do I have a thyroid problem?

What does it mean if my Tsh 3rd generation is 5.51 and my Free T4 is .8?  Do I have a thyroid problem?

Yes: Your thyroid gland is under-active and you should follow your doctor's advice in taking thyroid medication to maintain health. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

My TSH 3rd generation test is 7.55uiu/ml, ft3 and ft4 is normal what does mean? What is a treatment for this?

My TSH  3rd generation test is 7.55uiu/ml, ft3 and ft4 is normal what does mean? What is a treatment  for this?

U R hypothyroid: Hi. Those labs demonstrate you have subclinical hypothyroidism: your thyroid is failing, but with a little more "push" from the pituitary (elevated TSH), it's still putting out normal T4 and T3 (liothyronine) amounts. Your TPO &/or thyroglobulin autoantibodies are probably elevated - Hashimoto's. I would treat you. No sense waiting until it's over to start. Treatment is cheap, easy, & perfect. Good luck! ...Read more

My TSH 3rd generation level came back at 9.490. MY T4 was normal and T3 (liothyronine) was low.Taking 200 mcg. What do these numbers mean?

My TSH 3rd generation level came back at 9.490. MY T4 was normal and T3 (liothyronine) was low.Taking 200 mcg. What do these numbers mean?

Still hypothyroid: Not sure how long u have been on thyroid replacement, but if been on 200mcg daily over 6-8 weeks, likely require increase dose. If u have just had u'r medication adjusted the. Repeat TSH usually done in 6 wks; the numbers show that u'r body is still in hypothyroid state and that u'r thyroid gland is making less and less hormone or the T4 is not being converted to T3, (liothyronine) so thyroid medicine needed ...Read more

Normal, but...: THIS IS A NORMAL THYROID SCREENING TESTS. There are rare diseases thyroid that can happen with an normal normal TSH, but you would have symptoms of thyroid disease or other evidence of central hypothyroidism or thyroiditis in a "euthyroid phase," which would be rare and require much more history. If there is ongoing concern see an endocrinologist. IF YOU GENERALLY FEEL WELL GREAT, IT IS NORMAL! ...Read more

My t4 is 5.80 my T3 (liothyronine) uptake is 37.8 my FT4 INDEX is 2.2 my tsh 3rd generation is 97.352 i was put on meds 75mcg i need to know what this means help?

Hypothyroid: Both the T3 (liothyronine) uptake and FT4 Index are indirect evaluations of thyroid hormone levels. Briefly, the total T4 is a reservoir for active hormone (T3 (liothyronine)). If the body senses low T4 or T3 (liothyronine), then it secretes TSH to tell the thyroid gland to make more hormone. Your TSH being 97 (normal ...Read more

Thyroid; test results came back .TSH 3rd Gen. 10.580 H What does this mean?

Thyroid; test results came back .TSH 3rd Gen. 10.580 H What does this mean?

Hypothyroid: Your thyroid is not producing enough thyroid hormone, so your brain is producing extra TSH(thyroid stimulating hormone) to tell the thyroid to produce more thyroid hormone. You need to be placed on Synthroid (thyroxine) to replace your hormone and have your TSH rechecked in 6-8 weeks to see if the dosage is correct. This will likely be a lifelong treatment. ...Read more
