help with test resault
tsh 0.7 (ref 0.4-4.0)
t3 1.2 (ref range 1.2-4.14)
t4 145 (ref 59-161)
i had another test that showed my free t4 is low 7 and the reference is 10-20
and free t3 is at the low border
so my free t4 is low and t4
is normal
what does that mean?

I became hypothyroid over 40 years ago. It took me a long time to finally convince a doctor that I needed a trial of thyroid med. My Free T4 was always in the low end of its range. In order to try and eliminate hypothyroid symptoms my dosage finally got to 200 mcg of T4, and I still had lingering hypothyroid symptoms, which I learned later was because my body was not adequately converting the T4 to T3. About 8 years ago I learned about the importance of Free T3 and got tested and confirmed as low in the range. Convinced the doctor to switch me to a desiccated type med with both T4 and T3. After some tweaking of dosage, I felt better than I could ever remember. Since that time I have spent a lot of effort researching hypothyroidism so that I could help other members.
So, yes there are people with FT4 and FT3 that are low in the range, yet they still have hypothyroid symptoms, because as I mentioned hypothyroidism can be caused by more than just low levels of thyroid hormone. Plus being just inside the lower range limits does not mean that is optimal for you. You can read about that in the link I gave you above.
Also, Vitamin D should be at lest 50 ng/mL so you need to supplement with D3 at about 4000 IU daily to optimize. And of course you need to get additional tests done and find a good thyroid doctor. From what your doctor said, I doubt that he will be of any further help to you. We have some limited knowledge about good thyroid doctors. Where are you located?

No, there are no doctors active on this Forum. We are thyroid patients like you, who have extensive knowledge about hypothyroidism due to our own experience and research over many years. If you want to verify what you are told here, you can read the following link.

Regarding what your doctor said, I don't understand how he decided that the old tests were wrong. If he is convinced they were wrong, then it seems that he should re-test and confirm Free T4 and Free T3 levels? It is true that Thyroid Binding Globulin (TBG) binds most of T4 and T3, leaving only small portions that are called Free T4 and Free T3. If he suspects that your TBG level is too high and would be the cause if your Free T4 and Free T3 levels are too low, then why not also test TBG and liver/kidney functions to confirm if they are okay or not?
Hypothyroidism is not just a result of Free T4 and Free T3 levels. Hypothyroidism is insufficient T3 effect in tissues throughout the body, due to inadequate supply of, or response to, thyroid hormone. There are additional variables that affect this Tissue T3 Effect, including cortisol, Vitamin D, and ferritin levels. So I would request tests for each of those along with TBG and Free T4 and Free T3. I would also request a test for Free Testosterone.
Has the doctor explained what further tests/evaluations he has planned for you?

was it low or normal? are there people with hypothyroidism and have normal total t4 and t3? sorry for asking too much
i really appreciate your time and effort in answering me
i dont know why he didnt tested the free t4
he made me mad because cost me money and effort on test i didnt need
i have low vitamin d3 17 reference 10-80

hello
i went to doctor he tell me to repeat the test
i thought the will mesure free t3 and t4
but they measured total t3 and t4
the resault is
tsh 1.2 normal range 0.270-4.200
total t4 118.2 normal range 66.0-181.0
total t3 1.30-3.10
the doctor said that my thyroid 100% normal
even i told him that older tests showed free t4 and free t3 is low
he said the old tests is wrong
hr said free t4 could be low while total is normal only if have problems with the protien
if i have problem with the liver or kidney
what do you think?
and please tell me are you a doc or a hypothyroidism patient?
could i have hypothyroidism while my total t4 and t3 are normal?

total t3 is 2
normal range 1.3 to 3.1
normal range 1.3 to 3.1
You have symptoms that are frequently related to hypothyroidism, plus your Free T4 and Free T3 are way too low. Along with that your TSH is toward the low end of its range, so it appears that you have central hypothyroidism. with central hypothyroidism there is a dysfunction in the hypothalamus/pituitary system that results in TSH levels that are too low to adequately stimulate the thyroid gland to produce hormone.
You need to see a good thyroid doctor that will treat you clinically, by testing and adjusting Free T4 and Free T3 levels as needed to relieve hypo symptoms, wiithout being influenced by resultant TSH levels. Symptom relief should be all important, not just test results. Many of us have found that we needed Free T4 at least mid-range, and Free T3 in the upper third of its range, and adjusted from there as needed to relieve hypo symptoms. In addition, you also need to be tested for cortisol, Vitamin D, B12 and ferritin. Having adequate levels of all four are important for a hypothyroid patient.
Good thyroid doctors are hard to find, so it you are located in the U.S. tell us your location and perhaps we can suggest a doctor that has been recommended by other thyroid patients.

but i dont have weight gain
so could a skinny person has hypothyroidism
so could a skinny person has hypothyroidism
Free T4 is more revealing than Total T4. A Total T4 test represents all the T4 in your blood. Only a small portion is not bound to protein and thus rendered biologically inactive. The unbound portion is called Free T4. Same for Free T3. So Free T4 and Free T3 are the most important thyroid related tests. The main value for TSH is to distinguish between primary and central hypothyroidism.
Having low Free T4 and Free T3 means that you are most likely having hypothyroid symptoms. So please tell us about any symptoms you have. Also, have you seen a doctor about those test results?
