Thyroid :: Low TSH Normal Free T4
Jan 28, 2014
I am getting really frustrated with my dr. D not really giving me answers! In april 2013 my TSH levels were .48 (within normal range) I got tested last week on Friday and my TSH levels are .25 and my free T4 is 1.1 (within normal range). I have been feeling really sick lately with very bad nausea (I am not pregnant) and have just been feeling really down with a rapid heart rate of 103 bpm! My dr says I'm obese and that's why I am having these symptoms but seems to be ignoring my thyroid test results. Is it because it's not low enough to worry about and it's really no big deal yet? I also have many nodule and one takes some color.

My son had some blood work done due to chronic diarrhea among many other things (he's on the autism spectrum, ADD, sweetest kid ever-had to throw that in) and we were trying to rule out celiac and who knows what else. Anyway his TSH and Free T4 were normal, but his Free T3 was slightly high. We rechecked it 4 weeks later and it's still just slightly high, with the other numbers being normal. His doctor thinks we shouldn't worry and should just monitor, I'm just looking for any advice if anyone has seen this because I keep reading that typically Free T3 is high when TSH is low?

I just received my latest thyroid lab results and my TSH was a 0.06 (range 0.34-5.60) and my T4 FREE is 0.99 (range of 0.61-1.12). My Dr said to continue my dosage of medications and we would recheck in a year. Should I be concerned

I've had Hashimoto's Disease for 12 years and started taking Levothyroxine. For the past 8 years, I've been on a constant dose, and been very happy with no symptoms of hyper or hypo. Recently I moved and had to go to a new dr, who is very upset about the low (almost zero) TSH even though my Free T3 and Free T4 were normal. She wants me to totally go off all Levothyroxine for 6-8 weeks to "reset" my pituitary. I am very worried about what will happen to me if I did this. I tried going down in dosage, but all my hypo symptoms (gained 10 lbs in a month, extreme lethargy, depression, etc.) returned. Anyone out there have any ideas on what to do?

I got labs done and my tsh is 4.83 range .50 to 4.30
Free t4 1.5 range .8 to 1.8
Free t3 3.8 range 2.3 to 4.2
My ferritin was extremely low only 13
My issue here is my free t3 and free t4 are both In the upper range yet my tsh is high do I have hypothyroid ?
I have joint pain and hairloss . I'm a 19 year old male . Many women in my family have hyper and hypo thyroid issues .
Looking at my t3 and t4 my thyroid looks optimal to me yet the high tsh has me confused .
I have no issues gaining or losing weight I just have a very puffy face .

Last week I found that my my TSH was 5.73 mIu/L and shortly after that, that my Thyroid Peroxidase AB was 393 Iu/mL. My T4, Free came back at 1.3 ng/dI which I believe is in the normal range. I am currently waiting on my Thyroglobulin AB. Has anyone has an elevated TSH and Thyroid Peroxidase AB but a normal range T4 and still been diagnosed with a Thyroid problem?

I am 37 years old and about 16 weeks pregnant. When I had my first set of prenatal labs, my TSH came back as low at 0.0643. They called me back in to do a thyroid panel, and I just got my results back which were TSH 0.092, free T3 3.6, and free T4 0.95. The nurse made note that T3 and T4 were in normal range, but TSH is "very low" and they referred me to maternal fetal medicine. The doctor's note says "may need small dose of Synthroid."
I am very confused now. Doesn't a low TSH mean HYPERthyroidism? And wouldn't Synthroid be for HYPOthyroidism? I am finding so much conflicting information online, and I have to wait until my appointment on the 21st to get an answer on all this. Of course, it's all making me very nervous. Can someone help explain or shed some light on my lab results as far as what they could mean? I was seeing that a lower-ish T4 and low TSH can actually indicate hypo, so I'm really confused now.

I am a 51 year old female and had a physical last week with my general practitioner because it has been a long time. It included blood tests. One test was about the thyroid and I've got conflicting information about the result.
The report says:
TSH Reflex to Free T4
TSH RFLX is 8.25 - and is high, the normal range is shown as 0.40-4.50
T4, FREE
Thyroxine, Free, Direct - 0.8 - and is in range, range is shown as 0.8-1.8
I've done some research and it looks like this combination falls in the hypothyroidism range. However, my doctor says it is fine because the T4 FREE number is in range. There is no family history of thyroid problems. I'm concerned because I have some of the symptoms of hypothyroidism (fatigue, depression, feeling cold).
Does this sound right to those of you who have experience with thyroid disease? Should I see an endocrinologist?

Here are my lab results from 2/7/14:
tsh- .028 range- .45-4.5
t4 free direct- 1.86 range-.82-1.77
t3 free serum- 3.2 range- 2.0- 4.4
Last year:
lab results from 3/26/13:
tsh- .096 range- .45- 4.5
t4 free direct- 1.53 range- .82- 1.77
t3 free serum- 3.1 range- 2.0-4.4
It looks like I might benefit with the addition of t3 meds. (cytomel) to lower my free t4 and raise my free t3. I feel fine, and anytime I've tried to lower my dose of levothyroxine (.125) even a little bit (.112), I get brain fog, lethargy and GI symptoms. I've been on the same dose for 13 years and my tsh has been low since I started medication. I've only recently requested the free t3 & free t4. My main concern with adding cytomel is that it will further reduce my tsh & the dr will be concerned. This is my 3rd dr in the 7 years since I moved south & every one has been concerned about bone density & heart issues. Any suggestions when I talk to the dr? btw- no hyper symptoms :-) Thanks!

I had RAI done long ago and been on Synthroid 175. My test always come back with low TSH, high free T4, and low Free T3.
My last results were 1 week ago...
TSH .012
Free T4 1.48 (range .52-1.21)
Free T3 2.09 (range 2.20-3.80)
I have depression and would like get my thyroid ranges in a more normal profile to see if it had a positive effect on the depression.
I have tried cytomel which made me feel hyper at only 5mcg, but only tried it for a few days...
Thanks for any suggestions....

I've been on dessicated thyroid for a few years and my dosage is still not right.
I feel worse than I ever have - I have no energy, so completely exhausted but have trouble sleeping or fall asleep during the day. Iron level is fine. Here's my latest test results, which my doctor said is fine, to leave dosage as is:
Result Reference
Thyroid Stimulating Hormone [TSH] 2.55 0.30 - 4.00mIU/L
Thyroxine Free [Free T4] 10 9 - 23pmol/L
Triiodothyronine Free [Free T3] HI 7.3 3.5 - 6.5pmol/L
Desperate to find out what's wrong with me - please help.

I have been having low free T4 (9 pmol/L), but normal although on the lower end TSH (1.69 mIU/L).
My doctor has put me on 75mg/day synthroid, because his diagnostic is hypothyroidism. However, I understand that hypothyroidism is normally associated with low T4, but high TSH.
Based on what I have read, it seems that a low T4 associated with a normal TSH may be linked to issues with the pituitary gland (and not the thyroid) or issues with binding agents.
Is hypothyroidism and the use of synthroid indicated in my case?

I've been told I have post surgical hypothyroidism (left side, 2010) but TSH is consistently low (0.1) or low normal (.396), I don't understand the hypothyroid diagnosis with a low TSH. Can someone explain? I also had left temporal lobe brain tumors (cancerous) and gamma knife radiation. Could this be affecting the TSH level. I have many hypothyroid symptoms, basal body temp is on avg. 96.5, weight gain, tiredness/fatigue....blah, blah, blah. My endo doesn't do too much. Currently taking 50ug of levothyroxine 6 days/week and feel horrible. There are also 3 nodules in the right side now that continue to enlarge. Any answers? Thanks.

I've been on Synthroid medication for 20 plus years and have done pretty well on it until recently. This routine test showed a TSH level > 100 and my Free T4 at .24 which is low. I've been placed on Synthroid at 300 mg and I'm waiting to see a specialist. In the meantime, I'm wondering what does this means?

I have seen some videos that support a gluten free diet and an end to Hashimoto's.
Has anyone tried going completely gluten free and had an improvement in their symptoms or even and reduction or end to their meds?

For sometime I have had panic attacks and frequent infections of chest and ears and viruses.Last April things moved on quickly and I was covered in painful itchy blisters, neuropathic pain, vertigo and feeling shut down. I was covered in bruises. Ambulanceman reported an ischaemic looking ECG and took me to A and E.
The only findings wee raised TSH with normal free t4 and normal Thyroid peroxidase abody. Also raised basophil and eosinophil. They said hypothyroid but my GP says no as no autoantibodies?
I am still suffering-eyebrows gone, no energy, dry wrinkled skin and 3 more courses of antibiotics for chest and throat infections. Any ideas, anyone? Also sight got really bad and joints ache ++
