hi my routine blood results have just come in. ive been really up and down with energy a lately . my tsh is 0.02 and ft3 55 and my ft4 is 19 . can anybody tell me if these seem okay or am i to be worried
low tsh : hi my routine blood results have just... - Thyroid UK
low tsh
Please add lab ranges for free T4 and free T3. You can edit your post with the "more" button on the right : )
tsh range 0.35 to 4.70 t3 3.80 to 6.00 t4 7.80 t0 21 been feeling really ill. my serum bicarbonate is low. my adjusted calcium level is high . my lymphocytes is high . my serum albumin is low ,my white blood cell count is high too,
So are these your results (sorry it’s easier to read if laid out as a list)
FT4 19 (7.8-21)
FT3 55 (3.8-6)
Is that FT3 correct? Are you hyper?
looks like i am ive been like this for years up and down . but my tsh has never been that low . sorry how i put it out im useless at keyboard .
my tsh is 0.02
Are you on medication? Don’t worry about your TSH, mines 0.005 and I’m healthy. It’s your FT3 that needs your concern. How do you feel?
i feel really shit, twitching and spasm around my face and body headaches no appitete
why my free t3 ?
FT3 55 (3.8-6)
That's why your FT3. 55? That would be rediculously high - especially compared to the FT4. Did you forget a decimal point somewhere?
it deffo says 55
no sorry it is 5.6
OK!!! That makes more sense. lol Well, your FT3 is high, but not over-range. Your FT4 is good, and you convert very well. So, don't worry about the TSH.
Have you had your nutrients tested: vit D, vit B12, folate and ferritin?
yes b12 ... 273 pmol/l range 115 to 1000 folate 4.4ugl and ferritin 55ugl
OK, so all those are much, much too low. And, that's probably why you are feeling bad. Low B12 can cause hypo-like symptoms. Are you supplementing any of them?
Get your doctor to try you on something other than levothyroxine. I have had a nightmare experience with that drug. I did okay on Armour and Synthroid was okay but gave me severe joint pain. I've just started Tirosint and I think it's okay too. Levo was super agitating in all the worst possible ways. It was truly awful, but all my numbers were in order, so it wasn't suspected to be a problem.
Ignore TSH.
Your T3 is too low. You don’t seem to be converting T4 into T3 which is the active part.
so what does all this mean because i dont understand it . my doc said my free t3 is high free t4 high and tsh low,
The OP's FT3 is reported as 55. That is not low. That is very, very high.
thankyou grey goose . i was hypothyrodism for 17 years and now i am hyperthyrodism , my doctor investigating . a lot of my bloods come back abnormal too
No, absolutely not! A low TSH does not make you hyperthyroid. It is low because your Frees are in a good place. Ignore it. And, don't let your doctor reduce your thyroid hormone due to a low TSH.
You would have been hyper with an FT3 of 55, but that's not the case.
So, what are you taking, and how much?
Have you had your antibodies tested?
not had my antibodies checked yet , i think thats the doctors next step. im not constipated anymore since my tsh has lowered .i am on 100mcg levo
OK, so it's perfectly possible that you do have Hashi's. Do you have any other results on 100 mcg levo, for comparison?
Just a technical point: it's not the lower TSH that has got rid of your constipation, it's the higher levels of thyroid hormones, T4 and T3. TSH is a pituitary hormone and doesn't cause symptoms, it's just a messenger between the pituitary and the thyroid, telling it to make more or less hormone.
urea and electrolytes come back borderline calcium adjusted level 2.67 range 2.20 to 2.58 serum albumin low 35gl range 36 to 48 total white blood count 11.4 range 4 to 11 lymphocytes high range 0.80 to 3,40 mine 3.48,,,so god knows whats going on
Well, you have hypothyroidism - possibly Hashi's - that's what's going on. It affects everything. Doctors just don't realise how far-reaching the effects are.
thankyou very much . is hashis hereditary please
Can be. Not always, though.
just that my daughter is still trying for a baby with no success. i have her blood test next wednesday . her last tsh as 3.3 range 0.35 to 4.80.. she didnt have her t3 or t4 done or free t3 or free t4 or her antibodies, i have a family doctor that suffers from thyroid disease himself
why has my tsh gone so low please . i really know nothing about this horrible disease
TSH is a pituitary hormone.
When the pituitary senses that there is not enough thyroid hormone in the blood, it secretes TSH to stimulate the thyroid to make more hormone.
When it senses that there is enough thyroid hormone in the blood, it cuts back on TSH production because you don't need it anymore.
When you are on a good level of thyroid hormone replacement, and your FT4/3 are high in range, the pituitary will almost stop production completely, because it's not needed.
This is not a problem, it is normal. And, it certainly doesn't indicate that you are hyper! For one thing, if you are hypo, you cannot become hyper because the thyroid cannot suddenly regenerate and start over-producing hormone. It just doesn't work like that.
You could possibly be over-medicated, which would cause your TSH to go very low. But, you're only over-medicated if the FT3 is over-range. And yours isn't.
Your TSH is low because your pituitary is satisfied.
Salsybar73 FT3 is 81% through range. That’s a good result.
it is actually in range , because the high is 6 . and my free t4 is in the high range 19 and its up to 21
I wonder if you’ve understood what I was saying?‘Through range’ is a tool that we use to see how ‘good’ or ‘bad’ our results are.
This is why we always need the ‘range’. Fir example my FT3 result for 10yrs was usuallly 3.5 the range was (3.5-65) to my GP this meant that I was fine because I was ‘in range’ when in actual fact the result of 3.5 was very low, any lower and I’d be out of range. I never felt well. My ‘through range’ was 0%. I was saying that your FT3 number being 5.6 was 81% through range. This is a good number.
I use this calculator to work out the ranges. It’s just another tool to help us work out were our optimal is. Our sweet spot.
Hope that helps.
So your thyroid function results look good. Levo is working for you. As greygoose said look at B12 symptoms also a Vit D test would be helpful. Not feeling good might be because your Vits and minerals are not optimal for you.
I’m glad you’re FT3 is NOT 55! That would give you hyper symptoms!
Remember that TSH is Thyroid STIMULATING hormone
How much thyroxine is in the blood
|
Hypothalamus - sends a signal (TRH)
|
Pituitary - sends a signal (TSH)
|
Thyroid
This is the feedback loop. Your body detects that you have enough thyroxine in your system and so your thyroid doesn’t need stimulating ( but remember that your thyroid is broken, that’s why you went on Levothyroxine in the first place, no amount of stimulation was making your thyroid perform adequately. That’s why a high TSH test shows that there’s something wrong because at first our body keeps trying with higher and higher stimulation but to no avail)
Think of the system like a thermostat in your house. You like the house to be 23degrees, you switch your thermostat to that number, the boiler kicks in to warm up the radiators BUT the radiator in your living room is broken, you don’t know this so you still feel a chill, so you turn the thermostat up to 25 degrees. It doesn’t matter how high you turn that thermostat up, the radiator won’t warm up.
b12 ... 273 pmol/l range 115 to 1000
folate 4.4ugl
ferritin 55ugl
B12 and folate are too low
If you have Low B12 symptoms ask GP to test for Pernicious Anaemia BEFORE starting any B vitamin supplements
b12deficiency.info/signs-an...
If GP won’t test,
recommended also to supplement a good quality daily vitamin B complex, one with folate in (not folic acid) may be beneficial.
This can help keep all B vitamins in balance and will help improve B12 levels too
Difference between folate and folic acid
chriskresser.com/folate-vs-...
Many Hashimoto’s patients have MTHFR gene variation and can have trouble processing folic acid.
thyroidpharmacist.com/artic...
B vitamins best taken after breakfast
Igennus Super B is good quality and cheap vitamin B complex. Contains folate. Full dose is two tablets per day. Many/most people may only need one tablet per day. Certainly only start on one per day (or even half tablet per day for first couple of weeks)
Or Thorne Basic B or jarrow B-right are other options that contain folate, but both are large capsules
If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before any blood tests, as biotin can falsely affect test results

Ferritin is a little low
Eating iron rich foods like liver or liver pate once a week plus other red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption

This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.
Thyroid disease is as much about optimising vitamins as thyroid hormones
Also need vitamin D tested
Low vitamins often tend to lower TSH
You’re not over treated as Ft4 and Ft3 are both within range
FT4 19 (7.8-21)
FT3 5.5 (3.8-6)
Don’t agree to reduce levothyroxine dose
Improving vitamin levels will improve symptoms
my adjusted calcium level is high .
my lymphocytes is high .
my serum albumin is low ,
my white blood cell count is high too,
What is actual calcium result?
Ask GP to test vitamin D, calcium and parathyroid levels together
High calcium can be due to high parathyroid levels
Also what’s your diet like
Are you vegetarian or vegan?
If so will need B12 supplements daily
academic.oup.com/nutritionr...
The present review of the literature regarding B12 status among vegetarians shows that the rates of B12 depletion and deficiency are high. It is, therefore, recommended that health professionals alert vegetarians about the risk of developing subnormal B12 status. Vegetarians should also take preventive measures to ensure adequate intake of this vitamin, including the regular intake of B12 supplements to prevent deficiency. Considering the low absorption rate of B12 from supplements, a dose of at least 250 μg should be ingested for the best results.3
I’ll leave the advice to those with more experience than me.
The endocrinologist I saw said she was happy for my TSH to be below range so long as it was detectable & my ft4 and FT3 were in range.
The advice I received here about optimal vitamin & minerals made a huge improvement to feeling well, a slow journey but I have more good days than bad days now.
Is FT3 5.5 or 55? If it is 55 you are very, very hyperthyroid and need to see an endo right now. I suspect you missed the decimal point.
