Comment on spoilt blood test please

I posted on Friday about having a call about spoilt bloods and having to rush in to nurse to have another.

I have my results today and oddly they have tested thyroid on first bloods (how if they were congealed ) and liver , bone Etc on second sample .

I have been taking , after a rocky start , firstly 5mcg and 10 mcg for the last few weeks.

TSH 0.12mu/L. ( 0.35. - 5.5

T4. 17pmo/L. (9. - 23 )

T3. 5.5pmol/L. (3.5. - 6.5 )

Results in April

TSH. 5.76mu/L

T3. 4.1 pmol/L

T4. 15 pmol/L. Same ranges as above

Any advice welcome !

PP, Results are excellent, TSH low, FT4 mid-range and, FT3 near top of range. Do you take Levothyroxine too?


Yes Clutter


Why do I STILL feel Crap 😱 ? Lol



PP, symptoms can lag behind good biochemistry by a couple of months. Are ferritin, vitD, B12 and folate optimal?


Clutter , yes everything is fine .

I was going to take another 5 of T3 today making 15 . What do you think?

Endocrinologist put me on 20mcg a day and I felt ill.

I followed your advice and stopped it and then started reintroducing after a couple of weeks.



PP, try the extra 5mcg. It will put you at top of FT3 range. If you feel hyper cut back to 10mcg.


Thanks Clutter

Still looking for that sweet spot that you and I think shaws described when I first came to Health Unlocked .

Best Wishes



PP, Having corrected vitamin deficiencies and low levels and found my 'sweet spot' with T4+T3 I certainly don't feel as well as I was 7 years ago before thyroid nonsense started. I'm a heck of a lot better than I was 5 years ago though.

Good to know Clutter.

I lost weight when I was Hyper and never put it back.

I know weight is a sore point on here , but I could ill afford to lose it as I am tall and slim.

I have noticed that I have dropped another 2or 3 pounds and hope it's not the T3 as I am beginning to resemble a 73 year old stick insect which is not a good look.

Cheers pp


PP, low weight is a problem for me too. I gained 13kg in 6 months and loved how I looked. In hindsight I suspect it was the onset of Hashi's but at the time I felt very well. 2 or 3 years later I felt very hyper and ill and lost 13kg in 10 months. I lost another 7kg when I was switched to Levothyroxine. It's taken 3 years to gain 3kg and I'd be happy to gain another 4-5kg.


Let me know if you find the secret Clutter.

I hope it's not the T3or I will have to stop it. 😕

Many thanks for you replies.



PP, I put a little weight on when I was on T3 only and lost it when switched to Levothyroxine.

I don't eat enough because I don't have much appetite. Eating more is probably the secret.



That would leave me out then. I don't eat a lot but I do snack between meals.

Are you not good on T3alone?



PP, I was recovering but not well on T3, but I was only on it for 3 months. I have no idea what thyroid levels were, other than TSH was probably suppressed, so I could have been over or under replaced. I was switched to T4 after RAI and felt poisoned but I was considerably over-replaced to suppress TSH and FT4 was very high for months. Dose was reduced over months but I got worse, not better.

T4 only causes me a lot of adverse effects but the addition of T3 calms them. I like the security of having some T4 in my system to see me through if there were to be shortages of T3 or I wasn't well enough to take thyroid meds for a couple of days.


I'm glad you have it Sussed Clutter.

I hope you stay well !

Pp x


Thanks, PP.
