My daughter is hypo she takes 100 levo and past 2 blood tests showed supressed tsh but in range t3 and t4 but nearer higher range. She been very poorly with stomach and nack pain and nausea for past few months as yet no diagnosis she had bloods done last week and t4 tsh out of range but this time she had took her levo tablet just 3 hours before test and usually doesnt
Tsh 0.01 (0.38-0.58)
T4. 19 (7.4-13.3)
T3 6.2 (3.8-6.2)
Is this causing her to be hyper? Many of her symptons disnt disappear even when on 100 and we were trying the supplements until she got ill . Also her ferritin was midbrange in novemnber bow its 175 in a range 70-118 they tell me this is fine but she dont eat meat fish or anything really with iron in how is this posible any advice welcome

Some vegetables contain iron. Does she eat eggs? They contain iron.
But, then again, did they test her CRP? CRP indicates inflammation somewhere in the body. And high levels of inflammation can cause ferritin to be high.
If your daughter took her levo just before the test, that FT4 level is a false high. She should leave a gap of 24 hours between her last dose and the blood draw. But, it wouldn't affect her FT3 or TSH. TSH is affected by the time of day, so what time did she have the blood draw? Her FT3 is right at the top of the range. This is unusual in someone just taking levo only.
She is not hyper - she cannot be hyper because she is hypo, and the thyroid cannot jump from one to the other. However, there is an autoimmune conditions - Hashimoto's Thyroiditis - which does cause levels to go high occasionally. Has she had her TPO antibodies tested? That is the way she would find out if she has it.
Notmally she dont take the levo bit forgot this time she had bloods at 5 pm . Her tpo was mid range when last tested in november so said normal . She doesnt eat the veg that has iron just maybe beans once a week . They will want to reduce levo now cause of bloods but we want our facts to argue case thankyou
5 pm is much too late to have bloods. The TSH will be at it's lowest at that point. So, one way and another, those bloods are not good. Try and get them to retest before taking any action.
You didn't say if she'd had her CRP tested, which could account for her high ferritin.
One negative TPOab test does not prove she doesn't have Hashi's.
T3 is the active thyroid hormone which controls the metabolism and therefore the symptoms. Your daughter's Free T3 is right at the top of the normal range, which is good, so she should not have hypothyroid symptoms.
As she is still having what appear to be hypothyroid symptoms, one possible cause is a genetic condition: Impaired Sensitivity to Thyroid Hormone (more often known as Thyroid Hormone Resistance). It causes hypothyroid symptoms and requires very high T3 levels (often above the top of the normal range) in the body to overcome the resistance.
As it is genetic if there are other family members with thyroid problems, fibromyalgia, CFS, ME, Coeliac Disease, MS, Heart Disease or depression this would further support this possibility. Even if you cannot identify any family history of this, it is still possible that she could have this condition.
