Help interpreting my blood test results..

[Jim_B]

Hi there!

First time poster here but long time reader. I'm a 26 year old male who had a TT in June last year for the treatment of a Papillary Follicular variant Thyroid cancer, I also had RAI treatment in November. Considering the size of the tumour (8cm) I was very lucky and my prognosis has been good from the start. I'd say im in a position which I imagine many people can empathise with, in that im extremely happy to be essentially cancer free but im still far from feeling good (Brain fog, fatigue, achey, feel down etc) I know its been a relatively short time since my operation but ive done a lot of reading and come to understand if I ever really want to feel 'normal' again I need to take it somewhat into my own hands.

This is where I would really appreciate some input from people who are more in the know than I am. Ive just had my latest blood results back and everything was considered 'within range' and therefore no further action to be taken, but from what I understand in range does not necessarily mean its anywhere near optimal and that's what I would really like to work towards. Im currently taking 175mg of Levo before bed and ive been taking a basic multi vit with iron in the mornings. I think my free T4/T3 levels are looking ok but I was thinking my ferritin and B12 levels are a little low and this could maybe be contributing to some of my symptoms.

TSH - 0.46 miu/L (0.35-5.00)

Free T4 - 17.2 pmol/L (9.0-19.0)

Free T3 - 4.2 pmol/L (2.9-6.1)

Serum Ferritin - 65 ng/mL (22-275)

Serum Folate - 10.0 mg/L (3.0-20.0)

B12 - 337ng/L (140-682)

Any help or advice would be greatly appreciated!

It is my understanding that your FT3 should be towards the to of the range. If you're suffering brain fog etc it is worth asking for a trial T4/T3 combination. I am also TT patient, and I didn't feel at all well on T4 only...I was on the same dose as you and my blood results were similar to yours at the time.

Combination treatment eased the symptoms for me. Good luck.
