I have had fibro for years and share many of the same symptoms of thyroid issues . 6 mnths ago my thyroid test came back borderline and then normal. I had it tested again this week and result printout says normal.

I can feel a lump in my throat or swelling right where my thyroid is and have had gritty eyes this week. If I do have hyperthyroid then the medication could greatly improve my life. I am going to ask my gp for a trial of medication ?

Could somebody translate what these results mean ?

serum free thyroxine 13.9 pmol/L12 - 22

Serum TSH 2.28 mu/L0.3 - 4.2

Thyroid Peroxidase AB Ab 6.2 iu/mL0 - 35

Are there any other tests I can request ?

Larissa, TSH >2 indicates your thyroid is beginning to struggle and your FT4 is low in range, but NHS won't usually make a hypothyroid diagnosis until TSH is >4.20 or FT4 <12.00. Thyroid peroxidase antibodies are negative for autoimmune thyroid disease (Hashimoto's).


Your GP should palpate your throat and neck to see whether a goitre or thyroid nodule is evident and, if detected, arrange an ultrasound scan to check the thyroid gland.

I think it is very important for you to have the FT3 tested and not just the FT4. Sadly this is rarely done on the NHS. Your FT4 level is at the bottom of the range so I am suspecting your FT3 will also be very low.

T3 is needed in every one of the billions and billions of cells in the body - so when the level is low then there is not enough to go around and things begin to go wrong. Could even be one of the causes of your Fibro.

Have you also been tested for B12 - Ferritin - Folate - Iron - VitD. They all need to be high in their respective ranges for you to feel well and for the thyroid hormones to work well.

I was diagnosed with Fibro over 15 years ago and Hashimotos 10 years ago. As my treatment was optimized the signs of Fibro disappeared I am pleased to say :-) It is a long journey of tweaking - reading and learning - and generally listening to your body.

Hope you soon find some answers too....
