Help with results please

My mother's latest results:

! TSH + FT4 repeat test in 6 month

Serum free T4 level 17.6 pmol/L (9.00 - 24.00 pmol/L)

! Serum TSH level. 0.05 mu/L (0.35 - 5.00 mu/L)

She is 81 and frail. She has had a goitre for years and at one stage they were aspirating it every 6 months. They said about a year ago that there was nothing suspect and that they didn't need to see her any more. She has never been prescribed any meds. I didn't have a clue about thyroid issues until recently so didn't question it but now I really want to know what is going on with her!

FMartin, TSH is low but your mother's FT4 is mid-range so she isn't hyperthyroid and doesn't appear to be heading that way. She doesn't appear to have a thyroid issue.

VitD and B12 are often low/deficient in the elderly so you might consider having them tested.

Thank you Clutter


Low B12 is very common as people get older, our digestion fails to absorb it from our food. A lot of the symptoms are very similar to those caused by thyroid problems. I wish your Mum well, she is lucky to have you looking after her. Best wishes MariLiz
