Please could someone let me know what they think of these results from a thyroid perspective?



The only thyroid result is TSH 2.23 which indicates your thyroid is beginning to struggle. NHS won't diagnose primary hypothyroidism until TSH is over 4.50. Testing TSH only will exclude a diagnosis of secondary/central hypothyroidism.

Oestradiol and Urate have been flagged as low and prolactin as high. If you Google "Oestradiol low", "prolactin high" etc. you should get explanations.

HbA1c 31 is negative for diabetes.


High prolactin may be linked to being hypothyroid

(Google high prolactin & hypothyroid)

Suggest you ask GP to test Thyroid antibodies, vitamin D, folate, ferritin and B12

Also test TSH at same time as FT3 and FT4

Quite likely they won't be keen to do so

You can get full private test


Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw

All thyroid tests should be done as early as possible in morning and fasting

What symptoms do you have that prompted testing
