I recently had thyroid blood test done and I'm confused. The results were:
TSH 1.180 Range 0.270-4.200
Thyroxine free 1.81 Range 0.93-1.70

My TSH was normal and the thyroxine free was a bit high. I've been on Synthroid for a long time and have not had any increases of my medicine recently. Does these readings show I'm hyperthyroid?

Thank you for asking

Slight variation with use of synthroid are fine. What matters is TSH and T3 , if they are in range then you are good to go.

You may reduce the dose of thyroxine and consult your endocrinologist to rule out any subclinical hyperthyroidism.

Take care
