Hi, my sisters blood test results have come in, Im wandering what to advise her to do?
tsh 0.19 (0.35 to 4.5)
FT4 20 (12-22)
FT3 3.7 ( 3.1 - 6.8)
She is suffering from tiredness especially in the evenings. The doctor advised her to lower her dose from 100 mcg thyroxine to 88mcg. based on the tsh and ft4 results. I suggest she get her ft3 tested privately before she did it and the result came as 3.7 which is very low. She is taking vit D supplements and well woman vitamins.
Do you think she should reduce her dose as the doctor suggested or look elsewhere to improve her Ft3 result.
