My 21 year old son had just had his bloods checked and the results are as follows
Serum TSH . 3.69. (0.35 - 5.00)
Free T4 . 15 (9.00 - 22.00)
Recommendation by lab is to take on current dose of thyroxine 100mg
I'm still struggling to interprete results but am I correct in thinking his TSH should be lower and his FT4 should be higher if so should the dose not be changed ?
