I am currently taking 150mg thyroxine, I have taken a higher dose in the past which didn't make any difference. The following results are from last December.
Vitamin b12 is 250pg/ml. Range 190-660pg/ml
Serum folate is 5.5ug/l. Range 4.60-18.70ug/l
Tsh level is 3.31mu/l. Range 0.30-420mu/l
Serum ferritin is 89ug/l. Range 20-300.00ug/l
My G.P says all my results are normal but I would like other opinions please. Thanks in advance.
