A member asked:
Hi, my free ft4 is at higher end of normal at 20 (range 12-22 pmol/l) and my total t3 is at lower end of normal at 1,62 (range 1,3-3,1 nmol/l). could that implicate under-conversion of t4 to t3?
A doctor has provided 1 answer
T3 is converted to T4, not the other way around. Your levels are appropriate.
