Im a bit confused after asking for some opinion on my thyroid test readings
THYROID STIMULATING HORMONE 1.45 mIU/L 0.27 - 4.2
FREE THYROXINE 12.8 pmol/l 12.0 - 22.0
FREE T3 6.1 pmol/L 3.1 - 6.8
Im reading that having a low T4 is bad yet T4 is the inactive form, and if its only used to be converted into T3 then why does the T4 level matter if the T3 is in range? sorry if i sound confusing.
