"normal blood results"

just got my latest blood results which surgery says is normal.  T3 1.2   T4 13.00  TSH 3.7

Am I right in thinking my tsh too high  my t3 is too low and my t4 is in range but on the low end

please can someone give me their comments as I have requested the doc to call me back in 30 mins to put me on a higher dos of lev (50 at the moment)

What are the ranges for T4 and T3?


t 4  - 9 - 21

t3 0.9  - 2.4



You are undermedicated.  Most people will feel comfortable with TSH just above or below 1.0 with FT4 >18 and FT3 >2.0.
