What are the reference ranges for the FT3 and FT4?  These vary from lab to lab, so must come from your own report.

Yes, I understand those are your current levels; however, we need to know the reference ranges used by your lab.  This should be listed on your lab report; often parenthesis beside the lab result or in a separate column.

That's what we needed.  Thank you.  While your TSH is high, your FT3 and FT4 are actually "in" the normal range, though quite low in their ranges.  

I'm not a doctor, so I can't tell what dose to take, but it does appear that you could use an increase in your med.  You could try the next higher dose for a few weeks, then retest to see if your levels come up, and your TSH goes down.  

Many of us feel best when our FT3 is in the upper 1/3 of its range and FT4 is in the upper 1/2 of its range.  What, if any, symptoms do you have?  Symptom relief is most important, regardless of the lab results, so FT3 and FT4 should be adjusted to alleviate symptoms.
