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.

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.

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