Question on Lab results

[annie234]

Just got my labs back I am on ERFA wondering if I need an increase? My Doctor said no increase what do you guys think? TSH 0.05/range 0.40 - 5.50 Free T4 0.7 range 0.8 - 1.8 Free T3 296 range 230 - 420. I did not take ERFA before the blood work. I am on 90mg of medicine. Thanks

Most doctors don't recognize or accept that a suppressed TSH does not automatically mean you are hyper.  Only if your FT3 and FT4 levels get too high and you develop hyper symptoms, should you be regarded as hyper.  Sally is right that TSH is often suppressed when on medication, and not just with natural thyroid meds, either.  I had a TSH of less than .05 for over 25 years while taking a full daily replacement amount of Synthroid, and still had lingering hypo symptoms. Only after learning on this Forum about the need for FT3 testing and getting my meds changed, was I able to get my FT3 level to upper part of the range.  Now I feel best ever.

Thank you both, I am feeling a little tired and cold. I hate to increase without his ok, because I will run out of medicine to soon. Sally you are right he said if I increase it would be to much medicine.

Agree with gimel.  If you are symptomatic a small increase in meds would probably be helpful.  Your doctor doesn't want to increase becuase the TSH is low.  However, TSH is often suppressed when taking the natural thyroid meds.

Actually , the answer depends on whether you are still having symptoms.  If you have symptoms, then your FT3 and FT4, which are in the lower part of their ranges, need to be adjusted, until symptoms are relieved.
