I recently visited my doctor for symptoms which include:  intolerance to cold,  very cold hands and feet, poor memory, rapid heart beat that lasts only a few seconds 1-2 times a month, dizziness, lightheadedness, slight nausea, and the inablity to lose last 15 lb, no matter how much I exercise.
My doctor did a TSH test for hypothyroidism which came back as .41.  I didn't notice any tests for T3 and T4.  Should this be done also?  One more thing, the lab test showed very low RF titers.  I don't know what that is and my doctor didn't make mention of it.  Does it have any relevance?
Thank you,
Tracy

Dear Tracy
Generally, TSH is sufficient to screen for hypothyroidism. I suspect the RF stands for rheumatoid factor, and the low titers should pose no problem to you.
I hope this has been useful. Feel free to write back with further questions. Good luck.
