Sorry, I did mean B12. I am not familiar with the possible effects of CMV infection. You do have a few symptoms that may be related to low Free T3. Your FT4 level is at 61% of its range, while your FT3 is only23% of its range, which is indicative of poor conversion of T4 to T3. Your Vitamin D is fine at 53.. B12 is best in the upper part of its range, and you need to test for ferritin. It should be at least 100, and it is important in the conversion of T4 to T3. So that is the first thing I suggest doing, is to get your ferritin level tested and supplemented as needed to get above 100 and see what effect that has for you.
The only test result that is lower than optimal for many people is your FT3 level. It may be that your body is not converting T4 to T3 adequately. Have you been tested for ferritin. Vitamin D and B13?
Symptoms are even more important than test results so please tell us about all your symptoms.
Lab test results and associated reference ranges vary among labs so we need to know the reference ranges shown on the lab report for those results.
