I wrote not long ago with test results with TSH at 1.69 a year ago, a couple of mos. ago at 2.75 and at present 2.3. My FT4 a year ago was .99, a couple of mos ago .74(L) (.77 - 1.8) and at present Ft4 1.34. When you saw that my Ft4 was .74 you said I was clearly hypo. Well, the doctor took some more tests at above is the result. Now, my Ft4 is 1.34 normal. Does the Ft4 fluctuate this much? I still have many many symptoms of hypo. I was very disappointed when he told me the results thinking for sure I was hypo.
Fluctuating levels of thyroid antibodies can cause your TSH, T3 and T4 to all fluctuate.
Right now, I would watch your levels closely and see what happens over the next few months. It would warrant having TPO and Thyroglobulin antibodies checked.
TPO antibodies attack the process that makes thyroid hormones in your thyroid gland and can cause levels to drop.
Thyroglobulin antibodies attack the protein that binds thyroid hormones in your blood and within the thyroid gland, causing T4 to be released and in so doing, can cause a rise in Free T4, sometimes very quickly.

Thank you Meep. The Doctor also wanted me to take a Glucose Tolerance Test and that came back weird. My fasting glucose was 1.03 and an hour after I drank the glucose, it was up to 269 and then dropped to 110 the next and down to 57 the third hour. Now I just don't know what to think. The doctor thinks I am potentially diabetic and could cause some of my symptoms. But I have read nowhere that diabetes causes feet and hands to ache, muscle cramps, orange eyelids, swollen tongue, hair breaking, etc.
Meep, follow up lab tests
