I would appreciate it if someone can help me interpret some test results. I have hypothyroidism & am on levothyroxine (100 mcg daily at present) but am feeling so low in energy I'm preparing to go back to my GP better prepared & researched than before. I'm looking at some of my old blood test results and am finding myself confused.
On 20.03.2013 my result sheet shows "Thyroid peroxidase antibody level 728" but no range or abnormal test marker is shown. It goes on "Ser tiss transglutaminase lev (c) Text: Negative for IgG and IgA tissue transglutaminase antibodies". Does this mean I have Hashimoto's or not?
On 15.01.2014 my Serum T4 level was 12.8 n/mol/1 (range 70-140).
On 28.04.2014 my results were Serum free T4 level 17.1 (range 9-23); Serum TSH level 0.01 (range 0.3-4.2); Serum T4 level 12.8 (range 70-140).
I understand the last two paragraphs but not the thyroid peroxidase antibody one.
