Making sense of lab results

Hello everyone,

I am new to this website, but would greatly appreciate any thoughts you have on my recent lab results. I had a TT in August 2013 for papillary thyroid cancer and I went through the initial RAI treatment after surgery and a follow up body scan in September 2014. Apparently, everything is fine now, but I struggle with total fatigue. I just want to my endo on Friday of last week and have the following lab results that I am eagerly waiting for my doctor to interpret for me. Any thoughts on what you see? Thank you in advance for your insight.
