Anybody in the health care field able to help me understand these blood results?

Co2 levels have consistently been on the higher end for a few years. And hgb levels consistently low for a few years. None of these are at any crazy levels but are just a bit abnormal. I have been complaining about my fatigue to my rheumatologist and she says nothing about the blood work and the two numbers that have been off for a few years. I am just trying to get to the bottom of it. My doctor is currently out of the office for a week so won’t get an answer right away. Just trying to see if anyone here can shed some light on this. I have Pics of the graphs of the results on my phone. Thanks! -josh
