Low Transferrin/Iron Binding Capacity, fatigue, weirdly high B12, is this ok?
47M. There seems to be a trend of RBC going down slowly, B12 is going up, Vitamin D was low but now it's good (25-Hydroxy Vitamin - D got cut off, the low numbers are older and not shown), transferrin is a bit low, some of the other ones are a bit low but not horrible. B12 seems to be high but the lab dropped the high end of the range for some reason. I haven't seen a hematologist, none of my doctors see a problem here, in fact one said that low transferrin was a good thing.. All my liver/kidney tests are good so I don't think that could be a cause of low transferrin.
I had some relative with pernicious anemia, but I have high B12 so it's not that and I have other autoimmune diseases. The fatigue may be unrelated to the blood tests, it could be the other diseases or some new possible neurological diagnosis that I might get confirmation on sometime this decade/century. Symptom wise, I'm tired all the time, I fall asleep sometimes while sitting down, standing, talking, using tools, etc. Usually it's just half a second or so at a time. I also think I get a bit of shortness of breath while running/doing something intense (it's not terrible), but I don't do a lot of running anymore.
Edit: I forgot to add one more symptom. My fingernails/toe nails have gotten thinner and split often, length wise along the vertical ridges and my thumb nails are going somewhat concave. So far I've trimmed them before the split gets too far. Not quite as crazy as some of the photos I've seen online but it didn't used to look like that.
