If pneumonia was found, that could explain the low HGB, as the body can "hide" iron if you are sick with a virus or bacterial infection. When my daughter was sick for a few days with a cold, her HGB went down to borderline anemic and her TSAT was way below normal. CRP and sed rates were up, too. I was worried about the CRP and sed rate so to rule out Crohn's related inflammation, they were redone in two weeks, at which point they had both settled down.
Many doctors don't realize that a B12 deficiency should be assumed whenever B12 reaches 300. B12 treatment should be started any time B12 is 400 and below. For Chronnies, such treatment should include a shot - B12 helps the body use iron, as you probably already know. B12 also regulates homocystein levels, which you probably also know.
Which supplements are you taking?
Any good endocrinologist should know that Vitamin B12 deficiency can be presumed at 300. However, it should never be below 400. Optimal B12 should be 500-600. The protocol to follow for B12 diagnosis and supplementation is decribed in the link below (the full text document is free):
Lab reports adhere to outdated guidelines and therefore might say that B12 deficiency is presumed only below 230, or 200. This means family docs and GIs are routinely led astray, thinking B12 is normal when, in fact, it can very well be deficient.
