The lab's doctor has commented on some of your wife's abnormal results. You can also refer to labtestsonline.org/understa... for reasons for high and low full blood count evaluations.
B12 is good but folate is a little low. Your wife could supplement folic acid or a B Complex vitamin which will contain folic acid.
Calcium and phosphate are within range. Does your wife's GP monitor vitamin D and PTH?
*Edit: I've just seen vitD result on your second post.
