My family doctor mentioned for years that my blood tests show that I have slightly enlarged red blood cells. But, he never tried to find out why - I guess it wasn't out of range enough. Recently I changed GP doctors and the new one also ran a ferritin test [I think, first I have ever had done] and discovered that my ferritin level is around 500+ which is double what the lab says is in the normal range. So, she sent me to a hematologist who ran more blood tests. Then, the hemo sent me to a GI-IBD specialist because, he says in my case, it is a marker for inflammation. I have a history of digestive problems that has never been fully diagnosed + plus an ER visit with partial bowel obstruction. So, now scheduled for upper and lower scopes + biopsies in October [possibly followed by a pill cam]. Anyone else have high ferritin and enlarged red blood cells as part of your symptoms for Crohns?
