Hi jersey. I have no clue why she wouldn't check for blood. However, I'm going to a highly recommended gastroenterologist for 1st appt on Feb 27th. I'm saving these questions for him. Supposedly, I'm being referred to immunologist for IgA deficiency, and IgM. I didn't know that I had this issue and only just found out it was discovered in labwork 5 yrs ago. IgA result recently was 26. Ugh. Thx so much for caring and encouraging me. Hugs
