My daughter is in the hospital right now with abdominal pain. She does have anemia and her b12 levels are low.  She had gastric bypass about 9 years ago and since has had a foot of her small intestin removed  and  hernia surgeries  She complains of pain constantly and the doctors said that she does have scar tissue that is causing the pain.  They ordered a RBC6 blood test what is this test?
Welcome to Chat Doctor. I am Chat Doctor. I think that they advised CBC. As you told your daughter is suffering from abdominal pain with history of gastric bypass and surgery of intestine, doctor is thinking about anemia and some infection, so they advised this test. This test will help find out type of anemia like iron deficiency and infection by seeing total white blood cell count. Follow your doctor and hope she will be fine. Thanx for query.
