<<Disclaimer: Verify this information before applying it to your situation.>> My blood test results came back negative too. Thus, my biopsy was cancelled. My parents are sure that I responded to the gluten-free diet as a child, and they believe I would have died of malnutrition without it. I also just found out that my bone density is quite poor for my age (statistically signficantly below normal). I am only 34, and have the hip bones of a 70 yr old woman. My rheumatologist ordered the test because she said that many people with malabsorption have low bone density. Yeah, I am totally confused about whether or not I have Celiac. Unfortunately, it is taking forever to get my GI to get to the bottom of this...and I don't think he is too interested since my blood test came back negative and becuase I am not anemic. -Susan
