<<Disclaimer: Verify this information before applying it to your situation.>> All his blood work for sprue was normal including the albumin(protein) . The doc said despite all his pooping he retains the nutrients. Maybe it is just a milk allergy??? Maybe he is still ciliac and won't show up in blood. He has an endo with a flex sig scheduleded in future. Maybe it is endocrine related? Anyone else have negative blood work and a positive endoscopy?? Dianne
