I have one more quick question.....I posted earlier as my husband is still in diagnosis limbo for crohns. Initial bloods and biopsies were negative for crohns (biopsies from colonoscopy and EGD). We called another GI for a second opinion today as his current GI is very puzzled. The medical assistant for the new GI said that negative biopsies positively rule out crohns. We had a Prometheus test today and he was started on Budenoside because the current GI still is leaning towards Crohns (symptoms--duodenal ulcers, friability, severe anemia). I am at a loss! Does a negative biopsy positively rule out crohns? So frustrated with this process..... Thanks for reading. He does not want to do a capsule endoscopy until we have tried Budenoside and repeated scope in 8 weeks. Please help!
