My son has Eosinophilic Esophagitis and we just had blood work done because of his fatigue. His Anti-SS Dna test results were 419. Way over the range of 0-99. I was told that it could be from the EoE but I cannot find any information that leads me to this conclusion. Only that it could be an auto-immune disease. My primary wants to send him to a pediatric rheumatologist. Would a rheumatologist be able to diagnose autoimmune or if its caused by EoE?
