Does anyone know what medical conditions (other than Celiac) are associated with high Tissue Transglutaminase, IGG levels? Mine were 25 and 33, (Negative = <7), two different labs. My IGA level is <3, (negative = <5) on both labs. I tested negative for Celiac via intestinal biopsy.
What else can cause high IGG levels? I also have Primary Hyperaldosteronism, Chronic Epstein Barr Virus which reactivates often, have tested positive for Mycoplasma Pneumoniae, and HHV6. I have chronic migraines and very low energy. Headaches and energy issues are so critical that I spend many days in bed. Just had a spinal tap, ordered by the neurologist & waiting on results. Anyway, doctors don't seem concerned about the HIGH TTG Antibody, IGG. I'm thinking it's not a good thing and would appreciate any feedback. When I search this topic I only see 'Celiac' articles. Thank you!
