Am concerned about auto immune disorders of the endocrine and neurological systems. What does lab work of 266 on a Methylmalonic Acid, Serum test indicate? Creatanine Kinase, Total is 49. Vit B12 is 597. Had thyroid radiated due to Graves 6 years ago. Antigliadin Antibody Panel shows Gliadin Antibody IGC and Gladin Antibody IGA 15. Thank you for your consideration for my loved one.
