Hi, Dr. Andrew, I have been taking Calcitonin Salmon for many years. It seems Peptides in this drug, which treggers the development of anti-calcitonin autobody. If high autobody titers found in my body, that means loss of treatment. So, if that is the case, I shouldn t take Calcitonin Salmon. Is that Correct? I have been having every side effect on the list and I didn t know. But so far nothing is serious at this point. I think I should take a test of I have high autobody titers or not. Please answer the question. Thank you. Kyoko
