Fluctuate: There is great variability among labs with this kind of test, and actual tigers fluctuate. There is little reason to test these often

ANTI-THYROID AB: THYROID PEROXIDASE ANTIBODIES (anit-TPO) IS FOUND IS THYROID DISEASE, ESPECIALLY THOSE COAUSED BY AUTO-IMMUNE (IMMUNE TO YOURSELF) DISEASE. LEVELS OF POSITIVITY CAN CHANGE WITH TIME BUT WOULD NOT EXPECT IT TO CHANGE ON A DAY TO DAY BASIS. LABS DO TESTING USING DIFFERENT SUBSTRATES ; OR SOMETIMES THERE ARE LAB ERRORS. IF THE RESULT IS IMPORTANT, HAVE IT RE-RUN. IT WILL NOT GO AWAY HOWEVER.
