Hi I have been looking through a summary of my medical records - some anomalies - missing years, odd recordings, misprints - but, that aside - It seems that back in 1982 I had thyroid antibodies. (Been convinced that I have had Hashi's all along) But subsequent tests show 'neg'. No figures as only summary, asking to see records. But confused, can antibodies 'disappear'? Obvious signs of HyoT and was diagnosed about 10 years later. Does that mean I am considered to have 'Hashi's or not? Notes are vague.
