newuke Those results don't confirm Hashi's. However, one negative result doesn't rule it out. You'd need a few over a period of time to come back negative to say for certain.
If you do have Hashi's, the nature of the beast is that the antibodies fluctuate causing fluctuations in symptoms and test results. It could very well be that up to now you've only ever had a test when the antibodies were low. You need to try and catch them when they're high and attacking.
I was original on 25mcg, after 2 months went hyper. took me off levo.
Did you have thyroid tests at this time? If TSH had become suppressed and FT3/FT4 high or over range, this would suggest Hashi's and testing antibodies at that time may have shown them over range.
Also, what antibodies have been tested? There are two types - Thyroid Peroxidase (TPO) and Thyroglobulin (TG). TPO is rarely done on the NHS and TG almost never. If you've only been tested for TPO, this can be negative but you could be positive for TG and that would confirm Hashi's.
High B.P. & racing pulse. GP reduced levo to 25mcg & had GP bloods done.
TSH 6 this time, so GP upped levo to 75mcg.
Was just TSH done that time? It certainly does sound like Hashi's could be at the bottom of this. Hash's is a see-saw!
As Scazzoh has said, you could be sensitive to the fillers in your brand of Levo. Which brand are you using? I would ask to try a different brand.
Be aware that some people have had a bad reaction to Teva. Something to bear in mind if you start feeling unwell or have unusual symptoms once you change over to that brand. If you do, ask pharmacy to change you back to Wockhardt or cut the 50mcg Actavis in half.
