Then I will give you reassurance! I think your risk is incredibly low if not non-existent.
The only reason I would suggest a western blot is to provide you with even more reassurance. My opinion is the same as Lisa’s. From a science point of view, you don’t need a western blot. If a western blot will let you stop worrying about this then do it.
There are no false positives on the western blot. My only concern would be an indeterminate western blot; a western blot that doesn’t give a complete negative or positive result, something in between. It happens but not often.
Also, it would be interesting to look at your actual test results. Two equivocal results would be really unusual. Are you sure?
