Your index value is in the low positive range for sure, and I would guess that there is an 85-90% chance, or better, that this is a false positive result. But the western blot is by far the most accurate test and if UW can get you the kit, then I think you should do it for greater clarity. A slightly higher score is not a big deal. And I could definitely help you obtain the blot – we would need to do a video conference to get this accomplished.
