You absolutely need a western blot. This is the CDC guidance on people who obtain low positives. You can work with your own provider on this with the University of Washington or I can order this for you. If you want to work with me, you’ll need to do a video conference with me to establish a relationship and I can get a good history and consent to order the test. You can make that appointment at the home page of this website, if you need my help. I think since the confirmatory test was negative, you have an excellent chance of a negative result on the blot.
