I had an exposure in 2011 and I took three
hiv tests tridot 1 and w western blot 1 and 2 and pcr hiv 1 . All were negative. I might have had tablets that would have had biotin. I recently read that biotin interferes with tests that uses biotin streptavidin in FDA website and many doctors in other sites saying the same . Does tridot western blot use Biotin streptavidin in its mechanism? I don't know what tablets I took before the test , I have a doubt I took coenzyme R but I'm not sure . Am i negative or do I need to repeat tests.
