Do you know what the supplemental test was? The reflex test just means that they automatically run another test when you fall between a 1.0 and a 3.5, as these can be false positives.
If you can find out what that test was, I can help answer more. If it's a Biokit, and it's negative, you're definitely negative. If it's another IgG test (was your original test an IgG or IgM?), then you should maybe get the WB.
Do you have the actual test results?
Would you know if quest diagnostics have this supplemental reflex test? Or where I can find the western blot test ? Can I just go to quest and ask for it ?
