Reply To: Question and Advice about Low Positive IGG after 7.5 weeks

[Terri Warren]

Eight weeks post exposure is not enough time for an accurate western blot result, unless the results are positive, which you could then rely upon. If you want the most accurate test, I would recommend waiting 16 weeks from the exposure, which is what the University of Washington includes on their test report as their recommendation as well. However, if you want to do one now and one later, people do that. If you are negative now, then there is about a 70% chance you will stay that way.
