When should I re-test for Tickborne diseases?

The need for re-testing Tickborne infections is highly individualized depending on the provider's approach to treatment, what they are hoping to gauge with repeat testing, and the specific test results. In other words, there is no 'one size fits all' to this question for chronic or persistent Lyme. However, since treatment courses in chronic Lyme tend to be long term affairs, a longer interval between testing may be more helpful than a shorter interval.
