You will always test positive for antibodies for the rest of your life (that goes with a lot infections outside of lyme too).
It's an evolutionary adaptation. Your body will always keep antibodies out there just in case the threat presents itself again. You want your body to do this. It's how humans have survived this long.
So an antibodies test will always show positive even if are symptom free.
