My son had the bulls eye rash a few years ago and they automatically put him on antibiotics, didn't even test him. He never had any symptoms after that. I have heard that the test can have a false negative so some doctors prefer just to put them on the meds just in case the test is wrong. What was the reason for having the test done? did he have a rash? Try not to worry too much, I am sure he will be fine. :)
