It is really hard for me to give you an answer. I am doing a 6 month protocol and I just got an outbreak around day 110. I wouldn't get retested unless you go for awhile and there is no outbreak. I would also go a step further and eat trigger foods (high in arginine) and see if that causes an outbreak. If you do not get one at that point, I would get tested.
Are the tests that you are doing testing the amount of antibodies? If so, that number can fluctuate when you are having an actual outbreak as the bodies response to the disease.
