Hi hezzer926. It can be hard to pinpoint when an infection occurred. What is important is that you are improving on treatment. This shows you are on the right track.
Some doctors do not run the CD-57 test. According to Dr. Burrascano, the CD-57 number does not steadily increase during treatment but jumps once the infection is under control.
I would not worry about this. You are responding to treatment, so keep on keeping on!
