answer:Every test has various ranges – acceptable levels, etc. Maybe it is up as compared to your previous appointment, but not to the level where he would be worried (or it is medically necessary to do something). I had that issue with my PSA (prostate) last year; my level was up compared to 2014, but not in any way out of the range of ‘normal’. Bottom line, there may be nothing to ‘cure’ at this point. For all you know, the level may go down in 6 months – it might be a fluke, or a lab anomaly, or maybe you ate something different last week. Don’t go looking for trouble.
