@nycdave7 After many years of testing I no longer get excited about an anomaly like your creatinine. Sometimes it happens. There may be many reasons, the most likely (in my opinion) - lab error (mislabeled or entered to wrong patient account). For example, if the lab entered data manually using a numerical patient ID system, you could have been assigned the creatinine from another patient easily by a typo or transposition of numbers. My physicians and I are more concerned with trending and constantly compare my results to see that I remain on trend. That said, with an anomaly such as this my labs would be re-run in a month to assure that it was an anomaly and not a major event and permanent change in my status. Also, if you are already seeing a nephrologist, I see no need to seek out a urologist for your kidney issues. Good luck.
