I am very concerned. Out of nowhere,my Creatinine and GFR counts are way high. I looked on line and it looks like significant kidney failure. Did a retest this morning and will meet with my regular family doc to see what this all means. Now and then I get a very high count on something that has always been normal. Hope this is one of those occasions. But, in the meantime, I am concerned and will likely have to wait till Monday for the results. This will mean a long weekend
