I have concerns about my labs. I follow them very closely and keep a spreadsheet of everything. My GFR is declining again and my creatinine is up and down as well. There is a test my doctor ordered that I have never seen before. Pro+Creatu (random). I have seen it separated but not under this grouping. My numbers are off the chart. Has anyone seen this? Should I be concerned? Also, in determining GFR, would the lab be more accurate or the calculation you do online through a site like the National Kidney Foundation? The reason I ask is the lab states my GFR is 36, but the calculations show 32, which is much more dangerous.
My question is two part. How accurate are the labs in determining GFR? I did several online ones and my GFR was 32, but my lab is saying 36. Also, my doctor ordered a different test than usual and I am concerned about the outcome, should I be?
