OK..I have CKD 2 ...watching it, not causing too many problems...But Last Monday I was sick. on Friday after my virus was better, I went and got lab work done. To check my potassium and such. Well the test gave me a BUN of 74 and and CREA of 2.4. So my approx GFR is 23. I had a repeat test done today, but can being sick cause that much of a rise?? And in both... I'm very fightened right now. I am still awaiting results...pls help me...

I threw up for a night( lastsunday into MOnday). And I didn't feel good all week, I was able to drink, but not eat very much.
Could it just be that??

Gracie, Hope you are feeling better. Have you gone back to the Dr. since the second blood work. What does he say about your 24 GFR? Creatine too is high? Hopefully the levels were better after your virus.
