Respiratory infection --> creatinine levels

[GoingThere]

Another question from me. For the last 14 days I'm struggling with leucopenia. I got 2 shots to rise WBC on Monday and Tuesday. On Monday I started to cough and this cough is getting uglier day by day. CRP shows nothing, only creat levels are again up for 0.27 in 5 days.
Is it possible that respiratory infection or any other infections cause creatinine levels to rise? You know: He who has been bitten by a snake fears a decayed rope.

I suspect it's degydration making your creatinine go up. I can never manage to drink enough when I'm sick.

Yes, yes a respiratory infection can create a rise in your creatinine.

Here is an excerpt from The Foundation for IgA Nephropathy
Serum creatinine.

This is obtained from a simple blood test. Normally, during the course of follow-up, serum creatinine will be checked frequently - that is, whenever blood work is done. Serum creatinine is the major component in the various equations used to estimate GFR, and as a patient, it is what you will use most in tracking how your kidney function is doing.  Patients should keep in mind that serum creatinine will vary a little, up and down, from one test to another, and therefore, they should not attach too much importance to these apparent "improvements" or "worsening" of kidney function. In addition to an error margin of about 10%, serum creatinine results may vary depending on which lab method was used (a 10-20% variation is possible), and being dehydrated will increase it (usually with a disproportionate rise in urea or BUN). It may also rise during "flare-ups" which cause a bit of acute renal insufficiency, and other illnesses such as colds, flus, etc. People on our Yahoo Groups-based email support group often ask whether exercise or eating more protein affects it. The answer is that serum creatinine will not be significantly affected by exercise or how much protein one eats, but it will vary to some extent. The important thing is what the general trend is over time. Please note that serum creatinine does not rise above normal until creatinine clearance has already declined to half of normal (50% kidney function). So, by the time a blood test picks up an elevated serum creatinine, you probably have already lost half of your normal kidney function.

Take it at face value.
