Hi all just got the rest of my results back. All good and within lab range yet my egfr is low for the second time at 76. 83 a year ago. But next to this it states 0 stage ckd. I have done some reading and it seems you should not eat meat 12 hours before test or exercise for 2 days before test and I did both. My hba1c was normal. In the last year since been told t2 have lost 4 stone and taken exercise very seriously. Got a personal trainer with weights and workouts most days. Is it the exercise affecting my ever or my LCHF diet
I can't comment on whether or not food or exercise affects the reading, but I can say I have never been advised to avoid either, in advance of my monthly tests. Don't forget that the e, in eGFR, stands for estimated, and so it can vary for numerous reasons. The calculation used can vary across labs and is influenced by numerous factors including age, so as that has increased since your last test, could in fact be one simple reason for a different reading.
Your eGFR is great!! Anything about 60 is good and they normally just keep an eye on it at 60. The e stands for estimated but is only ever a few numbers out either side .
Mine at last check was 30 so I have bi weekly blood tests to check it .
Yes, this is an estimated number, and part of the calculation is the person's age. The older you get, the lower the number will be. The standard used to be over 60. A few years ago they moved the goal posts and it is now over 90. There is nothing to worry about unless your other kidney functions are abnormal or creeping towards abnormal
Thank you all I've been really worried because the nurse at gp clinic commented last year that 83 egfr was too low so when I got a 76 egfr this week my heart sank.
Yes, you're quite right, latest NICE guidelines for CKD suggest fasting of 12 hours for renal function tests. The urea and serum creatinine, along with urinary ACR are important too. As @Bluetit1802 posts, >90 is now accepted as cut off. There is a considerable span for staging CKD.
NICE CKD and http://www.nhs.uk/Conditions/Kidney-disease-chronic/Pages/Diagnosis.aspx provide good reading.
Mine said stage 0. Also really annoying that in the last year I have lost 4 stone and now have high cholesterol at 5.9. Normal before weight loss. Typical
I am at stage 5 (eGFR of 10), although it went up to 11 on the last test. When mine dropped down to the 30's, I was advised that steadying my BG (and avoiding high's) and lowering blood pressure would help to a point.
eGFR test measures creatinine levels, which are a breakdown of muscle mass. This is why you need to fast, though it should only be meat products that you really need to avoid.
midnight rider has it. Also it is worked out on average body weight, they need to input your weight if you are outside the normal range. Working out with heavy weights will increase creatinine as will taking creatine (as I do) which also negatively affects the estimate
