I had a recent set of bloods done and I went online to check my results and seen the eFGR result there when previously it had never been recorded.............or at least never sent to my GP, where the online database gets its information..........

Anyway, what are peoples experience with this.............

my reading is low and from a Google, says stage 3 kidney disease............

no doctors have been in touch yet..........

should I make contact with someone..........?
 
hang on..I would ring tomorrow and ask what your eGFR is. it should be over 60 and no/little protein in your wee ..some labs test to over 90
you can use an online calc with components from your test...which is the e for estimated in the GFR
if you put your numbers up that you are using ..someone may be able to look at it for you

it uses a protein that is usually stable ..unless you are losing weight
 
eGFR is estimated GFR calculated by the abbreviated MDRD equation : 186 x (Creat / 88.4)-1.154 x (Age)-0.203 x (0.742 if female) x (1.210 if black)
 
this simple calc said your ok..where did you get the eGFR of 59 from?
Cystatin C is also used


http://egfrcalc.renal.org/

GFR = 108 ml/min/1.73m2

>90 = Normal GFR

The 90% confidence interval for this estimate is: 76-140 ml/min/1.73m2

Calculated for creatinine = 74, age = 40, sex = male, race = other

Agree with Jack I was just going to give these.
http://www.nuh.nhs.uk/healthcare-pr...-calculators/creatinine-clearance-calculator/
http://egfrcalc.renal.org/
The first takes into account your weight using one formula to give the estimated creatinine clearance, the second doesn't use weight but seems to be the one that seems used by by labs in the UK
(my lab report uses the first)
Any estimate I do with weight and age comes far above 59
A lab calculated one is supposed to be more accurate but that seems very different

Do you have the urine albumin to creatine (ie microalbuminuria ) test because that shows if your kidneys are spilling protein.http://www.patient.co.uk/doctor/Microalbuminuria.htm

the eGFR figure I have is from a website [MyDiabetes, MyWay], along side my other readings, so it must have been input from someone..........

is it just a calculation..........?

I am not aware of the results of my urine test yet.....
 
I've had 4 blood tests this year with an eGFR, and none of them corresponds to what the calculation in @phoenix 's link says.
 
@Bluetit1802 which one?
The first one doesn't give the result as an egfr but
like this
Calculated creatinine clearance 132.97(ml/min
(that's for a 40 year old male weighing 80kg)
the second with the same parameters minus weight gives
GFR = 108 ml/min/1.73m2> 90 = Normal GFR
The 90% confidence interval for this estimate is: 76-140 ml/min/1.73m2
Calculated for creatinine = 74, age = 40, sex = male, race = other
So basically a slightly higher estimate but within the same confidence interval. Both would be considered fine.If you google it you find there is some controversy about which equation should be used when.
Just double checked and both calculators have an input in micromoles/litre

The second one also gives the caveat about local labs giving differing results
If you have an eGFR value calculated by a local laboratory, use that. It is likely to be more accurate than this calculator, which cannot take into account local variations in creatinine measurements

edit at 66kg the two calculators are about the same

Thanks. Mine are calculated by the lab when I have my blood tests. The figures for this year are 68, 68, 64 and 79. No comments made by GP. I did ask her on one occasion and she said it's just my age (66) bringing them lower as all other kidney functions are within normal range..

My eGFR has been fluctuating between 60 & 70 for at least 10 years. About 6 years ago my Dr mentioned that they were watching it & looked back a few years & from the first reported measurement it was below 70.

I suggest you ask your Dr if there has been a trend over the last few years. In any case, without kidney disease symptoms, 59 is not cause for worry.

I think it's a typo, going by your creatinine, you are more than 90 and it doesn't get better than that..as per the second site


I get 108 with the first site with weight 105kg and 61 age
and my blood test result is 75 which is the same as the second site with a creatinine level of 94 without weight
also I flux from 90-75 because of weight loss, I think
 
You have all been very reassuring, thank you.....

Will see what my doctor says.....

There is no urine test result up, if there was protein would that cause a 59

Do you get the Balance magazine from Diabetes UK? There's a feature in the latest edition (dated November-December Issue No 261) where they explain the test involved in checking for Diabetic Nephropathy.
 
I've been in the 45 -48 -area mid Stage 3 (Stage 3 goes from eGFR of 30 -59) for years now without a rapid decline. The Dr will make sure there hasn't been a rapid decline in kidney function. I take an ACE inhibitor that's supposed to help protect kidney function plus keep my blood pressure and other risk factors under control as much as I can. My clinic just keep an eye on the result as I've also got micro albumenuria - small levels of protein being excreted in my urine. Stage 3 seems to be managed by being aware of it, perhaps prescribing an ACE inhibitor and checking for protein in the urine.
 
Thanks, already on lsinopril......

Hopefully hear back tomorrow for a chat about it.....

Time to pull the finger out regardless.....
 
I heard back from a nurse who said that the way the eGFR is reported is that if it is 59ml/min or over, then the figure on the sheet will read 59, even though its probably higher than that.........

so good news in a way, going to get the consultant to confirm......

its been a scary few days, so still highly motivated to lose some weight and get the BP down.......
 
That's good news, so in other words if you are in the bracket of 60 or above and have no other kidney problems like spilling urine, it is a normal result.
Why don't they make it clear with>59 and save people the worry.
 
I'm on Ramipril 5mg daily due to a albumin/creatine level of 35 but my eGFR is >60 which normal. The whole issue of Diabetic Nephropathy is a bit confusing to the lay person, which measurements are good or bad etc. All I can say Novorapidboi is that you Consultant may put you on an ACE inhibitor to protect your kidneys. Hope this helps
