@pleinster . Your point about creatinine levels being raised due to protein (even a bit of meat) is interesting.
Whilst my kidney functions have always been excellent ( eGFR and creatinine) I have had 2 tests since diagnosis when the creatinine levels were higher than usual for me - and these tests are the only two I've had that were not fasting and done in the afternoon, so presumably this was due to what I had eaten for breakfast and lunch. Every other test (and there have been many) have been fasting with the creatinine levels a lot lower.
Hi @pleinster .Thankyou for your reassuring reply.Im beginning to understand the science of it better.I had several IVP tests after my son was born and continued to be checked for ten or so years.Id put it all out of my mind and moved on,so I panicked a wee bit when I saw my results.My creatinine levels have also risen so I'll ask about that.Hopefully it's just a blip.Sometimes I wish I had an A level in biology then I'd grasp the science more quickly.I don't discuss these details with my grown up children as they tend to worry!
I'm sure your own slightly elevated levels will indeed be down to food/drink before a test, particularly if other tests have been excellent and you are not talking about a figure above 150.
@Bluetit1802 This is very interesting,I'm learning all the time,Thankyou!Ive got a HbA1c next week and then a GP appointment.Im considering fasting before this test.I guess I may be concerned for no reason.In the past I have just accepted advice,meds etc without too many questions,trusted HPs,kept my head down and got on with life.(That's my generation,not having the Internet to get more information!!)To be honest I've had excellent care at critical times.Just recently a serious error was made,so I'm not quite so trusting!
@pleinster Hi,the last three tests the levels were 70,63,96.These are usually taken around 11am and are none fasting.
Hi. If these are indeed blood creatinine levels they are all perfectly normal ! The "normal" range is between 60 and 110 mmols per litre. I would not even consider 130 to be "high". I hope that reassures you.
Is it different for men and women? My lab standard range is 46 to 92. As @Glenmac seems to have her print outs/on-line stuff, she should be able to see what her lab standard range is.
My latest was eGFR of 50
also
Serum creatinine level 128 umol/L [70.0 - 120.0]
Above high reference limit
My eGFR just keeps going down previously was 63.
Thanks @pleinster that's reassuring only thing is eFGR has now been low over two or three years so is chronic not an acute change am going to ask doc if he can take me off Aspirin and prescribe something else and I have been taking Metformin not to control blood sugars but to suppress apatite so am going to discontinue that and see if it helps.
I think your plan to drop Metformin is excellent. It shouldn't be prescribed when there are kidney issues. I'm sure NICE mentions this somewhere.
was told Metformin generally avoided with renal patients.
This is 2016 guidance is from the European Medicines Agency (I'm not sure if this guidance has been adopted by NICE):
Up to now, metformin medicines were not recommended for patients with moderate to severe
reduction of kidney function. This recommendation has now changed to allow their use in patients
with moderately reduced kidney function (GFR=30–59 ml/min). The dose of metformin should be
adapted depending on the patient’s kidney function. These medicines should still not be used in
patients with severely reduced kidney function (GFR less than 30 ml/min).

Absolutely, @pleinster you have to be so careful with the kidneys. I just added this info to this thread as it was a change that was publicized last year. The FDA in the US approved it for a lower eGFR as well. However, in the presence of kidney disease, or after a transplant like yourself, your renal specialist is, and should only be, the go to person on this.. Still, we are all variations on a theme and I would never totally disregard medical advice on my kidneys.
