I went to the Doc tonight as i had been feeling extremely tired for a while now.
He looked at a previous blood test result i had done back in November andnoticed my GFR was 69. Which he considered a little on the low side, but obviously not low enough for them to contact me im guessing !!
He said at my age (50) it should be around 85 ish. but he didnt seem at all concerned and said lets do another blood test and see what it is now.
Ofcourse being the hypochondriac i am im worrying now thinking i may have something seriously wrong with my kidneys or their function. I did read that this can be reduced by past frequent urine infections, i was plagued with them through my thirties alongside a lot of cystitis bouts too.
Can anyone tell me whether that reading should be of concern to me, my Doctor didnt bother contacting me way back in November, so im thinking not.
Any advice would help please.
There are other factors to take into account when looking at whether you are in the early stages of kidney disease or not. The eGFR is just that, an estimation, and it is not the most accurate way of measuring your glomular filtration rate.
A 24hr Creatinine Clearance test, which involves collecting urine over 24hours, then having your blood drawn, is a bit more accurate, however, this way of measuring creatinine excretion can overestimate. I can feel your frustration at the seemingly intransigent nature of the medical profession. My nephrologist ordered my 24hr CrCl test and Ultra Sound, and I never heard back from him. This "no news is good news" silence does not mean that I don't have low level kidney disease; it might just be that I am too early along the disease course to matter to the specialist.
Medical specialists, I have concluded, are rather pragmatic, and so, going to see a specialist might not furnish you the answer(s) that you want at present.
Your fatigue and lowered eGFR might be connected, and maybe not. Early kidney disease might or might not present with symptoms, and if so, those symptoms might be vague and caused by other circumstances unrelated to your kidney function.
What are your risk factors? Weight? Diabetes? Blood pressure issues? An eGFR value, as yours, is not typically normal, adjusting for age and sexl. I would say-and this is my humble opinion-that at most, you are at a subclinical level of kidney disease. Hence the apparent lack of concern from your doc(s). Keep us apprised.

I went to pick them up from the surgery and the receptionist told me the Doctor had had a look and didnt call me as they were all considered within normal ranges but are they? ive been trawling th enet tonight for normal ranges and i cant get any results. If i list some can someone please help?
Serum Ferritin = 29 ug/L
GFR which im presuming IS creatinine? = 66mL/min?
ESR = 3mm/h ?
I have no idea where to find UK ranges of this sort. So does anyone know if these are within normal ranges? the Doctor didnt seem to want to see me so im presuming they are ok... HELP please
GFR is not creatinine. It is the estimated Glomerular Filtration Rate - the rate at which your kidneys filter the blood in your body. As you typed, it is in milliliters per minute. If your doc is not concerned and the majority of your levels are normal (as they appear to be) I wouldn't worry too much.
Like I said, depending on your lab and doc, anything over 60 is considered normal. Anything above 60 is also an inaccurate estimate. There isn't really an industry "standard" for what it is supposed to be based on age. Some docs have opinions, but these are not universally shared. The doc would have brought you in if there were any significant problems. Also, these are point in time tests. You want to see how it compares next year (don't forget to hydrate for the test). And there are always minor lab errors to consider too.
I am very similar to your case. I am the same age (50 in three months), and have also slightly lowered eGFR, with fatigue issues. Let me know what you find out about your fatigue, and what might be the cause.
