Hugely varying eGFR results.

[Rafion]

Here are my eGFR and some other results spread over some 9 months:

1. 13 September 2018

eGFR - 70, BUN - 18, Creatinine - 1.09. HbA1c - 6.2

2. 13 March 2019

eGFR - 54, BUN - 11.87, Creatinine - 1.34, HbA1c - 6.6

3. 17 March 2019

Creatinine - 1.14, HbA1c - 6.1

4. 22 March 2019

Creatinine - 1.04, HbA1c - 6.3

5. 05 may 2019

eGFR - 90.9, Creatinine - 1.07

How is it possible for eCFR to fluctuate so widely? These 5 tests were done at 3 different labs.

Hi Rafion

GFR fluctuate, u r numbers are within the range nothing to worry.

Why have u undergone so many test?

You are perfectly right - eGFR fluctuates. I was worried when my eGFR dropped to 54 which indicated mild to moderate kidney disease - this test was with Thyrocare (13 March 2019). I realised then after some internet research that I had been quite dehydrated that day as I had travelled around a bit on my two-wheeler on a very hot day. On March 22 I got the test done again at the Indian Institute of Diabetes and my eGFR was 70.98. I am sorry I missed including this figure in my original post. I was greatly relieved but to reconfirm I did another test at Hindlabs which showed 90.98 which is unbelievable. So I think my true eGFR is around 70.

No, my doctor does not know about the tests. I panicked when the value dropped to 54 and I did all the other tests on my own. I am 68 and live alone with chronic T2D and high BP and was worried. I am glad it was a false alarm.

Thanks for your response.
