What causes low eGFR in a patient with Epstein-Barr virus infection?

Posted on Tue, 26 May 2015
Question: I had Epstein -Barr virus over Xmas and my vitals were all off because I had a fever and was dehydrated . On a blood test it showed My glameralor filtration rate was 59 , my doctor was concerned , but due to my prior blood test he thought it was due to being sick , but he still wanted me to come back 3 months later to get a recheck , and told me if I have any other symptoms come back before then . When I went back he checked my microalbumin / creatlnine it was 30.3 , but the day before I went on a 40 mile bike ride & ran 4 miles the same day as my test ? My glameralor was back to where it usually is around 77 . I am 50 yrs old does is sound like its a problem I'm going back in a month for another test .

Brief Answer:
Sounds like no problem

Detailed Answer:
Hello,

I suppose that 59 was your 'estimated' glomerular filtration rate (eGFR). When somebody is dehydrated the eGFR may drop but in most cases (and when there is prompt treatment) no permanent damage occurs. This seems to be your case too because 77 seems OK for your age.

Regarding albumin to creatinine ratio: if 30.3 is microgram/milligram then this is fine too. If it is milligram/millimole then this is marginally OK too. In the second case, since the result would be marginal, I would advise having a 24 hour urine collection for albumin to determine whether you have albuminuria or not. Also if you've ran long distances, some protein may be found in your urine, without having any glomerular disorder, so try to avoid exercising for a couple of days before having the test.

Kind Regards!
