I'm a 63 year old woman. My GFR went from 80 to 38 over an 8 month period. I'm hoping it's an anomaly, but how long am I supposed to wait before doing another test? Or should the doctor be doing some sort of further testing now since it was just a drastic drop?
Kathy, if your eGFR was at 80 8 months ago, and this is the first repeat blood test you have had in those 8 months, then it could just be a blip, and the test should be repeated in the next few weeks. However, if you have been having continuous tests over the last 8 months that have each shown a continuing downward trend, then your GP should have referred you to a renal consultant by now for further investigations to find out the cause of such a rapid reduction. Hopefully, it is just a blip and your next test will show an improvement, otherwise do get that referral, and good luck!
Hello Kathy,
You don't say whether this is the only test you have had. if so, it ay just be an anomoly- they do happen sometimes. I;m sure that your GP would order another test for you if you asked. NICE guidelines say that a drop of 10% should mean that you get a repeat. Good luck with it!
In agreement with Mrs. O-UK Surrey... but if indeed, there is a decrease in function, you can go over meds you currently take, and see which ones impact your kidneys. Also, stop NSAIDS and drastically reduce your consumption of salt. You may seem some improvement that can stabilize where you are.
This was my first test in 8 months - just a routine test due to some meds I take. Thanks for your advice about repeating it in a few weeks - that's what I'd really like to do. So far they haven't even called me about it - just put the test result on my online patient profile.
Thanks for your response. The test was just a basic metabolic panel. I will wait a week to see if they call me, then I'll ask for a repeat test. I was surprised they put the result online; usually they call if any result raises questions before they put it online.
Thanks, TMNA. My sodium level was low, so that shouldn't be a problem.The only NSAID I take is aspirin for heart problems. I did just start a new calcium channel blocker but I can't find anything that says kidney problems/failure can be a side effect of that drug.
Kathy, now having read your further replies, if it was me reading the results like that with a very large drop in kidney function since your previous test 8 months ago and with no subsequent contact from the surgery, I would be hot-footing it to the GP for a repeat test asap. Blood pressure medications can affect kidney function and that is why routine blood tests are carried out on kidneys and liver within a few weeks of starting the medications and repeated 6-monthly or annually depending on the surgery.
Thanks so much for your replies. I decided to call the nurse and she suggested I get another test done now, so I did and it was just 3 points higher. I have made an appointment with my PCP.
Hi again, Kathy, I do hope the new appointment comes through quickly, but shame on your doctor for not having contacted you immediately that previous blood test result came through. However, stay positive - 3 points higher is going in the right direction. Good luck and do let us know how you get on.
I agree that the doctor should have called me. Unfortunately my heart doctor retired and it was a new doctor I haven't even met yet who ordered these tests. But it's already making me question whether I want him as my heart doctor.
Well at least he did request the blood test to include your kidney function, I suppose! I'm sure you'll be asking what happened after that when you eventually meet him.
Where I live, the doctor doesn't even look at my lab results until my next appointment. This is a big problem in how medicine is practiced. I have decided that from now on, I want to see my blood work results as soon as they are available so that I can discuss any abnormals with the doctor. If I don't have a follow-up appointment, then I will make one if I see anything unusual or send the doctor a fax and let her know I am concerned about that result. I don't expect my doctor(s) to be as conscientious about my health as I am.
Get yourself put on PatientView. The hospital will arrange it. I am on it and find that most of my blood results are put on there the next day. GFR takes a little longer and they don't put up TSAT. I was told there "is no interface for it" whatever that means. However, it usually very close to your transferrin result which does get put on.
I haven't seen that doctor in almost two years, so it's a good thing mine don't wait until my next appointment to look at lab results. My HMO has something that must be similar to PatientView. I can see my lab test results; that's how I know my GFR had dropped. I don't think they test for transferrin or TSAT (whatever those are). In the past the HMO has always called before posting an abnormal result.
Thanks for letting me know about Patient View. My lab makes my results available, but I have doctors that want to take the blood in their office and they use the Hospital's lab, and of course it's more convenient for me. Those results have not been available so I'll talk to the hospital about Patient View.
I saw my PCP and he thinks I probably have a kidney stone but is running lots of tests - blood (my GFR went up to 43), 24-hour urine, ultrasound. I appreciate how thorough he is.
The ultrsound should show it up. I had a stone some years ago. Luckily it can be removed quite easily usually and your GFr should improve again.
Good luck!
I've had a different test every day for the last 3 days, and now tomorrow I'm seeing a urologist for what I hope will be the last test. I don't have a kidney stone but I do have something called hydronephrosis caused by a blocked ureter. I hope the test tomorrow will show what is causing the blockage. I am really happy with my PCP and how quickly he is moving this testing along.
There is a growth blocking the ureter, but I will need a procedure to biopsy it. That can't be scheduled for almost 3 weeks. The doctor suspects cancer but thinks it will be able to be surgically removed. So I know I'll spend the next 3 weeks researching cancer. Certainly not what I expected
