Hello,I am a 58 year old woman and recently I was told there there is excessive protein in my urine. For the past year and a half my creatinine level has been 1.33. My doctor recommended that I see a nephrologist to address the problem. So ,I did see one. The doctor suggested that I get a urine test done. The protein level was over 15,000- no kidding. The doctor then asked me to get a 24 hour urine collection test done. The protein level now showed 8,000. Now the doctor has advised me to get a biopsy done. Since biopsy is an invasive procedure, I am a little worried about it. Please advise as to what I should do. Please note that I have no blood pressure issues and I am not diabetic. I got an ultrasound of the kidney done in Oct. 2014 and the results were normal. That is why I am a little confused. A response from you would be appreciated.
