I have undergone a treatment for high blood pressure and the reason for that is tracked down to CKD. My creatinine is:2.7 and GFR is 30 and K is 5.4. My doctor is asking me for a kidney biopsy to narrow down the issue and based on the result treatment will start. So If you can suggest me what should I do .If I have to do the biopsy it there is some other options which I have. Thanks in Advance sir.
