Why do I need a Kidney Biopsy? Talk to Your Kidney Doctor at FKP. 

A kidney biopsy may be done to:

  1. Diagnose a kidney problem that can’t otherwise be identified
  2. Help develop treatment plans based on the kidney’s condition
  3. Determine how quickly kidney disease is progressing
  4. Determine the extent of damage from kidney disease or another disease
  5. Evaluate how well treatment for kidney disease is working
  6. Find out why a transplanted kidney isn’t working properly

Your doctor may recommend a kidney biopsy based on the results of blood or urine tests that show:

  1. Blood in the urine (hematuria) that’s localized to the kidney
  2. Protein in the urine (proteinuria) that’s excessive, rising or accompanied by other signs of kidney disease
  3. Problems with kidney function, leading to excessive waste products in the blood
  4. Not everyone with these problems needs a kidney biopsy. The decision is based on your signs and symptoms, test results, and overall health.



Seeing blood in your urine can cause more than a little anxiety. Yet blood in urine — known medically as hematuria — isn’t always a matter for concern. Strenuous exercise can cause blood in urine, for instance. So can a number of common drugs, including aspirin.

But urinary bleeding can also indicate a serious disorder.

There are two types of blood in urine. Blood that you can see is called gross hematuria. Urinary blood that’s visible only under a microscope is known as microscopic hematuria and is found when your doctor tests your urine.

Either way, it’s important to determine the reason for the bleeding
