Testing plays a crucial role in diagnosing and managing diabetic kidney disease. Learn about the key tests and what they reveal about your kidney health.

The Importance of Albuminuria Testing
Albuminuria tests measure the amount of albumin, a protein, in your urine. High levels indicate kidney damage. This test helps detect kidney disease early, allowing for timely management to prevent further damage.
Understanding GFR Measurements
The glomerular filtration rate (GFR) measures how well your kidneys filter waste. Lower GFR indicates declining kidney function. Regular monitoring of GFR helps track the progression of kidney disease and adjust treatment plans accordingly.

When to Consider a Kidney Biopsy
In some cases, a kidney biopsy is needed to confirm a diagnosis. This involves examining a small piece of kidney tissue under a microscope. It's usually recommended if other kidney diseases are suspected or when test results are unclear.
Frequently Asked Questions
High albumin levels in urine indicate kidney damage.
GFR measures kidney filtering ability; lower GFR means reduced function.
No, a biopsy is only needed if other diseases are suspected.
The Bottom Line
Regular testing is essential in managing diabetic kidney disease and protecting your kidney health.
