Albumin/Creatinine Ratio Urine
What is ACR, UACR?
The Albumin/Creatinine Ratio (ACR) or Urine Albumin/Creatinine ratio (AUCR) is advised to screen and detect early kidney diseases in people having diabetes or other risk factors like high blood pressure.
Why is ACR, UACR done?
The Albumin/Creatinine Ratio, Urine is done:
In case if a person has been recently diagnosed with type 1 diabetes
In case if a person had been diagnosed with type 1 diabetes 5 years ago to assess kidney function
In case a person has type 2 Diabetes then annual testing is required
In case if a person has high blood pressure for many years
What does ACR, UACR Measure?
The Albumin/Creatinine Ratio, Urine measures the amount of albumin present in the urine to screen for kidney disease. Albumin is a protein which is present in the blood but not in urine in properly functioning kidneys.
In early stages of kidney disease, albumin might be detected in the urine. The tests for albumin and creatinine are done on a urine sample to calculate an albumin-to-creatinine ratio (ACR). This provides a more accurate indication of the amount of albumin being released into the urine. Creatinine which is a byproduct of muscle metabolism is normally released into the urine. It is released at a constant rate, and it acts as an indicator of the urine concentration. This property of creatinine helps in an accurate measurement of albumin on a random urine sample for urine concentration. The presence of even small amounts of albumin in the urine can be an indicator of early kidney disease.
Interpreting ACR, UACR results
A high ratio indicates kidney disease. This increased ratio is an indicator of poor kidney function
Undetectable levels of albumin mean that your kidneys are functioning normally.
