About this biomarker
UACR compares the amount of albumin in urine with the amount of creatinine in the same sample. It is used to detect protein leakage that may signal kidney damage.
Why it matters
It is a key marker used with eGFR to assess kidney health.
What lower levels may suggest
Lower UACR generally suggests less albumin leakage into the urine.
What higher levels may suggest
High UACR suggests increased urine albumin loss, which can be a sign of kidney damage.
Common tests
Urine albumin-to-creatinine ratio, spot urine microalbumin/creatinine ratio
