Low Urine albumin-creatinine ratio (UACR): what it means
A Urine albumin-creatinine ratio (UACR) result below the normal range is considered low. Here is what a reduced Urine albumin-creatinine ratio (UACR) can point to, and when it is worth discussing with a doctor.
Reference range: <30 mg/g normal; 30–300 = moderately increased (early kidney damage); >300 = severely increased. A single-sample urine test that flags leaking albumin
Understand your full resultWhat a low Urine albumin-creatinine ratio (UACR) can mean
- Normal (<30 mg/g) — the expected, reassuring result; the kidney filters are holding albumin back.
- A falling ratio on treatment — can show that blood-pressure or diabetes control (or medicines that protect the kidney) are working.
When to discuss with a doctor
A raised urine albumin-creatinine ratio is one of the most useful early warnings in medicine, because it can flag kidney damage before symptoms and before eGFR falls, and it also marks higher cardiovascular risk. In people with diabetes or high blood pressure it is checked routinely, and a persistently raised value usually prompts kidney-protective steps such as tighter blood-pressure and glucose control and specific medicines. Because a single raised result can come from a passing cause like infection, fever, exercise or menstrual blood, it is normally confirmed on one or two repeat samples before conclusions are drawn. A very high ratio, or a rising trend, warrants closer assessment. Mediora.AI shows UACR alongside creatinine, eGFR and urine protein so the early-kidney-damage pattern is visible over time; interpreting it and deciding on treatment belongs with your doctor.
