High Urine protein (proteinuria): what it means
A Urine protein (proteinuria) result above the normal range is considered high. Here is what a raised Urine protein (proteinuria) can point to, and when it is worth discussing with a doctor.
Reference range: roughly <150 mg/day (or <150 mg/g on a protein-creatinine ratio); more protein in the urine signals kidney damage — the amount helps grade its severity
Understand your full resultWhat a high Urine protein (proteinuria) can mean
- Kidney (glomerular) damage — the commonest meaning; from diabetes, high blood pressure or glomerular disease.
- Nephrotic-range proteinuria (very heavy loss) — points to specific glomerular diseases and causes swelling and a low blood albumin.
- Tubular kidney damage — a different pattern of protein loss.
- Transient proteinuria — fever, vigorous exercise, or urinary infection; usually resolves and needs repeating.
- Overflow proteinuria — occasionally from excess abnormal proteins in the blood, as in multiple myeloma.
When to discuss with a doctor
Persistent protein in the urine is an important finding because it both signals kidney damage and, independently, raises the risk of that kidney disease progressing — so reducing it is a central aim of kidney care. The amount guides how concerning it is: heavy, nephrotic-range loss needs prompt specialist assessment to find the specific cause, while milder proteinuria is monitored and treated with blood-pressure control and kidney-protective medicines. Because a one-off positive can come from fever, exercise or infection, proteinuria is confirmed on repeat testing before it is acted on. It is always read together with eGFR to stage kidney disease. Mediora.AI shows urine protein alongside eGFR, the albumin-creatinine ratio and blood albumin so the kidney picture is seen as a whole and trends are visible; interpreting the pattern and directing treatment belongs with your doctor.
