Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Protein in urine: what the values can mean
Proteinuria testing helps athletes distinguish between exercise-induced proteinuria, which is temporary and generally benign, and persistent proteinuria that may indicate kidney stress. High-protein diets and intense training can influence results, making baseline testing valuable.
What It Measures
This test measures the total amount of protein present in your urine. The kidneys contain tiny filters (glomeruli) that normally keep large molecules such as proteins from passing into the urine.
When these filters are affected, proteins such as albumin can leak through, which raises the measured amount. A laboratory can indicate how much protein is in the urine, sometimes expressed in grams of protein per day. A small amount is normal. When more than usual is measured, your healthcare provider can look at whether further investigation is needed.
Why It Matters
Protein in urine can be a useful signal when looking at kidney health. Persistent protein in urine is sometimes associated with raised blood pressure (hypertension) or with other changes, such as blood in the urine. Your GP can help you understand what the result may mean in your situation.
Protein in urine is often viewed alongside other kidney values, such as creatinine, eGFR, albumin and urea. Together these values may help your healthcare provider get a clearer view of your kidney function.
When to Test
Some people choose to test periodically to stay informed about their health, for example when they have diabetes, raised blood pressure or a family history of kidney conditions.
A blood or urine test gives a data point, not a diagnosis. Your GP can help you decide whether testing is useful in your situation and how to interpret the result.

Recommendations
Male
Normal urine protein indicates healthy kidney function. No action needed.
Elevated urine protein (proteinuria) may indicate kidney damage or disease. Consult your healthcare provider for comprehensive kidney evaluation.
Female
Normal urine protein indicates healthy kidney function. No action needed.
Elevated urine protein (proteinuria) may indicate kidney damage or disease. Consult your healthcare provider for comprehensive kidney evaluation.
Lifestyle Tips
Control blood pressure and blood sugar levels, as hypertension and diabetes are the most common causes of proteinuria. Reduce sodium intake and follow a balanced diet that is appropriate for kidney health.
Avoid excessive protein consumption, which can place additional strain on the kidneys. Stay hydrated, exercise regularly, and avoid smoking. Discuss all medications and supplements with your healthcare provider, as some can affect kidney function.
