Urine Protein — What It Means in Your Urine Test
New to reading lab reports? Start with our guide to reading a blood test report
This checks whether protein is leaking into your urine, which can be a sign your kidneys need a look.
In short, Urine Protein flags whether traces of protein are slipping through where they should stay put. A small amount can matter, so a positive result is usually a cue to talk it over with your care team.
Also known as: Proteinuria (dipstick), Urine protein dipstick, Albuminuria (qualitative), Protein (urine)
This isn't a case where higher or lower is better. Your body keeps it in a narrow band, and both directions can matter.

What is Urine Protein?
A chemically treated test strip reacts with albumin and other proteins in the sample, giving a colour that estimates the amount present. Healthy kidney filters normally hold protein back in the blood.
Why is Urine Protein tested?
It is checked to look for protein escaping into the urine. That can be an early sign that your kidney filter is under strain.
What is a normal Urine Protein range?
- India
- No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
- Global
- Negative
Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

A negative result is the usual normal finding. It suggests protein is not leaking into your urine in any meaningful amount.
