Why is the Urine Protein test done?
It is part of the routine urine test and screens for kidney disease and pre-eclampsia in pregnancy.
What does a positive Urine Protein result mean?
Protein in the urine (proteinuria) can be temporary or a sign of kidney damage. Persistent protein needs investigation; foamy urine and swelling are warning signs.
Common causes
- Fever, heavy exercise or standing for long periods (temporary)
- Urinary infection
- Diabetes or high blood pressure affecting the kidneys
- Kidney inflammation
- Pre-eclampsia in pregnancy
What can help
- Control blood sugar and blood pressure
- Limit salt
- Avoid painkillers such as ibuprofen
- Avoid protein supplements
When should you see a doctor?
Repeat the test; persistent protein needs a urine albumin-to-creatinine ratio and kidney tests. In pregnancy with high blood pressure, contact your doctor the same day.
