What should you know about urinalysis protein?

Healthy kidneys usually keep most protein in the bloodstream. A dipstick may detect protein after strenuous exercise, fever, dehydration, or an illness, and a single finding does not establish kidney disease. Persistent protein can signal that the kidney filters are allowing more protein through than expected. Clinicians may repeat the urine sample, measure a protein-to-creatinine or albumin-to-creatinine ratio, check blood pressure, and order blood tests for kidney function. Protein may occur with infection or blood in the urine, so the whole pattern matters.

Ask how much protein was detected and whether the sample should be repeated when you are well. Tell the clinician about fever, recent exercise, urinary symptoms, swelling, diabetes, high blood pressure, pregnancy, and medicines. Keep taking prescribed treatment unless told otherwise, and avoid taking anti-inflammatory pain medicines repeatedly without advice if kidney problems are being considered. Keep follow-up appointments so a persistent finding is not overlooked.

Arrange prompt assessment for new swelling around the eyes or ankles, much less urine, blood-coloured urine, breathlessness, severe headache, or a marked change in blood pressure. Fever with side or back pain, vomiting, or painful urination may indicate an infection needing timely care. Seek emergency help for confusion, collapse, severe breathlessness, or rapidly worsening symptoms.

Was the protein trace, mild, or clearly raised? Should I repeat the sample? Do I need kidney blood tests or a urine ratio? Could pregnancy, infection, or my medicines affect this result?
