Urine Protein (Dipstick) Normal Ranges
Urine dipstick protein detects protein (primarily albumin) in the urine.
| Reference Range | Unit | Notes |
|---|---|---|
| Negative / Non-reactive | qualitative | Negative to trace (<150 mg/day total protein) |
Also reported in: mg/dL.
Why Doctors Order the Urine Protein (Dipstick) Test
Persistent proteinuria (positive on at least 2 of 3 tests over 3 months) is a defining criterion for Chronic Kidney Disease (CKD). The dipstick primarily detects albumin — it is less sensitive to non-albumin proteins (Bence Jones proteins from myeloma, tubular proteins).
How to Enter Your Urine Protein Result
Urine Protein (Dipstick) is usually reported as a qualitative result — for example negative or positive — so enter it exactly as it is printed on your lab report. Some laboratories also report a numeric value (mg/dL); if yours does, choose the matching unit.
What a Negative or Positive Urine Protein Result Can Mean
Negative (non-reactive) result
- Dipstick protein is negative in normal kidney function
- Dipstick misses small proteins — Bence Jones protein and tubular proteins require specific urine protein electrophoresis
Positive (reactive) result
- Diabetic nephropathy (most common cause of CKD globally)
- Hypertensive nephrosclerosis
- Glomerulonephritis (IgA nephropathy, lupus nephritis, FSGS, membranous nephropathy)
- Nephrotic syndrome (massive proteinuria >3.5 g/day)
- Orthostatic proteinuria (benign — protein appears when standing, clears when lying down)
These are common associations, not a diagnosis. A single result is read alongside your symptoms, history and other tests — discuss it with your doctor.
What Can Change Your Urine Protein Result
Before you read too much into a result, consider whether any of these applied:
- Concentrated urine (high specific gravity) can cause false-positive trace proteinuria — dilute urine gives false-negative
- Highly alkaline urine (pH >8.5) causes false-positive dipstick protein
- Pyuria (pus in urine) can produce false-positive protein
- Quaternary ammonium compounds (some antiseptics) contaminate samples and cause false-positive
Preparing for the test: A fresh midstream urine sample is needed. Avoid testing during or immediately after vigorous exercise (can cause transient proteinuria).
Symptoms That Often Prompt Urine Protein Testing
- Heavy proteinuria (nephrotic range): foamy or bubbly urine
- Edema — puffiness around eyes, swelling of legs and ankles
- Weight gain from fluid retention
- Fatigue from hypoalbuminemia
- Hypertension (common with kidney disease)
