Protein, Urine (Dipstick, Qualitative)

Sample type: Urine

Other names: Urine Protein (Qualitative), Protein—Urinalysis (Qual), Protein Dipstick

Updated September 2, 2026

Negative/Not Detected

Your urine dipstick showed no detectable protein, which is the expected result. Keep up kidney-healthy habits: stay well hydrated, maintain a balanced diet, and monitor blood pressure and blood sugar if applicable. Routine rechecks follow your clinician’s schedule or annual wellness testing.

Trace

Your result shows Trace protein in the urine — a very small amount that is often temporary. This can be caused by recent strenuous exercise, fever or illness, dehydration, or a mild urinary tract infection (UTI). A good next step is to repeat the test with a first-morning urine sample after proper hydration. If trace protein remains present, your clinician may order a urine albumin-to-creatinine ratio (uACR) or protein-to-creatinine ratio (UPCR) to measure it more accurately and check kidney function with blood tests such as creatinine and eGFR.

1+

Your test shows 1+ protein, indicating a modest increase above normal. This should be confirmed with a first-morning urine and a uACR/UPCR to measure the exact amount. Review recent exercise, illnesses, and medications, and ensure good hydration. If you have diabetes, high blood pressure, or are pregnant, contact your clinician to plan follow-up and monitoring.

2+

Your result is 2+ protein, which raises concern for meaningful protein loss in urine. Arrange prompt follow-up for quantitative testing (uACR/UPCR) and blood work (creatinine/eGFR). Managing blood pressure, blood sugar, and any infection is important. Your clinician may increase monitoring frequency and consider a nephrology referral depending on the quantified result and your risk factors.

3+

You have 3+ protein, a high grade that warrants timely evaluation. Expect confirmatory first-morning testing, uACR/UPCR, kidney function labs, and assessment for contributing conditions (e.g., diabetes, hypertension, autoimmune disease, UTI). Treatment focuses on the cause and kidney protection strategies; a nephrology referral is commonly considered.

4+

Your dipstick is 4+ protein, indicating a very high level of urinary protein and a medical priority. Contact your clinician for urgent confirmatory testing (uACR/UPCR), comprehensive labs, and management. If you also have swelling, sudden weight gain, foamy urine, severe high blood pressure, or are pregnant, seek same-day medical advice. A nephrology referral is likely.

Urine Protein Dipstick Test (Proteinuria Screening)

This simple urine dipstick test checks whether protein is present in your urine. Normally, your kidneys filter waste but keep important proteins in the bloodstream. If the kidney filters (glomeruli) are stressed or damaged, protein can leak into the urine.

Results are qualitative, meaning they give a rough estimate rather than an exact measurement. They are reported as Negative, Trace, or graded 1+ to 4+, with higher numbers suggesting more protein loss.

Why protein in urine matters

Finding protein in urine (proteinuria) may be an early sign of kidney disease, especially in people with high blood pressure, diabetes, or abnormal kidney blood tests such as creatinine or eGFR.

Sometimes a positive result is temporary and not related to kidney disease. This can happen after strenuous exercise, fever, dehydration, urinary tract infections (UTIs), or during pregnancy (when extra checks for preeclampsia may be needed).

Understanding your result

  • Negative: No protein detected. This is the normal finding.

  • Trace: A very small amount of protein; often temporary. A repeat test is often recommended.

  • 1+ to 4+: Increasing amounts of protein. The higher the grade, the more concern for possible kidney involvement, and follow-up testing is usually needed.

Next steps and follow-up

If your test shows Trace or higher, your healthcare provider may:

  • Repeat the test, ideally using a first-morning urine sample for accuracy

  • Order a urine albumin-to-creatinine ratio (uACR) or protein-to-creatinine ratio (UPCR) to measure protein more precisely

  • Check related tests such as blood pressure, blood sugar, creatinine, eGFR, or order imaging studies

  • Refer you to a kidney specialist (nephrologist) if protein persists

Lifestyle steps can also help:

  • Stay well hydrated

  • Control blood pressure and blood sugar

  • Treat urinary tract infections promptly

  • Avoid very intense exercise for 24–48 hours before repeat testing

How to prepare for testing

  • Use a clean-catch, first-morning urine sample for the best accuracy

  • Avoid heavy workouts, illness with fever, or dehydration before the test when possible

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
