Protein (24hr)

Urine_kidney Unit: mg/24hr Urine test

Quantitative protein measurement over 24 hours

Also known as: 24-Hour Urine Protein,Total Protein 24hr

Reference Ranges

Clinical Reference 0.0 – 150.0 mg/24hr

Optimal Range 0.0 – 80.0 mg/24hr

>150 = proteinuria; >3500 = nephrotic range

Related Conditions

Kidney Disease High

Hypertension High

Food & Lifestyle Recommendations

🍎 Food Limit sodium to under 2,000mg/day — sodium restriction reduces proteinuria Sodium restriction reduces proteinuria by 20-30% independent of BP reduction

🍎 Food Choose plant proteins over animal proteins when possible Plant proteins produce less acid and reduce hyperfiltration compared to animal proteins

Evidence-Backed Supplements

When High

Omega 3 Tier A May Decrease

Moderate evidence; omega-3 reduces proteinuria in CKD populations.

Fish oil (EPA+DHA) 1000–2000 mg EPA+DHA/day With meals

PMID 30019766 PMID 32114706 PMID 30480773
Probiotics Tier A May Decrease

Limited evidence; probiotics may reduce uremic toxins and proteinuria by modifying gut microbiota.

Multi-strain probiotic (Lactobacillus + Bifidobacterium) 5–50 billion CFU/day Morning on empty stomach

PMID 36001877 PMID 25927096 PMID 32128794

Questions to Ask Your Doctor

Is my 24-hour protein level high enough to warrant a kidney biopsy or referral to a nephrologist? >1g/day warrants nephrology referral; >3.5g/day = nephrotic syndrome.
