The KDIGO kidney guideline treats under 150 mg/24 h as normal to mildly increased. Mayo prints a higher limit, under 229 mg/24 h, for adults and has not set one for people under 18. ARUP, Quest and MedlinePlus give no age split, so this range is applied to adults only. A lower limit is not clinically meaningful, so this range starts at 0. Hard exercise can push healthy people to about 300 mg/24 h. Your report's own range comes first.","sources":[{"title":"Protein, Total, Urine (test 0020479)","url":"https://ltd.aruplab.com/Tests/Pub/0020479","publisher":"ARUP Laboratories"},{"title":"Urine protein dipstick test (includes the 24-hour urine protein range)","url":"https://medlineplus.gov/ency/article/003580.htm","publisher":"MedlinePlus Medical Encyclopedia (NIH National Library of Medicine)"},{"title":"KDIGO 2012 Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease, Chapter 1: Definition and classification of CKD","url":"https://doi.org/10.1038/kisup.2012.64","publisher":"Kidney International Supplements","year":2013},{"title":"Protein, Total, 24-Hour Urine without Creatinine (test code 11320)","url":"https://testdirectory.questdiagnostics.com/test/test-detail/11320/protein-total-24-hour-urine-without-creatinine?cc=MASTER","publisher":"Quest Diagnostics"},{"title":"PTU - Protein, Total, 24 Hour, Urine","url":"https://www.mayocliniclabs.com/test-catalog/overview/614001/protein-total-24-hour-urine","publisher":"Mayo Clinic Laboratories"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
