Labs differ a lot here. ARUP prints 3.2 µg/g creatinine or lower on its Cadmium, Urine test and 3.0 or lower on its OSHA exposure panel, Mayo's workplace-exposure version lists a Biological Exposure Index of under 5.0, and OSHA's workplace standard uses 3 µg/g as its initial level. The tighter Mayo limit is used here because it is closer to what US survey data show for the general public: in NHANES 2017-2018, the 90th and 95th percentiles for US adults were about 0.65 and 0.92 µg/g creatinine. Other labs can use different limits, and the range on your own report is the one that applies to your result.","sources":[{"title":"Cadmium/Creatinine Ratio, Random, Urine (Mayo test CDUCR)","url":"https://www.testcatalog.org/show/CDUCR","publisher":"Mayo Clinic Laboratories (catalog mirrored at testcatalog.org)"},{"title":"Cadmium Occupational Exposure, Random, Urine (Mayo test CDUOE)","url":"https://www.testcatalog.org/show/CDUOE","publisher":"Mayo Clinic Laboratories (catalog mirrored at testcatalog.org)"},{"title":"Cadmium, Urine (ARUP test code 0025040)","url":"https://ltd.aruplab.com/Tests/Pub/0025040","publisher":"ARUP Laboratories"},{"title":"Cadmium Exposure Panel - OSHA (ARUP test code 0025013)","url":"https://ltd.aruplab.com/Tests/Pub/0025013","publisher":"ARUP Laboratories"},{"title":"Toxicological Profile for Cadmium (Draft for Public Comment), Chapter 5: Potential for Human Exposure","url":"https://www.atsdr.cdc.gov/toxprofiles/tp5-c5.pdf","publisher":"ATSDR (Agency for Toxic Substances and Disease Registry)","year":2025},{"title":"29 CFR 1910.1027, Cadmium (medical surveillance: biological monitoring levels)","url":"https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.1027","publisher":"U.S. Occupational Safety and Health Administration"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
