This limit matches the 5 µg/L whole-blood level in OSHA's workplace cadmium standard, so it works as a toxicity and workplace screen. It is not the middle 95% of healthy people. In a US government survey (NHANES 2017-2018), half of adults were at or below about 0.27 µg/L and 95% were at or below about 1.4 µg/L. Smokers usually run higher. Other labs can use different limits, and the range on your own report is the one that applies to your result.","sources":[{"title":"Cadmium, Whole Blood (ARUP test code 0099675)","url":"https://ltd.aruplab.com/Tests/Pub/0099675","publisher":"ARUP Laboratories"},{"title":"Heavy Metals Screen with Demographics, Blood (Mayo test HMDB, cadmium result CDB)","url":"https://www.testcatalog.org/show/HMDB","publisher":"Mayo Clinic Laboratories (catalog mirrored at testcatalog.org)"},{"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"},{"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}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
