Labs differ a little: MedlinePlus lists, and OHSU (from age 6) and Parkview print, 32–36; Labcorp prints 31.5–35.7 (the same on its sample reports for women aged 46 and 60 and a 15-year-old boy); ARUP prints 31.9–35.2 for men and 31.2–34.5 for women. Values above the range are uncommon and are often sample effects, though hereditary spherocytosis is a true cause. Check the unit on your report: g/L labs print about 10 times the g/dL number (for example 330 instead of 33). Children's intervals are lower in infancy and are not included here.","sources":[{"title":"RBC indices","url":"https://medlineplus.gov/ency/article/003648.htm","publisher":"MedlinePlus, National Library of Medicine"},{"title":"CBC with Differential: reference ranges (OHSU Lab Services test directory)","url":"https://www.ohsu.edu/lab-services/cbc-differential","publisher":"Oregon Health & Science University Lab Services"},{"title":"Complete Blood Count with Differential (Parkview Laboratory test directory)","url":"https://lab.parkview.com/test-directory/complete-blood-count-with-differential/","publisher":"Parkview Health Laboratory"},{"title":"Sample report, CBC, Platelet, No Differential (test 028142)","url":"https://files.labcorp.com/testmenu-d8/sample_reports/028142.pdf","publisher":"Labcorp","year":2020},{"title":"Sample report, CBC With Differential/Platelet (test 005009)","url":"https://files.labcorp.com/testmenu-d8/sample_reports/005009.pdf","publisher":"Labcorp"},{"title":"CBC with Platelet Count and Automated Differential (ARUP test 0040003), reference intervals effective March 1, 2021","url":"https://ltd.aruplab.com/api/ltd/hotline/0040003/44232","publisher":"ARUP Laboratories","year":2021},{"title":"MCHC: Mean Corpuscular Hemoglobin Concentration (conversion and formula reference)","url":"https://unitslab.com/node/5","publisher":"UnitsLab"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
