Tietz 7e · Appendix A · Tables A.1–A.5 ·

Reference intervals are method- and population-dependent. Tietz states these values are for general information only; every laboratory establishes or verifies its own intervals (CLSI EP28-A3c/C28-A3) before clinical use. Biological-variation specifications come from the Ricos et al. database (2014 update) hosted by Westgard QC, and are shown only for analytes present in it. Values here are parsed from the printed appendix tables — spot-check against the source before quoting. Not a diagnostic device.
