Updated for 2010! Desirable Specifications for imprecision, inaccuracy, and total allowable error, calculated from data on within-subject and between-subject biologic variation. This database is updated and compiled by Dr. Carmen Ricos and colleagues. We are honored to be able to host this database.
Desirable Specifications for Total Error, Imprecision, and Bias, derived from intra- and inter-individual biologic variation
This most recent and extensive listing of biologic goals has been provided by Ricos C, Alvarez V, Cava F, Garcia-Lario JV, Hernandez A, Jimenez CV, Minchinela J, Perich C, Simon M. "Current databases on biologic variation: pros, cons and progress." Scand J Clin Lab Invest 1999;59:491-500. This database was most recently updated in 2010: see what was updated here.
Annex I, Part I: Within-subject and between-subject CV values of analytes and Desirable Analytical Quality Specifications for imprecision, bias and total error
11-Desoxycortisol through a-Fetoprotein Albumin through CA 549 antigen Calcium through Cystein Dehydroepiandrosterone sulfate through Homocysteine Immunoglobulin A through Lycopenene Magnesium through Oxalate, output pCO2 through Rheumatoid factor SCC antigen through Zinc

Note on abbreviations: CVw = within-subject biologic variation CVg = between-subject biologic variation I = desirable specification for imprecision B = desirable specification for inaccuracy TE = desirable specification for allowable total error
