Desirable Biological Variation Database specifications PDF Print

Updated for 2012! 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 2012.

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
