Biological variation (BV) data has many appliances in the daily laboratory life, being used both when evaluating the diagnosis and monitoring of disease and for setting analytical performance specifications. Thus, the quality of our work directly depends on the reliability of the BV estimates used as basis for these processes. Widely varying BV estimates are available for different measurands, and it is likely that this may be caused by differences in study design and statistical handling. Addressing this issue, the EFLM established in 2014 an EFLM Task and Finish Group (TFG) for the Biological Variation Database. The TFG is made up by members from the EFLM Working Group on Biological Variation, the Analytical Quality Commission of the Spanish Society of Clinical Chemistry and experts in the area. The TFG has developed a critical appraisal list for evaluation of studies on BV and this will be used as basis for the setup of a database with measures of BV, the derived performance specifications and the evidence behind it.
