The European Biological Variation Study (EuBIVAS): delivery of updated biological variation estimates, a project by the Working Group on Biological Variation in the European Federation of Clinical Chemistry and Laboratory Medicine

We were really honored by the recent editorial written by Prof. Fraser (1) about biological variation (BV) as a comment on our paper, published in Clinical Chemistry, reporting new BV estimates for nine enzymes (2) based on samples from the European Biological Variation Study (EuBIVAS) (3).
