Analysis of the results of the SEIMC External Quality Control Programme. Year 2018.

This article provides an analysis of the results obtained in 2018 by the participants inscribed in the External Quality Control Programme of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), which includes controls for bacteriology, serology, mycology, parasitology, mycobacteria, virology, molecular microbiology, and genotypic bacterial resistance. The results obtained in 2018 confirm the excellent skill and good technical standards found in the vast majority of Spanish clinical microbiology laboratories, as shown in previous editions. However, the programme again shows that erroneous results can be obtained in any laboratory and even in clinically relevant determinations. Once again, the results of this programme highlight the need to implement both internal and external controls, as in the SEIMC programme.
