Malaria, one of the main worldwide health diseases, is caused by Plasmodium species being of utmost importance the correct identification of each Plasmodium spp. Since 1995, the National Program for External Quality Assessment (PNAEQ) has implemented a Parasitic Morphology program which aims to evaluate the performance of participant laboratories in the identification of parasitic structures. To continually improve their performance, PNAEQ, in collaboration with a work group, provide updated scientific reports, courses and, when needed, implement corrective actions. The aim of this study is to evaluate performance of the participants in the Parasitic Morphology program, in the identification of Plasmodium falciparum, Plasmodium malariae and Plasmodium ovale, from 2011 to 2018.
