- Avaliação Externa da Qualidade no âmbito da Hematologia: Experiência PNAEQPublication . Faria, Ana Paula; Correia, Helena; Cardoso, Ana; Brito, Cristina; Barreira, Rui; Reis, Ana; Miranda, Ana; Miranda, ArmandinaIntrodução: O Programa Nacional de Avaliação Externa da Qualidade (PNAEQ), tem como objetivo a promoção de programas de avaliação externa da qualidade, assim como a monitorização do desempenho dos participantes, com vista à melhoria contínua, nomeadamente nos programas de Contagens Celulares (Glóbulos Vermelhos(GV), Glóbulos Brancos (GB), Plaquetas (PLT), Hemoglobina (Hb), Hematócrito (Ht)); Reticulócitos; Hemoglobinopatias e de Morfologia de Sangue Periférico (MSP). Objetivo: A avaliação da performance dos laboratórios participantes, no período de 2011 a 2013, nos programas de Hematologia (Contagem celular, Reticulócitos, Hemoglobinopatias e Morfologia de sangue periférico- MSP) que o PNAEQ disponibiliza, em colaboração com o Grupo de trabalho de Hematologia.

- Delta Beta (δβ) thalassemia: Learning from External Quality AssessmentPublication . Miranda, Armandina; Correia, Helena; Reis, Ana; Miranda, Ana; Silva, Susana Pereira; Seuanes, Filomena; Meireles, Flora; Azevedo, Ana Paula; Faria, Ana PaulaIntroduction: External Quality Assessment Programs (EQA) evaluate retrospectively the laboratory results, assessing their performance and competence. They play a key role in the continuous training process of the professionals, contributing not only for precise and accurate results, but also to a correct interpretation. δβ thalassemia results from a deletion in genes delta and beta of chromosome 11. Although its definitive identification demands genetic analysis, the hematologic evaluation allows the presumptive identification. The hematologic phenotype of heterozygotes for δβ-thalassemia is identic to β-thalassemia carrier, with microcytosis and hypochromia where the percentage of HbA2 is not increased and Hb F is usually high, varying from 5 to 20%. In 2018, the National External Quality Assessment Program (PNAEQ), sent a sample that simulated a carrier of delta beta (δβ) thalassemia, in order to evaluate the performance of the participants registered in the Hemoglobinopathies Program. Objective: Evaluate the performance of PNAEQ’s participants in the quantification of HbA2 and HbF, and interpretation of results of a sample that simulated an δβ-thalassemia carrier.

- Overview of PNAEQ clinical participants during COVID-19 pandemicPublication . Faria, Ana Paula; Correia, Helena; Ventura, Catarina; Cardoso, Ana; Pereira, Edna; Aldeia, Claudia; Júlio, Claudia; Miranda, Armandina; Silva, Cândido; Barreira, Rui; Miranda, Ana; Reis, Ana; Silva, SusanaExternal Quality Assessment Schemes are a crucial tool to identify and evaluate laboratory performance. COVID 19 pandemic poses a challenge for laboratories, since they own a critical role in the diagnosis, prognosis and therapeutic monitoring The laboratory practice in stressful conditions may increase errors due to several factors. The main objective of this study was to evaluate and compare the performance of clinical participants in Portuguese External Quality Assessment Programme (PNAEQ) during the pandemic period (2020) and previous schemes (2019 or 2018) for different parameters of Haematology Chemistry Endocrinology Immunology and Microbiology
