Remote Audit for Quality Control Evaluation in Four Clinical Laboratories focus in hematologic parameters - Portugal and Brazil, 2018

The external audit is an evaluation feature of the clinical laboratories Quality Management System (QMS), which aims to determine if the quality requirements, according to an implemented normative reference, comply with good laboratory practices. Analytical Quality Control (AQC) in clinical laboratory is an analytical method error detection system that includes Internal Quality Control (IQC) and External Quality Control (EQC), allowing the transmission of precise and accurate results. Count Blood Cells (CBC) is one of the most frequently requested laboratory tests, and is the basis of numerous medical interventions, and therefore the transmission of reliable and appropriate analytical results is very important. The results presented is part of the thesis for conclusion the clinical analysis master's. The assessment simulates a remote quality audit according to ISO NP EN ISO 15189:2014. The main objective is to validate online questionnaire and spreadsheets, used to collect data of QMS and to evaluate IQC and EQC results in the area of hematology, as quality indicators from four clinical laboratories.N/
