Controle de qualidade no laboratório clínico: hora de mudar?

Abstract

Quality control in clinical analyzes is a crucial point to ensure that the reports and results issued represent the patients' clinical condition. It involves a series of requirements and is based mainly on carrying out daily control tests. The high costs of quality control in clinical laboratories associated with the probability of releasing results with biases lead to constant concern. The deviations observed in the control promote a cascade effect on the laboratory routine, introducing rework and an increase in the consumption of the chemicals used. An additional point to note is the use of commercial substances to carry out the control where matrix effects and the risk of non-commutability may occur, which introduces biases that are not always measurable. A methodology for quality control based on the patient himself and performed in real time is then presented: the Quality Control in Real Time Based on the Patient (CQTRBP), which proposes the use of existing data of the patients themselves to minimize biases associated with the effect matrix and non-commutability, anticipate deviations by promoting quick corrective actions and minimizing rework, in addition to promoting an estimated cost reduction of up to 85% in the inputs for quality control.
