COMPARING THE ACCURACY OF THE POINT-OF-CARE BLOOD COUNT WITH A CONVENTIONAL LABORATORY ANALYSIS METHOD

Complete blood count is one of the most commonly requested tests and is highly relevant for diagnosis, treatment and clinical monitoring.However, the conventional analysis method requires collection by venipuncture and requires more time, as well as specialized equipment and personnel.Point-of-care (POC) technology has made great advances and revolutionized diagnostic methods, presenting diverse applications and the possibility of faster, more accessible and minimally invasive tests.The objective of this study is to compare the accuracy of POC technology for blood count analysis, using only a drop of blood, with the conventional analysis method.Adult patients (over 18 years old) from the Canoas Emergency Hospital who underwent complete blood count were selected.The POC device for this study was the RevDx system developed by EfA Technologies and the results obtained were compared with those generated by the automated hematology analyzer model Pentra XL 80.To assess the agreement and accuracy between the two methods, Pearson's correlation coefficient was used.A high level of agreement was observed between the two methods, especially for parameters such as WBC, HGB and NEU_%, indicating that RevDx performs well compared to the conventional method for these parameters.The parameters HGB and NEU_abs presented a Bias close to zero, indicating that there is no significant systematic difference between the two methods.The results of this study demonstrated high agreement between CBC measurements obtained by the traditional method (Pentra XL 80) and by the RevDx device through strong correlations that indicate a significant accuracy of the POC technology.This study validates the effectiveness of RevDx and highlights the importance of implementing innovative technologies at the point of care to optimize healthcare.
