RESUMO

Se revisan los antecedentes históricos del conteo de reticulocitos como determinación indispensable en el laboratorio de hematología para la evaluación de la actividad eritropoyética durante la clasificación, diagnóstico y monitoreo de la respuesta terapéutica en distintos trastornos y situaciones clínicas, principalmente en casos de anemias. Se describe el tránsito del tradicional método de conteo de reticulocitos manual al método automatizado y la integración de los parámetros reticulocitarios al hemograma automatizado actual; además, se analizan las desventajas del método de recuento manual y las ventajas del método automatizado, así como los principios de detección en que se basa el conteo electrónico de reticulocitos. Con relación a los parámetros reticulocitarios, se describe su medición, cálculo y unidades de medida; también se resalta la importancia de la fracción de reticulocitos inmaduros y del contenido de hemoglobina reticulocitaria como variables de mayor uso clínico e investigativo en la evaluación de la respuesta medular ante diversos trastornos clínicos y protocolos terapéuticos. Por último, se alude a la necesidad del conocimiento y empleo de las variables reticulocitarias en la práctica clínica de rutina por parte de los clínicos y especialistas en hematología.


The historical background of reticulocyte count is reviewed as an essential determination in the laboratory of hematology for the evaluation of erythropoietic activity during classification, diagnosis and monitoring of therapeutic response of different conditions and clinical situations are also reviewed, especially in anemia The transition from traditional manual reticulocyte counting method to automated method and integration of the reticulocyte parameters to current automated complete blood count are described. The disadvantages of manual method and the advantages of automated methods are cited, as well as detection principles in which electronic reticulocyte count is based. Regarding reticulocyte parameters, measurement, calculation and units are described. The importance of immature reticulocyte fraction and reticulocyte hemoglobin content as variables most clinical and research use in evaluating bone marrow response to various clinical disorders and therapeutic protocols are highlighted. Finally, the need for knowledge and use of reticulocyte variables in routine clinical practice by clinicians and hematologist is referred.

RESUMO

The reticulocyte count reflects the erythropoietic activity of bone marrow and is thus useful in both diagnosing anemias and monitoring bone marrow response to therapy. Automated flow-cytometric analysis has led to a significant advance in reticulocyte counting, by simultaneously providing additional parameters and indices such as the reticulocyte immature reticulocyte fraction (IRF), the reticulocyte volume, and the hemoglobin content and concentration. IRF has been proposed as an early marker of engraftment. Reticulocyte hemoglobin content is useful in assessing the functional iron available for erythropoiesis, and reticulocyte volume is a useful indicator when monitoring the therapeutic response of anemias.
