Abstract
LOS ERITROCITOS EXISTEN IN VIVO EN UN GRADIENTE CONTINUO DE SUBCONJUNTOS CELULARES DE DENSIDAD SIENDO LAS CELULAS MAS JOVENES LAS MAS LIGERAS. UNA MUESTRA DE SANGRE SE CENTRIFUGA EN UN TUBO TRANSPARENTE QUE CONTIENE GOTAS DE PLASTICO QUE SE SELECCIONAN PARA INCLUIR GRUPOS DE GOTAS EN LOS QUE CADA GRUPO TENGA UNA GRAVEDAD ESPECIFICA DIFERENTE, Y QUE SE DISTRIBUYEN DENTRO DE LA BANDA DE LAS DENSIDADES DE LOS GLOBULOS ROJOS. LAS GOTITAS FORMAN BANDAS SEPARADAS Y ESTRECHAS EN LAS CAPA DE ERITROCITOS, DICHAS BANDAS FORMAN ENLACES ENTRE LAS DIFERENTES CAPAS DE SUBCONJUNTOS DE CELULAS. LA MEDIDA DE LAS LONGITUDES DE LAS DIFERENTES CAPAS DE SUBCONJUNTO DE CELULAS SIRVE PARA CUANTIFICAR LOS SUBCONJUNTOS DE GLOBULOS ROJOS EN LA SANGRE DEL PACIENTE.
