Abstract

LAS CAPAS DE CELULAS SON RECOGIDAS DE UN MATERIAL MULTICELULA CENTRIFUGADO EN UN TUBO DE EVACUACION O TUBO DE PLASTICO QUE CONTIENE UNA NATA (6). CUANDO SE ANALIZAN MATERIALES POSIBLEMENTE CONTAMINADOS, COMO SANGRE, LA UTILIZACION DE UN TUBO DE EVACUACION PERMITEN HACER LAS MEDICIONES SIN QUE EL ANALISTA ESTE EXPUESTO A LA SANGRE. LOS TUBOS SON LO SUFICIENTEMENTE GRANDES COMO PARA CONTENER 1 ML DE SANGRE, Y ESTAN RELLENOS CON UN GAS INERTE A BAJA PRESION. LAS NATAS SE FORMAN A TRAVES DE UN ORIFICIO (7) DENTRO DEL CUAL LAS BANDAS DE CELULAS A RECOLECTAR SE SEDIMENTAN DURANTE LA CENTRIFUGACION. LAS BANDAS DE CELULAS (A-E) SON ESTABILIZADAS POR UNA CAPA DE UN MATERIAL FLOTANTE QUE SE SEDIMENTA SOBRE LA CAPA DE PLASMA DURANTE LA CENTRIFUGACION, FORMANDO UNA PELICULA SOBRE EL ANTERIOR. LAS CAPAS DE CELULAS A RECOLECTAR SON ASPIRADAS DEL ORIFICIO DE LA NATA POR MEDIO DE UNA AGUJA HIPODERMICA (131) O CANULA INSERTADA EN EL TUBO.
