Abstract

SOPORTE DE MUESTRA PARA DETERMINAR UN ANALITO DE SANGRE PURA. EL SOPORTE CONTIENE UN SISTEMA REACTIVO EN UN CAMPO DE MUESTRA. EL CAMPO DE MUESTRA TIENE UN LATERAL CON LA PRUEBA A DETERMINAR EN DONDE SE REALIZA LA PRUEBA DE SANGRE Y UN LATERAL DE COMPROBACION EN DONDE SE VERIFICA UNA MODIFICACION COMPROBABLE OPTICAMENTE SEGUN LAS REACCIONES DE ANALISIS. SE CONFORMA ASI, YA QUE LOS CORPUSCULOS DE SANGRE ROJA NO PUEDEN PASAR FACILMENTE DEL LATERAL CON LA PRUEBA AL LATERAL DE LA COMPROBACION Y CONTIENE PARTICULAS DE PIGMENTOS PARA EL BLOQUEO OPTICO DEL PIGMENTO SANGUINEO ROJO (HEMOGLOBINA). UNA SEPARACION SEGURA DE LA HEMOGLOBINA SE LOGRA EN UN PROCEDIMIENTO SENCILLO, EN EL CAMPO (5) DE MUESTRA QUE PRESENTA UNA COMBINACION DE CAPAS DE SEPARACION DE PIGMENTO SANGUINEO (HEMOGLOBINA) Y LA CAPA DE COMPROBACION (1) QUE REALIZA EN UNA UNICA CAPA HOMOGENEA Y DELGADA LAS FUNCIONES DE SEPARACION DE CORPUSCULOS DE SANGRE ROJA Y LA COMPROBACION OPTICA. SE FORMAN EN UNA DISPERSION O UNA EMULSION DE UNOS FORMADORES DE PELICULA POLIMERICAS QUE CONTIENEN EN UNA DISTRIBUCION HOMOGENEA, EL PIGMENTO, EL FORMADOR DE LA PELICULA POLIMERO, EL REACTIVO FORMADOS DE COLOR DEL SISTEMA REACTIVO Y UN MEDIO DE ABSORCION.
