Abstract

UN PROCEDIMIENTO DE ENSAYO QUE ES ESPECIALMENTE UTILIZABLE PARA DETECTAR Y/O DETERMINAR LA PRESENCIA DE NIVELES LIMITE DELIGANDOS ANALITO EN FLUIDOS BIOLOGICOS. EN UN ASPECTO PARTICULARIZADO Y ESPECIALIZADO LA INVENCION SE DIRIGE A PROCEDIMIENTOS PARA DETECTAR Y/O DETERMINAR NIVELES LIMITE DE METABOLITOS DE HORMONAS, TALES COMO PREGNANODIOL-3-GLUCURONIDA (P3G) Y ESTRONA-3-GLUCURONIDA (E13G) EN ORINA HUMANA. EL ENSAYO CONSISTE EN PONER EN CONTACTO UNA MUESTRA QUE CONTIENE EL ANALITO CON UNA CANTIDAD CONOCIDA DE UN ANTICUERPO SUYO Y CON UNA CANTIDAD CALIBRADA DEL ANALITO MISMO QUE ESTA CONJUGADO A DICHO SOPORTE SOLIDO. CUANDO EL NIVEL DEL ANALITO EN LA MUESTRA EXCEDE UN NIVEL LIMITE, TAL COMO 5 (MU)G/ML PARA P3G, EL ANTICUERPO SERA INSUFICIENTE PARA BLOQUEAR TODO EL ANALITO CORRESPONDIENTE EN EL SOPORTE SOLIDO. ASI, POR ADICION DE ANTICUERPO MARCADO AL SISTEMA DE ENSAYO, SE LLEGA A UNIR AL SOPORTE UN PRODUCTO DE INMUNORREACCION DETECTABLE PARA INDICAR QUE LA CANTIDAD DE ANALITO EN LA MUESTRA EXCEDE EL NIVEL LIMITE. POR OTRA PARTE, SI EL NIVEL DEL ANALITO EN LA MUESTRA ES INFERIOR A LA CANTIDAD LIMITE, EL ANTICUERPO LIBRE SERA SUFICIENTE PARA BLOQUEAR TODO EL ANALITO CORRESPONDIENTE EN EL SOPORTE SOLIDO, EVITANDO QUE EL ANTICUERPO MARCADO FORME UN PRODUCTO DE INMUNORREACCION DETECTABLE SOBRE EL SOPORTE, Y ASI NO APARECE SEÑAL.
