Abstract

UN METODO PARA DETERMINAR LA CANTIDAD DE UNA ANALITA EN UN FLUIDO DE MUESTRA UTILIZA UN ELEMENTO DE ENSAYO MULTICAPA QUE INCLUYE POR LO MENOS UNA CAPA REAGENTE Y UNA CAPA DE BARRERA PARA LA LUZ. EL METODO DE ENSAYO COMPRENDE LOS PASOS DE LEER OPTICAMENTE UNA SEÑAL QUE PRODUCE ESPECIE, P. EJ. UNA ETIQUETA FLUORESCENTE; UN PRIMER TIEMPO ANTES DE QUE EL FLUIDO DE MUESTRA SE APLIQUE AL ELEMENTO DE ENSAYO Y UN SEGUNDO TIEMPO, CON LA MISMA LONGITUD DE ONDA Y LA MISMA COLOCACION DENTRO DEL ELEMENTO DE ENSAYO, DESPUES DE QUE EL FLUIDO DE MUESTRA SE HAYA APLICADO AL ELEMENTO DE PRUEBA Y LA ANALITA DE MUESTRA HAYA REACCIONADO CON EL (LOS) REAGENTE(S) DEL ELEMENTO DE ENSAYO. LA RELACION DE LAS DOS SEÑALES SE DETECTA Y COMPARA CON LA DE CANTIDADES CONOCIDAS DE LA ANALITA PARA DETERMINAR LA CANTIDAD DE ANALITA EN EL FLUIDO DE MUESTRA.
