Abstract

Se proveé una tira de prueba para aplicar líquido en la misma y para determinar la presencia o cantidad de un analito en tal líquido; específicamente, la tira de prueba consiste de una zona de reaccion, la cual varía en reflectancia como una funcion de la cantidad de analito presente en el líquido aplicado; la tira se inserta en un aparato de lectura optica. Una zona normal está posicionada sobre la tira de forma tal que guíe la zona de reaccion al insertar la tira en el aparato de lectura; el aparato puede ser entonces provisto con mediosopticos para determinar secuencialmente el valor de reflectancia de la zona normal cuando la tira es insertada en su posicion completamente insertada en el aparato y el valor de reflectancia de la zona de reaccion después de que la tira ha sido insertada; el aparato está adicionalmente provisto con medios para calcular la presencia y/o cantidad del analito en cuestion como una funcion de la reflectancia de la zona normal y de la reflectancia de la zona de reaccion.
