Abstract

Se describe un sistema para probar analitos en una muestra de fluido biologico que incluye una tira de prueba que define la cavidad para recibir la muestra. Al menos dos conjuntos de electrodos estan adyacentes a la cavidad de muestra, incluyendo uno para medir una propiedad de la muestra, y otro para medir una o mas de otras propiedades de la muestra, tal como la temperatura y/o la presencia o magnitud de variables de confusion. Las mediciones se combinan para proporcionar el resultado deseado. Al menos un conjunto de electrodos de trabajo y contadores cada uno tiene una pluralidad de piezas separadoras "alargadas" interdigitalizadas con aquellas del otro electrodo en el conjunto. Los huecos entre las piezas separadoras pueden ser totalmente pequenas, de manera que los dos conjuntos de electrodos juntos pueden operar en una medicion pequena de la muestra. Pueden incluirse electrodos adicionales que miden la presencia o suficiencia de la muestra, y trazos adicionales en la tira que pueden actuar como identificadores de configuracion.
