Abstract

Tira de electrodo alargada para realizar una medición electroquímica de un analito en sangre íntegra o en una muestra acuosa, comprendiendo electrodos para realizar la medición, en donde dichos electrodos están cubiertos con una capa de malla que se extiende una distancia más allá de los electrodos, a lo largo de la longitud de la tira, dicha malla estando cubierta por una capa impermeable a los líquidos en la que hay una abertura que no cubre los electrodos, caracterizada porque una obstrucción parcial de dicha malla cubre dicha abertura, la cual obstrucción parcial reduce el volumen total de sangre o muestra acuosa necesario para realizar la medición.
