Abstract

Den foreliggende oppfinnelsen angår elektrokjemiske sensorstrips og fremgangsmåter for å bestemme konsentrasjonen av en analytt i en prøve eller å forbedre ytelsen av en konsentrasjonsbestemmelse. De elektrokjemiske sensorstripsene kan inkludere på det meste 8 µg/mm2 av en akselerator. Stripsene, stripsreagenslaget eller fremgangsmåtene kan tilveiebringe for bestemmelsen av en konsentrasjonsverdi som har i det minste én av en stabilitetsskjevhet på mindre enn ± 10 % etter oppbevaring ved 50 °C i 4 uker sammenlignet med en sammenligningsstrips oppbevart ved 20 °C i 4 uker, en hematokrittskjevhet på mindre enn ± 10 % for helt blod prøver inkluderende fra 20 til 60% hematokritt, og et skjæringspunkt til stigningsvinkelforhold på i det meste 20 mg/dl. En fremgangsmåte for å øke ytelsen av en kvantitativ analyttbestemmelse er også tilveiebrakt.
