Abstract

Die Erfindung betrifft ein Verfahren und einen Blutmessstreifen (100) zur Messung der Kaliumkonzentration in einer Blutprobe unter Verwendung eines Auslesegeräts (200), wobei der Blutmessstreifen (100) einen Eingangsbereich (1) zur Aufnahme der Blutprobe aufweist und einen mit dem Eingangsbereich (1) verbundenen Messbereich (3), wobei in dem Messbereich (3) ein lumineszenter Indikatorfarbstoff angeordnet ist, dessen Intensität der Lumineszenz von der Kaliumkonzentration der Blutprobe abhängt, dadurch gekennzeichnet, dass in dem Messbereich (3) ein lumineszenter Referenzfarbstoff angeordnet ist, dessen Intensität und Abklingzeit der Lumineszenz nicht von der Kaliumkonzentration der Blutprobe abhängtThe invention relates to a method and a blood test strip (100) for measuring the potassium concentration in a blood sample using a reader (200), wherein the blood test strip (100) has an input region (1) for receiving the blood sample and a measuring region (3) connected to the input region (1), wherein a luminescent indicator dye is arranged in the measuring region (3), the intensity of the luminescence of which depends on the potassium concentration of the blood sample, characterized in that a luminescent reference dye is arranged in the measuring region (3), the intensity and decay time of the luminescence of which does not depend on the potassium concentration of the blood sample
