Abstract

tira de teste analítico de base eletroquímica para a determinação de um analito em uma amostra de fluido corporal. a presente invenção refere-se a uma tira de teste analítico de base eletroquímica (10) para determinação de um analito (por exemplo, glicose) em uma amostra de fluido corporal (por exemplo, uma amostra de sangue total) que inclui uma camada de base eletricamente isolante (12) e uma camada condutora dotada de um padrão (14) (por exemplo, uma cama da condutora de ouro dotada de um padrão) disposta sobre a camada eletricamente isolante (12). a camada condutora dotada de um padrão (14) inclui ao menos um eletrodo (14a, 14b, 14c), com o eletrodo (14a, 14b, 14c) tendo áreas eletroquimicamente inertes (26) e área(s) eletroquimicamente ativa(s) (28). além disso, as áreas eletroquimicamente inertes (26) e a(s) área(s) eletroquimicamente ativa(s) (28) são de tamanho predeterminado e de distribuição predeterminada de forma que a resposta eletroquímica do eletrodo (14a, 14b, 14c) durante o uso da tira de teste analítico de base eletroquímica (10) é essencialmente equivalente a uma resposta eletroquímica predeterminada.
