Resumo
Estudamos o mecanismo da reação de Jaffé para a determinação da creatinina humana, utilizando os métodos cinético e ponto-final. Foi analisada a magnitude de interferência nas constantes físicas (tempo e temperatura de incubação) e no equilíbrio da reação, obtendo-se valores subestimados a 25°C nos 2 métodos estudados. Os resultados a 30°C são coerentes com os valores de referência descritos na literatura. A hiperglicemia interfere mais significantemente na reação de ponto-final, elevando os resultados de creatinina a partir de 290 mg%. O método cinético mostrou-se bastante eficaz na dosagem da creatinina sérica discriminando valores sem interferência de substâncias redutoras e com reprodutibilidade compatível às melhores técnicas laboratoriais.
