Abstract
Un método y un aparato se revela para medir la concentracion de un analito presente en un fluido biologico. El método incluye los pasos de aplicar radiacion NIR a muestras de calibracion para producir datos de calibracion, analizar los datos de calibracion para identificar y eliminar resultados aislados, construir un modelo de calibracion, colectar y analizar muestras desconocidas para identificar y eliminar resultados aislados, y predecir la concentracion del analito de resultados no aislados con el modelo de calibracion. El análisis de los datos de calibracion incluye pretratamiento de datos, descomposicion de datos para eliminar datos redundantes, identificacion y eliminacion de resultados aislados usando intervalos generalizados. El aparato (100) incluye una bomba (102) que circula una muestra a través de un tubo (104) para llenar un flujo de células (106). La luz de una fuente NIR (114) se sincroniza con un detector (110), facilita las mediciones de luz y obscuridad, y pasa a través de un monocrometro (120) y el flujo de células (106) y recto al detector (110), donde la radiacion transmitida a través de la muestra se mide.
