Abstract

Se da a conocer un método, un sistema y medios legibles por computadora para estimar una cantidad de un analito en la sangre de un sujeto. En un ejemplo, un método incluye obtener una corriente de ruido filtrado al filtrar el ruido de una corriente recibida de un sensor de analito colocado intersticialmente en el tejido del sujeto, estimar uno o más parámetros de calibración de analito en sangre con base en la corriente de ruido filtrado, obtener un segundo conjunto de uno o más parámetros de calibración de analito intersticial con base por lo menos en parte en uno o más de los parámetros de calibración de analito en sangre y estimar la cantidad del analito en la sangre del sujeto con base en la corriente de ruido filtrado y uno o más de los parámetros de calibración de analito intersticial. De esta manera, un sensor de analito que se coloca intersticialmente puede ser calibrado fácilmente para reportar valores exactos de analito en sangre.
