Method and apparatus for enhancing accuracy of an analyte detection system
A method of determining an analyte concentration in a patient. The method comprises estimating an analyte concentration for display on a point-of-care monitor, where the estimating includes obtaining two or more measurements of the analyte concentration. Also disclosed is a device for determining an analyte concentration. The device comprises a sensor configured to measure a bodily fluid of a patient and provide information for display on a point-of-care monitor. The information relates to a measurement of an analyte in a sample. The device further comprises a processor and stored program instructions executable by the processor such that the system is operable to estimate an analyte concentration using two or more measurements of the analyte concentration.
