Abstract
Methods and devices to detect analyte in body fluid are provided. Embodiments include receiving one or more analyte sensor data, receiving a reference measurement value associated with an analyte level, determining a sensitivity parameter based on the received one or more analyte sensor data and the reference measurement value, performing a probability analysis based on prior analyte sensor data to determine presence of signal attenuation, and generating an output value based on the probability analysis.
Claims20
A method, comprising:
- determining one or more sensitivity values based on one or more retrieved stored analyte sensor data, one or more received analyte sensor data and one or more reference measurement values;
- determining a sensitivity parameter of an analyte sensor based on the determined one or more sensitivity values;
- and
- performing a probability analysis of the determined sensitivity parameter to determine a presence of a signal attenuation condition of the analyte sensor.
1 more element
An apparatus, comprising:
- an analyte sensor;
- a data communication interface;
- one or more processors operatively coupled to the data communication interface and in signal communication with the analyte sensor;
- and
- a memory for storing instructions which, when executed by the one or more processors, causes the one or more processors to determine one or more sensitivity values based on one or more retrieved stored analyte sensor data, one or more received analyte sensor data and one or more reference measurement values, determine a sensitivity parameter of the analyte sensor based on the determined one or more sensitivity values, and perform a probability analysis of the determined sensitivity parameter to determine a presence of a signal attenuation condition of the analyte sensor.
