Methods of Lag-Compensation for Analyte Measurements, and Devices Related Thereto
First Claim
1. A method of lag compensation of glucose level measurements, comprising:
- receiving one or more uncompensated glucose measurements prior to lag compensation;
determining a first set of weighting coefficients from a glucose level corresponding to measurements at an initial reference time and at least two scaled rates-of-changes from the initial reference time to a first prior reference time and a second rate-of-change from the initial reference time to a second prior reference time; and
calculating lag-compensated glucose level measurements from the uncompensated glucose measurements by applying the first set of weighting coefficients to corresponding uncompensated glucose measurements received at the initial reference time, the first prior reference time, and the second prior reference time of the first parameter values.

Abstract
In some aspects, methods of lag compensation of analyte measurements are provided. Methods of lag-compensation are provided for analyte point measurements and/or for analyte rate-of-change measurements. The methods include receiving a series of uncompensated analyte measurements and determining parameter values for analyte point and/or rate-of-change estimates based on reference analyte measurements. The analyte rate-of-change estimate is based on a sum of a plurality of scaled rates-of-changes. The analyte point estimate is based on a sum of an analyte point and a sum of a plurality of scaled rates-of-changes. Devices related to the methods are also provided.
