Abstract: The present disclosure describes a continuous analyte monitoring system that may monitor, generate, and analyze data for analytes (e.g., glucose and/or lactate) and non-enzymes simultaneously. In certain aspects, an analyte sensor system includes a first electrode, a second electrode, and a sensor electronics module. The first electrode generates a first analyte signal stream. The second electrode generates a non-enzyme signal stream indicating a level of a non-enzyme over time. The sensor electronics module determines a level of a first analyte based on the first analyte signal stream and adjusts the level of the first analyte based on the non-enzyme signal stream.

Abstract: An apparatus includes an analyte sensor, a memory, and a processor. The processor monitors, using the analyte sensor, an analyte of a patient during a time period to obtain measured analyte data for the analyte and monitors other measured sensor data indicative of a physiological state of the patient during the time period. The processor also determines, based on the physiological state of the patient during the time period, expected analyte data for the analyte and determines a correction factor based on the expected analyte data and the measured analyte data. The correction factor is indicative of an error in calibration of the analyte sensor. The processor also determines whether recalibration of the analyte sensor is possible. If recalibration is possible, the processor recalibrates the analyte sensor based on the correction factor, and if recalibration is not possible, the processor recommends, to the patient, to replace the analyte sensor.

Abstract: The present disclosure relates to methods and systems for predicting glycemic events in a patient induced as a result of physical activity. In certain aspects, a method includes monitoring a plurality of analytes of the patient continuously during a time period to obtain analyte signals, the plurality of analytes including at least glucose and lactate. The method further includes processing the analyte data from the time period to determine signal-to-noise ratios of the analyte signal. The method then compares the signal-to-noise ratios to each other to determine if a sensor in the continuous analyte monitoring system is non-responsive. In alternative embodiments, a reference signal is obtained and a reference signal-to-noise ratio is compared to the analyte signal-to-noise ratio to determine if a sensor in the continuous analyte monitoring system is non-responsive.

Abstract: A method for predicting disease is provided. The method includes generating biased analyte data by adding analyte sensor bias to historical analyte data, associating the biased analyte data with clinical disease diagnoses associated with the historical analyte data, and extracting features from the biased analyte data. The method further includes, for each model of a number of models, generating disease predictions based on different combinations of the features extracted from the biased analyte data, and evaluating the disease predictions based on the clinical disease diagnoses associated with the biased analyte data. The method further includes selecting a model and a combination of features based on a performance metric and a robustness metric.

Abstract: The present disclosure describes a multi-analyte sensor system. The system includes a first sensor with a first enzyme for a first analyte, a second sensor with a second enzyme for a second analyte different from the first analyte, a potentiostat, a memory, and a processor communicatively coupled to the memory. The potentiostat applies a first voltage to the first sensor to cause a first current to flow through the first sensor and applies a second voltage to the second sensor to cause a second current to flow through the second sensor. The processor determines, based on the first current, a level of the first analyte and determines, based on the second current, a level of the second analyte.

Abstract: The present disclosure describes a multi-analyte sensor system that detects artifacts using multiple analytes. According to an embodiment, the multi-analyte sensor system includes a first analyte sensor, a second analyte sensor, and a sensor electronics module. The first analyte sensor produces a first analyte signal stream indicating a level of a first analyte. The second analyte sensor produces a second analyte signal stream indicating a level of a second analyte different from the first analyte. The sensor electronics module detects, based on the first analyte signal stream and the second analyte signal stream, at least one of a compression event or a dip and recover event and in response to detecting at least one of the compression event or the dip and recover event, make an adjustment related to at least one of the first analyte sensor or the first analyte signal stream based on the event.
