Systems and methods for optimizing detection of optical signals indicating the presence of an analyte of interest in a blood sample are described. In one aspect, a blood culture test vial having a sensor is inoculated with the blood sample, light at an excitation frequency of the sensor is transmitted to the test vial, an intensity of a plurality of fluorescence signals emitted from the test vial is measured, and the plurality of measured fluorescence signals are normalized using by a reference signal that is not dependent on a measured intensity of a fluorescence signal emitted from the test vial. In another aspect, a measurement system measures fluorescence signals from one or more reference vials performing in extreme pH conditions. Fluorescence signals emitted from test vials inoculated with samples under test are measured and compared to the signals measured from the one or more reference vials to address or mitigate variability in hardware components of the measurement system.

A glycemic management related analyte detecting assay device () and method are provided for detecting and quantifying analyte concentrations in a fluid sample. The assay device includes an absorbent body containing an assay forming a detection zone for receiving a fluid test sample. The absorbent body is provided in a chamber of the device. The assay can detect one or more of a glycemic analyte selected from the group consisting of fasting plasma blood glucose, oral glucose, % glycated hemoglobin, and fasting insulin concentrations. In one embodiment, a container includes an absorbent body having a plurality of superimposed membranes () where each membrane contains a reactant and a color indicator for detecting the presence of a selected analyte above a predetermined concentration in the fluid sample. The absorbent body and/or the assay include a color indicator that is able to provide a visual indication of the presence of one or more glycemic analytes present in the test sample.

Disclosed herein are systems and methods for a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes first and second working electrodes to measure additional analyte or non-analyte related signal. Such measurements may provide a background and/or sensitivity measurement(s) for use in processing sensor data and may be used to trigger events such as digital filtering of data or suspending display of data.

Dual electrode system for a continuous analyte sensor

A system and method is provided for a continuous glucose monitoring (CGM) system and the processing of data collected thereby. An internet gateway chip () is included in elements of a CGM system to facilitate direct data communication with cloud network storage () thereby communicate and store data of a CGM sensor () of the CGM system. The internet gateway chip can be included in a receiver (), such as an existing wireless receiver and display device of the CGM; in a smart phone or similar device, where the smart phone is also the wireless receiver and display device of the CGM; or in the sensor, such as an existing sensor and/or transmitter () of the CGM to facilitate direct data communication between the CGM system and cloud network storage.

Direct CGM connectivity to a cloud storage network

An optical analyte sensor and diabetes management system is provided. The sensor preferably includes a hydrogel matrix for receiving a sample containing an analyte at unknown concentration, a light emitter for emitting light at a stimulation frequency, a light receiver for receiving a fluorescence signal at a first isosbestic frequency, and at a second frequency, for measuring an intensity of the fluorescence signal and the first and second frequencies. A processor determines a concentration of the analyte based on the respective intensities.

System and method for dynamically calibrating and measuring analyte concentration in diabetes management monitors

An insulin delivery device () includes a cannula () for delivering insulin to a patient at an infusion site, a pump assembly (), and a valve () for controlling the flow of insulin. A removable leak detector unit () is coupled to the delivery device for sensing and detecting leakage of insulin at the infusion site. The leak detector unit () has electrodes () positioned for contacting the insulin leaking from the infusion site, a sensing electrical circuit () and a power source () for operating the leak detector unit. The removable leak detector unit () has an electrical contact () for mating with an electrical contact () of the delivery device for electrically and operatively connecting the leak detector unit () to the delivery device. The leak detector unit () sends a signal to the pump assembly () and/or valve () to stop the flow of insulin when leakage is detected at the infusion site.

Adhesive pad systems that provide longer lasting adherence of the mounting unit to the host's skin are provided. Some systems include a reinforcing overlay that at least partially covers the adhesive pad. The reinforcing overlay may be removable without disturbing the sensor so that the overlay may be replaceable.

Systems and methods for securing a continuous analyte sensor to a host

The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for transcutaneous measurement of glucose in a host.
