A method is provided for calibrating a noninvasive glucose monitor for prospective noninvasive glucose determination. Spectroscopic transflectance readings are measured on the patient's skin using a noninvasive glucose monitor. The patient's blood glucose level is measured with an invasive glucose monitor. The noninvasive and invasive measurements are correlated to form an individual algorithm for each patient. Preferably, the position of the patient's skin with respect to the probe of the noninvasive monitor is spatially adjusted while collecting the transflectance measurements such that multiple readings are taken on the patient's skin. The measurements are preferably taken over a period of time and over a plurality of glucose levels in the patient.

Disclosed are methods and apparatuses for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can also include a treatment dosing system to infuse or inject a treatment dose (e.g. insulin, dextrose, etc.) and provide glycemic control. The dose of the treatment drug may be based on the patient's calculated sensitivity to treatment dosing, for example. The dose of the treatment drug may be based on the concentration of the analyte or the average value for the concentration of the analyte and/or the rate of change of the value of the concentration of the analyte. Delivery of the treatment drug can be cut off if the determined analyte concentration indicates that continued delivery would be harmful to the patient.

Microvascular complications of diabetes mellitus are closely related to blood glucose levels and fluctuations. The Glycostator statistical package was created to allow patients and health care providers simple access to “glycemic indicators” which permit a “snapshot view” of the effectiveness of the patient's diabetes management program. Glycostator functions provide a simple way of enhancing the information already provided by home blood glucose monitoring devices. To this end, a set of new indices, including one called the Virtual A1c, are computed in a recursive fashion from blood glucose test results to provide a more meaningful day-to-day assessment of glycemic control. All indices can be made available at the meter user interface on request. The displayed indices allow patients to improve glycemic control by identifying problems with blood glucose control and lability that are less easily recognized in traditional blood glucose meter statistical packages. Virtual A1c emulates hemoglobin A1c continuously and provides better day-to-day assessment of long term glycemic control than does the traditional average blood glucose report. The method for computing each of these indices, including the Virtual A1c, allows for their implementation in commercial blood glucose monitors.

A device and method are provided for use with a noninvasive optical measurement system, such as a thermal gradient spectrometer, for improved determination of analyte concentrations within living tissue. In one embodiment, a wearable window is secured to a patient's forearm thereby isolating a measurement site on the patient's skin for determination of blood glucose levels. The wearable window effectively replaces a window of the spectrometer, and thus forms an interface between the patient's skin and a thermal mass window of the spectrometer. When the spectrometer must be temporarily removed from the patient's skin, such as to allow the patient mobility, the wearable window is left secured to the forearm so as to maintain a consistent measurement site on the skin. When the spectrometer is later reattached to the patient, the wearable window will again form an interface between the spectrometer and the same location of skin as before.

This invention for the glucose biosensor based on the new disposal contact lens provides a safe, convenient and non-expensive glucose sensing device. The sensing device disclosed herein provides an efficient and noninvasive solution for monitoring blood glucose.

A method for collecting optical data at two morphologically similar, substantially non-overlapping, and preferably adjacent, areas on the surface of a tissue, while the temperature in each area is being maintained or modulated according to a temperature program. The optical data obtained are inserted into a mathematical relationship, e.g., an algorithm, that can be used to predict a disease state (such as the diabetes mellitus disease state) or the concentration of an analyte for indicating a physical condition (such as blood glucose level). This invention can be used to differentiate between disease status, such as, for example, diabetic and non-diabetic. The method involves the generation of a calibration (or training) set that utilizes the relationship between optical signals emanating from the skin under different thermal stimuli and disease status, e.g., diabetic status, established clinically. This calibration set can be used to predict the disease state of other subjects. Structural changes, as well as circulatory changes, due to a disease state are determined at two morphologically similar, but substantially non-overlapping areas on the surface of human tissue, e.g., the skin of a forearm, with each area being subjected to different temperature modulation programs. In addition to determination of a disease state, this invention can also be used to determine the concentration of an analyte in the tissues. This invention also provides an apparatus for the determination of a disease state, such as diabetes, or concentration of an analyte, such as blood glucose level, by the method of this invention.
