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.

Methods and apparatus are provided for determining a diabetic patient's carbohydrate to insulin ratio (CIR), carbohydrate to blood glucose ratio (CGR), and insulin sensitivity factor (ISF) using the patient's record of blood glucose readings, carbohydrate consumption and insulin doses.

An apparatus that can collect and store the blood glucose readings, insulin dosages, and carbohydrate intake data and process these data according to this invention can generate statistically characterized sensitivity factors to advise the diabetic patient on optimal bolus insulin dosages.

A method for selectively combining multiple membranes for assembly into test strips (such as visual blood glucose test strips with side-by-side membranes). The method includes first measuring a plurality of color parameters (e.g., L*, a* and b*color parameters) associated with membrane samples from at least two membrane lots. Next, response characteristics (e.g., blood glucose response levels) are simulated for a speculative test strip that includes, for purposes of the simulation, combined multiple membranes tentatively selected from the at least two membrane lots. The simulated response characteristics are based on the measured plurality of color parameters of the tentative selection of combined multiple membranes. Optionally, the simulated response characteristics can also be based on simulated color parameters of the tentative selection of combined multiple membranes. Subsequently, assembly of the at least two membrane lots into a test strip with combined membranes is contingent on acceptable simulated response characteristics. Any suitable color parameters can be employed. The method can be used to selectively combine two or more membranes based on any number of color parameters. The assembled test strips can be used to measure glucose, cholesterol, proteins, ketones, phenylalanine or enzymes in blood, urine, saliva or other biological fluid, as well as sample fluid characteristics (e.g., pH and alkalinity).
