DETECTING AND COLLECTING ANALYTE DATA
Establishing an analyte database using analyte data that has been obtained using one or more non-invasive analyte sensors, and using the analyte database to analyze data obtained using a non-invasive analyte sensor. Once the analyte database is established, the analyte database can be updated with new analyte data, and the analyte database can be used to analyze the new analyte data to derive information from the new analyte data. For example, in the case of a human target, the new analyte data together with the analyte database can be used to predict an actual or possible abnormal medical pathology of the human target.
