| 20090263827 | Method for determining health status by analyzing analytes - A method to extract information from samples taken at different times from a mammalian. These samples are analyzed with respect to one or more analytes giving one or more responses, creating one or more response curves. From this/these response curves is/are changes in the responses calculated as slope, curvatures or mathematical functions. This is especially useful for early detection of acute myocardial infarction. | 10-22-2009 |
