Distinguishing test types through spectral analysis

A method and apparatus for automatically selecting test types for an analytical meter system based on the insertion into the meter of a test element. The test element can be an analytical element, formed by a test strip with a fluid such as blood applied thereto; a control element, formed by a test strip with control fluid applied thereto; or a standard element, or a standard strip exhibiting known optical properties. By inserting the test element into the analytical meter system, optical properties are measured and the existence of relationships between the measurements are ascertained. Based on the existence or nonexistence of certain relationships, the proper test can be automatically selected by the meter without the need for user interaction. Advantageously, the results of the test can be classified and stored according to test type.
