Abstract
A blood analyte measurement system is configured to receive a test strip. An LED proximate to the test strip is used to illuminate the test strip and, in conjunction with a photodiode, to determine its type. A compensation circuit of the measurement system insures that ambient light does not cause interference with the LED illumination to prevent saturation of the photodiode.
