Abstract
Embodiments of the present invention encompass systems and methods for detecting the presence of a test pad on a test strip. Exemplary techniques involve receiving a test strip having at least one test pad, where individual test pads have a pad width with ink disposed on two ink zones at two opposing sides of the width of the pad, illuminating the at least one test pad with a light source, detecting reflected signals from the test pad, generating an image comprising of pixels of the two ink zones based on the reflected signals, detecting the presence of each of the ink zones by comparing the number of consecutive pixels against a predetermined threshold, and determining the presence of the test pad on the test strip if two ink zones are detected within the pad width.
