Abstract
A test strip with a sample chamber is secured to a meter. The sample chamber in the portion of the test strip that extends out of the meter is illuminated by transmitting light from a light source inside the meter internally through the test strip towards the sample chamber. By way of analogy, the test strip acts in a fashion similar to a fiber optic cable or optical wave guide by transmitting the light from the meter to the remotely located sample chamber that extends outside the meter. The user is then able to easily see the sample chamber of the test strip in dark conditions so that the user is able to readily align the sample chamber with the drop of fluid on the skin as well as view the sample chamber in order to ensure proper filling. The light also illuminates a test strip slot into which the test strip is inserted.
