Glucose testing strips for the Accutrend Plus meter system. The test strip consists of four different layers. The first layer contains a yellow mesh, impregnated with a surfactant as an application field. The second layer contains a glass fibre fleece that works as a separating layer for blood cells. The third layer is a reaction film in which the colour formation takes place. The forth layer is for support. On the reverse side you will find a bar code, which is read by the meter to confirm test strip identity, i.e. the lot number on the test strip is congruent with the stored code. A box contains 25 strips.
