A visual blood glucose test strip (10), comprises: a) a spreading layer (12) for accepting a blood sample on a major surface and passing the sample to a second major surface, opposite; b) an intermediate layer (14) comprising first and second membranes (14a,14b), substantially side-by-side, each having a top major surface adjoining the second major surface of the spreading layer (12) to receive a part of the blood sample and each containing a reagent that can react with glucose in the sample, as it passes through the membrane, to cause a color change in the reagent, the second membrane further comprising an inhibitor and a dye, and c) a support layer (16) to support the other layers (12,14) and to permit any color changes in the membranes to be visible through it. <IMAGE> |
