1. A test strip for use with a photometer for determining blood glucose concentration from a blood sample, said strip comprising:

  • a substrate having a top surface and an opposing bottom surface, said substrate having an aperture formed therethrough, said aperture being adapted to receive and receiving a droplet of blood;

    a porous membrane having a top surface and an opposing bottom surface, said top surface of said membrane adhered to said bottom surface of said substrate so that said membrane is in registration with said aperture in said substrate, said porous membrane filters red blood cells from plasma in said blood; and

    a reagent carried on said bottom surface of said membrane, the interior of said membrane being substantially free of said reagent, said reagent reacts with glucose in blood plasma.
