Abstract
Disclosed is an improved method for the preparation of test strips for the semiquantitative determination of glucose in aqueous fluids, e.g. urine. The test strips are comprised of a bibulous carrier impregnated with glucose oxidase, a substance having peroxidative activity and a water soluble iodide salt. The device is coated with the residue of a solution of a film forming material which, pursuant to the improvement disclosed herein, is obtained by saturating the strip with a solution containing about 1.75 to about 4.55 grams (g)/100 milliliters (ml) of ethyl cellulose in an appropriate solvent.
