ABSTRACT:
An easily grasped reagent strip is disclosed. The reagent strip includes a handle that is elevated or spaced from a flat surface on which the reagent strip is placed. The handle is formed or bent to extend laterally from the rest of the reagent strip. Alternatively, ribs or buttons may be formed in the handle of the reagent strip to space the handle from a flat surface. The reagent strip can also include informative tactile indicia such as braille to inform a visually impaired or blind person of the type of reagent strip and the location of the reagent pad on the strip.
