A disposable reagent unit including a base strip (12) with a plurality of spaced holes (24, 18, 20, 22), a double face tape (32), a reagent and a lot identification paper in side-by-side adjacent relationship, a wick (38), and a cover strip with a hole for engagement with a diagnostic instrument quantitative of an analyte in a liquid such as glucose in blood. Blood is deposited in the blood bowl (28) and is wicked to the reagent (36) for subsequent color change or other detectable change to be measured by a diagnostic instrument. The color intensify of the reagent is proportional to the analyte such as glucose in the blood. A blood or fluid guard of a predetermined geometrical shape can be secured to the reagent unit to protect the diagnostic instrument from transmission of fluid, such as blood. Any particular portion of the surface of the diagnostic reagent unit can be covered by the blood or fluid guard so as to protect, shield and cover the predetermined surfaces of the diagnostic instrument. |
