Michael F Tomasco, Maria Teodorczyk, Remedios Dato, Edward G Rice: Blood glucose strip having reduced side reactions. LifeScan, James Riesenfeld, April 15, 1997: US05620863 (168 worldwide citation)

A reagent strip for measuring glucose concentration in a biological fluid containing red blood cells has reduced interference of hematocrit with the glucose measurement. When a biological fluid contacts the strip, it causes, in a reagent impregnated in the strip, a color change which is a measure of ...
