Abstract

To ensure accurate glucose readings when dispensing glucose oxidase enzyme solution from a jetting dispenser onto glucose test strips fabricated from an immersion gold-plated printed circuit board, every drop of the enzyme solution needs to have nearly the same weight and to be dispensed on the reaction zone of the test strips. Experimental results in this study show that the filling pressure in the fluid reservoir containing the glucose enzyme solution to dispense onto the test strips significantly affect the glucose test results. A filling pressure of 12 psi produces test strips with lower coefficient of variation and standard deviation than 10 and 14 psi. Proper filling pressure for dispensing glucose enzyme onto glucose test strips needs to be determined for any enzyme compound formulation. [ABSTRACT FROM AUTHOR]
