Abstract
A control solution for use with a porous reagent strip comprises a flexible semisolid polymer dispersed in water, such as polyvinyl acetate in distilled water, with appropriate control glucose concentration levels. This solution is useful in mimicking whole blood in conjunction with porous reagent strips to determine compliance of the strips and meters to established measurement and performance criteria.
Claims11
A control solution which mimics whole blood, for use with a porous reagent strip comprising:
- a suspension of about 40% to about 55% solid polyvinyl acetate particles dispersed in water, and a dispersant to maintain said particles in suspension and glucose.
A control solution for use with a porous reagent strip having about 0.8 micron diameter pore size, said solution mimicking whole blood on said strip, comprising:
- a 40%-55% polyvinyl acetate suspension and water in a ratio of between 1:5 and 1:8 by weight, a dispersant to maintain said polyvinyl acetate in suspension and glucose.
