Abstract
The present invention provides a reference solution for use in instruments that determine hematocrit levels in biological samples by measuring the resistance and/or conductivity of the biological samples. A reference solution according to the invention achieves conductivities representative of known hematocrit levels in blood, while maintaining tolerable levels of interference with the measurement of other analytes in the reference solution.
