Abstract: Provided is a technology useful for verifying measurement accuracy before measurement of an electrical characteristic of blood samples. A sample for use in electrical characteristic measurement is provided including erythrocytes incompletely fixed with a fixative, the fixed erythrocytes being such that an electrical characteristic of a mixture of the fixed erythrocytes and plasma components can change over time.
