  • Electrochemical determination of hematocrit
    Patent number: 4699887
    Abstract: A method for measuring hematocrit is provided. An electrochemically detectable marker is measured before and after the ratio of red cell volume to plasma volume is decreased. The measured concentrations are used in a mathematical formula to determine hematocrit value.
    Type: Grant
    Filed: March 24, 1986
    Date of Patent: October 13, 1987
    Assignee: E. I. Du Pont de Nemours and Company
