  • Erythrocyte sedimentation rate control
    Patent number: 6342391
    Abstract: A three-phase suspension suitable for use as an erythrocyte sedimentation rate (ESR) control having the following three components: (1) a synthetic plasma base, (2) an aggregating agent such as a high molecular weight polymer or combination of high molecular weight polymers, and (3) chemically fixed mammalian red blood cells. The control is designed to allow the user to monitor the accuracy and precision of analytical methods for determining the sedimentation rate of human erythrocytes in whole blood specimens. Chemical fixing of the red blood cells provides the ESR control with the capability of providing useful results in the presence of citrate and/or saline.
