How do hematology analyzers work
WebBlood gas analyzers measure pH with a glass electrode and p CO 2 with a membrane-covered glass electrode (Stow-Severinghaus electrode). c tH + Ecf is calculated from pH, p CO 2, and c Hb (concentration of hemoglobin) using a model of the titration curve called the Van Slyke equation ( Table 1 ). WebThere are several types of tests used by blood analyzers, including cell counters for doing the blood counts, immunoassays for detecting antibodies, tests for ions that measure voltage differences, and tests for the presence of enzymes that detect enzyme activity by a physical change in the sample.
