WebThe number reported under Hemolysis on our chemistry panels is a semi-quantitative measurement of the concentration of free hemoglobin in mg/dL. The image to the right shows a visual representation of how these values correspond to visible hemolysis in plasma samples and the table below correlates the index value to this gross appearance. WebThe hemolytic assays form the initial approach to complement testing. These assays—originally applied to CH50 and AH50—use red blood cells (RBCs) and evaluate cell lysis, which is the end-product of the complement activation. To assess total complement function, or CH50, sheep erythrocytes are sensitized with antisheep antibodies.
