Most of the diseases of modern mankind involve either acute or chronic inflammation. "Measuring Immunity" integrates the current information available on biomarkers and surrogate assays into a single handbook. It highlights the principles behind various applications, gives a brief summary on how they are conducted and provides detailed and critical analyses of murine models of immunity, clinical trials, and tests to predict utility and benefit. "Measuring Immunity" is indispensable for scientists and clinicians interested in the clinical applications of modern immunobiology. It defines which assays of immune function are helpful in the assessment of clinical disorders involving inflammation and immunity. It assesses the dynamics of cellular and soluble factors in the peripheral blood using modern techniques. It includes basic science foundations as well as the approaches currently applied.
