Clinical Use Lysozyme plays an important role in a host's defense against microorganisms. Lysozyme concentrations are increased in patients with acute myelocytic leukemia with monocytic differentiation (FAB M4/M5). Concentrations may also be increased in patients with other leukemias, sarcoidosis, and infections such as tuberculosis. With sarcoidosis, lysozyme may be useful in monitoring disease and treatment.
