Lysozyme in the serum is primarily due to the degradation of granulocytes and monocytes and its concentration reflects the turnover of these cells. Increases are seen in benign and malignant processes. Serum lysozyme is elevated in patients with acute or chronic granulocytic or monocytic leukemias and levels decrease with successful treatment. Conversely, patients with lymphocytic leukemia may have depressed plasma lysozyme levels.
Centrifuge serum specimens within 1 hour of collection. Transfer
serum to sterile, plastic, screw-cap vial. Delayed separation of the
serum can result in spuriously high levels of lysozymes, presumably
because of the breakdown of leukocytes.
