Serum Lysozyme (LYSO)

Lysozyme is part of the normal immune defense mechanism. Named for its role in dissolving bacterial cell walls. In the human body, it is present in neutrophils, monocytes and macrophages; it is also present in mucosal secretions and is one of the surface defense factors. In patients with acute lymphoblastic leukemia, the serum lysozyme tends to rebound when the disease is relieved and the blood picture is improved. The determination of serum lysozyme is a good indicator for the treatment of leukemia, often combined with urine lysozyme.
