A positive Lysozyme Viability Assay may be associated with acute leukemia, enteritis, or kidney damage. Lysozyme activity assay is a biochemical test that is divided into serum lysozyme assay and urine lysozyme assay. Lysozyme is a component of the normal body’s immune defense mechanism and has the effect of lysing bacterial cell walls. It can be found in human neutrophils, monocytes and macrophages; it can also be found in mucosal secretions. Generally speaking, lysozyme is not found in the urine of normal people. Positive serum lysozyme assay has differential significance for various types of acute leukemia, and is also an indicator of the activity of restrictive enteritis, which can assist in determining the severity of the disease or the effectiveness of treatment. Positive urine lysozyme assay is an indicator of renal tubular damage. 1. Acute leukemia: patients may have abnormally high neutrophils, which may result in positive intracellular lysozyme. 2. Enteritis: Damage to and inflammation of the intestinal mucosa leads to positive lysozyme in the mucosal secretions, which is indicative of the severity of the disease. 3. Kidney damage: damage to the renal tubules may result in a positive urine test for lysozyme. Therefore, if the examination of serum or urine lysozyme activity determination is positive, to cause patients to pay attention to further examination, to clarify the primary disease, as soon as possible to take symptomatic treatment, so as not to delay the treatment of the disease. Cause adverse consequences.
