Absolute monocytes measures the count of monocytes (circulating precursors to tissue macrophages) per microliter of blood. Monocytes migrate into tissues to clear pathogens and dead cells.
Elevated monocytes signal chronic inflammation, infection, or smoldering systemic disease. Persistent elevation can indicate autoimmunity, chronic infection, or hematologic disorders. A useful tracking marker alongside the neutrophil-lymphocyte ratio.
Optimal Monocytes Absolute: 0.2-0.6 K/µL.
Typically re-tested every 12 weeks.
