Measures CD64 protein on monocytes/macrophages to detect immune activation, often indicating infection or inflammation.
What is a CD64 (Monocytic Macrophage Marker) Test?
The CD64 (Monocytic Macrophage Marker) test measures CD64 protein on monocytes and macrophages in the blood. CD64 helps immune cells bind antibodies and clear bacteria. Measuring CD64 shows how activated these immune cells are. It is useful for detecting bacterial infections and sepsis and for monitoring inflammatory or autoimmune conditions. Doctors use it alongside other tests and symptoms to guide treatment decisions. High CD64 often indicates bacterial infection or strong inflammation. Low or unchanged CD64 can suggest viral illness or immune suppression. Trends over time help track recovery or response to therapy.
