Macrophage Count in Body Fluids

Why Is This Test Done?

Doctors may order this test to evaluate immune responses, check for infections (such as abscesses or certain cancers), or monitor conditions like chronic inflammation or autoimmune diseases. It can also help diagnose or monitor diseases affecting macrophage function, such as certain infections or immune disorders.

How Is the Sample Collected?

A healthcare provider will collect a sample of body fluid, such as blood plasma, serum, or another fluid like cerebrospinal fluid or synovial fluid, depending on the clinical indication. The sample is then sent to a lab for analysis.

What Does the Test Result Mean?

Results are typically reported as a count of macrophages per unit volume of fluid. Elevated levels may indicate an active immune response or infection, while very low levels could suggest immune suppression or certain diseases. Interpretation depends on clinical context and other test results.

Common Conditions Monitored or Diagnosed

This test may be used to diagnose or monitor conditions like localized infections (e.g., abscesses), certain cancers (e.g., lymphoma), chronic inflammatory diseases, or immune system dysfunctions. It can also help assess the body’s response to treatments targeting macrophages.
