Chemokine (CC motif) ligand 11, Serum or Plasma
This test measures the level of a protein called chemokine CCL11, which plays a role in attracting certain white blood cells to areas of inflammation or infection in your body.

What Does CCL11 Measure?
CCL11 is a small protein (chemokine) that signals immune cells to move toward sites of inflammation, allergies, or tissue damage. Elevated levels may suggest conditions involving chronic inflammation, allergic reactions, or certain immune disorders. This test is often used in research or specialized clinical settings to assess immune responses.
Why Might You Need This Test?
Your healthcare provider may order CCL11 testing if you have symptoms or conditions linked to immune cell recruitment, such as allergic reactions, certain cancers, or chronic inflammatory diseases. It may also be used in research or advanced diagnostic scenarios.
Sample Collection and Preparation
A blood sample is drawn from a vein in your arm. The blood is then separated into serum or plasma (the liquid part without or with clotting factors) for testing. This sample is sent to a lab for analysis using specialized techniques to measure CCL11 levels.
What Does a Result Mean?
Interpreting CCL11 results involves comparing your level to what is typically found in healthy individuals. While reference ranges can vary by lab, higher-than-normal levels may indicate increased immune activity, while lower levels might suggest reduced signaling in immune responses.
Reference range
Reference ranges vary by assay platform and laboratory; consult the performing laboratory's reference interval for accurate interpretation.N/A
No special patient preparation required. Specimen may be collected at any time of day as fasting is not required.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
