Why This Test Might Be Ordered

Your healthcare provider may recommend this test if they suspect an immune-related condition, such as certain infections, autoimmune disorders, or responses to treatments like chemotherapy. It could also be part of a broader evaluation for conditions affecting inflammation or immune cell movement.

What to Expect Before the Test

No special preparation is typically needed. You may fast if instructed by your provider, but this test does not require fasting. Bring any medications or supplements you’re currently taking to your appointment.

What Happens During the Test

A healthcare professional will draw blood from a vein in your arm. The blood sample will be sent to a lab for analysis. The test measures CCL20 levels in your serum using a sensitive detection method.

What the Results Mean

Results are interpreted by your healthcare provider based on your overall health, symptoms, and medical history. Elevated levels may indicate an active immune response or inflammation, while lower levels might suggest reduced signaling in certain immune pathways.

Reference range

Reference values vary by assay platform and laboratory; consult the performing laboratory's reference range. Generally reported in pg/mL.N/A

Specimen: serum

No special preparation required. Fasting is not necessary.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Short name

Frequently asked questions

What could cause abnormal results?
Elevated CCL20 levels may be seen in conditions like certain infections (e.g., HIV, tuberculosis), autoimmune diseases, or during chemotherapy. Lower levels might be associated with suppressed immune signaling but can vary by individual health status. Always discuss results with your provider.
How often should this test be repeated?
Your provider will determine the frequency based on your condition and treatment plan. Some patients may need retesting if symptoms or treatments change, while others may only need a one-time measurement.
Does this test interact with medications?
CCL20 testing itself does not directly interact with medications, but certain immune-modulating drugs (e.g., biologics) or infections may influence results. Always inform your provider about all medications or supplements you take.
