Serum/plasma mass concentration of C-C chemokine ligand 13 (CCL13)

Published: August 9, 2026Updated: August 16, 2026

This test measures the amount of CCL13, a protein involved in immune system responses, in your blood. It may be used to assess inflammation or immune function.

Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like chronic inflammation, immune disorders, or if you’re being evaluated for conditions such as certain infections, autoimmune diseases, or allergic reactions. It may also be part of a broader immune function assessment.

What Does the Test Involve?

A blood sample is drawn from a vein, usually in your arm. The sample is then processed to measure CCL13 levels using a specialized laboratory technique.

What to Expect Before the Test

No special preparation is typically required, but you may be asked to fast for a few hours if instructed by your provider. Wear comfortable clothing and plan to rest afterward.

What Are Possible Results?

Results are compared to a reference range specific to the test method used. Elevated levels may suggest increased immune activity or inflammation, while lower levels might indicate reduced immune signaling.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a high CCL13 level mean?
A high CCL13 level may indicate an active immune response, such as chronic inflammation, an ongoing infection, or an autoimmune condition. Your provider will discuss these findings in the context of your symptoms and medical history.
How is CCL13 tested?
CCL13 is measured using a blood sample processed through a technique called immunoassay, which detects and quantifies the protein in your plasma or serum.
Can CCL13 levels change with diet or exercise?
Diet or exercise may indirectly influence inflammation, which could affect CCL13 levels, but direct effects are not well-documented. Always follow your provider’s advice regarding test preparation.
