Frequently asked questions

In which conditions is CCL19 altered?

In the OSMF atlas CCL19 is reported in Lyme Disease. It is elevated in 1 across 1 entries.

Is there a standard clinical test for CCL19?

The atlas entries for CCL19 do not carry a LOINC code, which usually means the marker was measured with research assays or study-specific methods rather than a routine clinical panel.

Is one abnormal CCL19 result diagnostic?

No single biomarker result is diagnostic of any of these conditions. Findings reflect group averages from published cohorts with substantial overlap between patients and controls.
