Frequently asked questions

In which conditions is IgM immunoblot (≥2 of 3 bands) altered?

In the OSMF atlas IgM immunoblot (≥2 of 3 bands) is reported in Lyme Disease. It is elevated in 1 across 1 entries.

Is there a standard clinical test for IgM immunoblot (≥2 of 3 bands)?

The atlas entries for IgM immunoblot (≥2 of 3 bands) 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 IgM immunoblot (≥2 of 3 bands) 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.
