Clinical Significance

Leishmania Antibody (IgG) - Detection of Leishmania IgG provides strong support for the diagnosis of visceral leishmaniasis. Some (but not all) patients with cutaneous leishmaniasis also have detectable serum levels of Leishmania IgG. Sera from patients with Trypanosoma cruzi infection (Chagas' disease) show significant cross-reactivity in the Leishmania IgG assay.

Test Details

Methodology

Enzyme Immunoassay (EIA)

Assay Category

This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by the U.S. Food and Drug Administration. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.

Reference Range(s)

<1.00

Interpretive Criteria

<1.00 Negative
≥1.00 Positive
This assay is intended to aid in the diagnosis of visceral leishmaniasis. Its use in diagnosing cutaneous leishmaniasis is limited, since a detectable antibody response is often absent in this form of the disease. Sera from patients with Chagas' disease (Trypanosoma cruzi infection) may be positive in this assay; thus, results should be used in conjunction with other clinical findings when considering a diagnosis of leishmaniasis.
