80207-4

LOINC code 80207-4 identifies "Leishmania infantum+donovani IgM Ab [Titer] in Serum or Plasma by Immunofluorescence". This assay detects antibodies against Leishmania donovani IgM for L. infantum screening based on the known cross reactivity between L. donovani and L. infantum. If the Leishmania IIFT is positive, a monospecific test (example Westernblot) can be performed to differentiate the pathogenic agents and confirm the diagnosis. Immunoglobulin specific slides distinguish between IgG, IgM and IgA. No reaction at a 1:100 titer indicates no IgM class antibodies against Leishmania donovani are detected, but infection cannot be excluded. A reaction of a titer at 1:100 is positive indicating a former or acute infection. This term was created for, but not limited in use to, the submitter's Euroimmun Anti-Leishmania donovani indirect immunofluorescence test kit.

This code measures Leishmania infantum+donovani Ab.IgM in Ser/Plas. It belongs to the MICRO class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
