80208-2

LOINC code 80208-2 identifies "Leishmania infantum+donovani IgG Ab [Titer] in Serum or Plasma by Immunofluorescence". This assay detects antibodies against Leishmania donovani IgG 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 1:320 titer indicates no IgG class antibodies against Leishmania donovani are detected, but infection cannot be excluded. A reaction of a titer at 1:320 is positive indicating a former or acute infection. This term was created for, but not limited in use to, the submitter's Anti-Leishmania donovani indirect immunofluorescence test kit.

This code measures Leishmania infantum+donovani Ab.IgG 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.
