Enzyme-Linked Immunosorbent Assay (ELISA)
Synonyms:

Quest test code 34168, FILAB
Clinical significance:
This assay detects Filaria IgG4 subclass antibody to enhance specificity without sacrifice of sensitivity.

Chronic infections manifesting as elephantiasis may not result in a significant IgG4 antibody response and cannot be ruled out by this test.
