This serologic test (ELISA) detects IgG-class antibodies to Toxocara species and aids in the diagnosis of toxocariasis, including visceral larva migrans and ocular larva migrans. It helps identify current or past exposure, though antibody levels may remain elevated for years. A negative result typically rules out infection; however, clinical correlation, including eosinophilia and exposure history, is required since assay sensitivity varies by disease location and timing. False positives may occur with other helminth infections.
