Synonyms Toxocara Antibody, IgG; Toxocariasis Serology;
Additional information A titer of 1:32 or greater is indicative of infection at some time with Toxocara spp. Approximately 75% of patients with clinically diagnosed visceral or ocular larva migrans have titers to Toxocara canis of 1:32 or greater.

Specificity at titers of 1:32 or greater is 95%. Subclinical infection with Toxocara spp. is widespread, and titers of 1:32 or greater may be obtained in the serum of up to 10% of apparently normal persons. Titers of less than 1:32 are reported because of their possible value in assessing ocular infections, but must be interpreted with caution because of increased numbers of false positive reactions
