Test:Toxocara Ab(Screening)
Other Test Request Name:

Toxocara Antibody Screening

Test Composition:

Not applicable

Intended Use:

Utilizes the excretory-secretory(es) antigen ofT. canis larvaeto minimize cross-reactivity with antigens ofAscaris spp.and of other parasites. Results must be interpreted with caution as broad variations in antibody response occur and levels may remain elevated for years after infection. Generally, antibody levels are highest in visceral larva migrans (VLM). A negative result usually rules out infection withToxocara spp.

Intended Use:

Aids in the diagnosis of toxoplasmosis

The test is used for the detection of IgM antibodies to Toxoplasma gondii.

T. gondiiIgM is typically detected within a few days of infection, peaks within a few weeks, and usually falls to undetectable levels within a few months. In some patients, however,T. gondiiIgM persists for more than a year; Thus, detection ofT. gondiiIgM does not necessarily indicate recent or ongoing toxoplasmosis.
