Toxocara Antibodies, IgG by ELISA
Use
The Toxocara Antibodies, IgG by ELISA test aids in the diagnosis of toxocariasis caused by infection with Toxocara canis, a parasitic roundworm. This test is critical for identifying IgG antibodies specific to Toxocara, which can indicate current or past infection. The presence of these antibodies suggests exposure to the parasite, which can cause a range of symptoms in humans. This information is vital for clinicians in diagnosing and differentiating toxocariasis from other parasitic infections.
Special Instructions
The test is New York state approved and should be performed using the proper collection and transport methods. It is important to ensure specimens are not contaminated, heat-inactivated, or grossly hemolyzed, as these conditions can lead to inaccurate results.
Limitations
The Toxocara Antibodies, IgG by ELISA test may yield false-positive results due to infections with other helminths. Therefore, it is essential to interpret positive results with caution and consider the patient's clinical history and other laboratory findings. Equivocal results should be re-evaluated by repeat testing in 2-4 weeks to confirm the presence or absence of Toxocara IgG antibodies.
