This blood test detects antibodies that can help identify the parasitic disease filariasis. 

Filariasis is caused by infection with parasitic worms of the Filaridea family.  Filaria is most commonly spread by insects that feed on blood such as mosquitoes, gnats, and ticks.  Filarial parasites typically infect the lymphatic system which is responsible for transporting waste from the body and fighting infections.  Most infections can take months or longer to show any symptoms.  Some people may experience a rash or swelling around the lymph nodes.  The most common symptoms of chronic infection are a thickening of the skin and swelling, most often in the legs.  Swelling in other parts of the body can occur depending on where the infection is present.

Patients will be required to submit a medical history and travel history for this test.
