Filaria Antibodies Panel, IgG & IgM

The Filaria Antibodies Panel, IgG & IgM test detects immunoglobulin (IgG and IgM) antibodies against filarial parasites. This test helps determine if an individual has a recent filarial infection (shown by IgM antibodies) or if they have been exposed to the parasite before (shown by IgG antibodies).

Filarial infections (filariasis), caused by parasitic worms of the Wuchereria bancrofti, Brugia malayi, and Brugia timori species, are a significant public health concern in tropical and subtropical regions of the world. These infections are transmitted by mosquitoes and can lead to lymphatic filariasis, a debilitating disease that causes severe swelling of the limbs, scrotum, or breasts, often referred to as elephantiasis. In many cases, the infection can be asymptomatic or present with mild symptoms, making early diagnosis difficult without specific laboratory testing.

The Filaria Antibodies Panel, IgG & IgM helps detect two types of antibodies—immunoglobulin G (IgG) and immunoglobulin M (IgM). IgG antibodies generally indicate past exposure to the parasite, as they remain in the blood for extended periods, even after the infection is no longer active. Conversely, IgM antibodies are produced in response to recent or active infections and can help identify individuals currently affected by filarial parasites.

This panel is particularly recommended for individuals with symptoms such as swelling in the limbs, scrotum, or breasts, fever, or recurrent episodes of lymph node inflammation, which may be suggestive of lymphatic filariasis. It is also useful for individuals living in endemic areas or those who have traveled to regions where filarial infections are common. Furthermore, the test can help differentiate between a recent or ongoing infection and a past exposure, guiding appropriate treatment strategies.

No special preparation is needed for the Filaria Antibodies Panel, IgG & IgM. However, it is important to inform the doctor about any medications, supplements, or medical conditions before the test, as these factors may potentially influence the test results.

Lab test results may vary across laboratories. Abnormal test results require an expert interpretation. Therefore, never try to self-medicate at home based solely on these results. Always consult a doctor for a proper understanding of the test results. The insights provided by the test can help doctors develop an appropriate management plan, especially for those living in endemic regions or who may be at higher risk of infection.
