Filaria Antigen Detection is a blood test that detects specific antigens produced by filarial worms, which cause lymphatic filariasis. The test is used to identify an active filarial infection, including infections that may have few or no symptoms. It is particularly helpful when evaluating symptoms such as swelling of the limbs or genital area and may support diagnosis and treatment decisions alongside clinical findings and other investigations.
Filariasis is a parasitic infection caused by filarial worms. Lymphatic filariasis can affect the lymphatic system and may cause swelling of the limbs or genital area.
Lymphatic filariasis is transmitted through the bites of infected mosquitoes. The parasite enters the bloodstream and develops within the body.
A positive result indicates that filarial antigen has been detected and supports the presence of an active filarial infection. Clinical evaluation is still important.
A negative result means the specific antigen was not detected. However, depending on the test used and timing of infection, further evaluation may sometimes be required.
Yes. Many people with lymphatic filarial infection may have few or no obvious symptoms, particularly during earlier stages.
