Filaria Antigen

FILARIA ANTIGEN This test is a highly sensitive diagnostic tool that detects circulating antigens produced by adult Wuchereria bancrofti parasites in blood, acting as an early marker for Lymphatic Filariasis. It is used to diagnose active infections causing symptoms like swelling (elephantiasis), fever, and lymph node inflammation.

The purpose of the test is to:

• Detect active filarial infection
• Identify parasite antigens in the blood
• Support early diagnosis of lymphatic filariasis
• Help guide timely treatment

FILARIA ANTIGEN Test

The Filaria Antigen test detects specific antigens produced by filarial parasites, which cause lymphatic filariasis. The infection is transmitted through the bite of infected mosquitoes and can affect the lymphatic system.

The test is useful for identifying an active filarial infection, particularly in individuals with symptoms or a history of exposure in areas where lymphatic filariasis is prevalent. Unlike antibody tests, antigen detection can provide evidence of the presence of adult filarial worms.

Filarial antigen testing may be performed alongside other investigations, such as blood smear microscopy, depending on the suspected parasite, timing of testing, symptoms, and clinical requirements.

This Test is Recommended for Individuals:

• Individuals with suspected lymphatic filariasis
• People with unexplained swelling of the legs, arms, breasts, or genital region
• Patients with recurrent episodes of fever associated with lymphatic swelling
• Individuals living in or travelling to areas where filariasis is prevalent
• People with suspected filarial infection based on clinical findings
• Patients requiring evaluation or monitoring of known filarial infection

FAQs

1. What does the Filaria Antigen test detect?
It detects filarial parasite antigens in the blood, helping identify an active lymphatic filarial infection.

2. What symptoms may suggest filariasis?
Symptoms can include fever, lymph node or lymphatic inflammation, and swelling of the limbs or genital region. Some infected individuals may have few or no symptoms initially.

3. Is the Filaria Antigen test the same as a filarial antibody test?
No. An antigen test detects substances produced by the parasite, while an antibody test detects the body's immune response to the infection. Antigen testing can be useful for identifying active infection.
