Microfilaria Detection

What is the Microfilaria Detection Blood Test?

This test identifies microfilariae (larval forms of parasitic worms) in the blood, primarily used to diagnose filariasis, a mosquito-borne disease.


Who should get this test?

This test is recommended for:

Individuals with lymphatic swelling or elephantiasis.
People residing in or traveling to endemic regions.
Patients with unexplained fever, lymphadenopathy, or eosinophilia.



How is the test performed?

A blood sample is collected (preferably at night when microfilariae circulate) and examined using microscopic, antigen detection, or PCR techniques.


What do the results indicate?


Positive Result: Confirms active filarial infection.
Negative Result: Suggests no detectable microfilariae, but periodic testing may be needed.



Why is this test important?

Early detection helps prevent severe complications, such as lymphedema and hydrocele.
