Microfilaria Antigen Test

Your doctor will ask you to get this test done if he/she suspects that you have symptoms of filariasis. 

Most individuals with filariasis may show no symptoms at all. However, some people may present with the following symptoms:

  • High fever
  • Chills
  • Body pain
  • Swollen lymph glands
• Swollen arms and legs
• Swelling of genitalia 
• Pain in the affected areas
• Abnormally thick skin with a warty appearance

Nothing special needs to be done before this test. However, tell your doctor if you are taking any medications or health supplements. 

If you are anxious about needles, please speak to your doctor or nurse so that they can make you feel relaxed before the test.

Microfilaria antigen test is performed on a blood sample that is obtained either by fingerprick or venipuncture - from a vein in your arm. 

After the test, you may get a temporary bruise at the needle insertion site - it is nothing to worry about. If you notice persistent discomfort, inform your doctor as soon as possible.

Normal results:

Normal test results will be stated as negative. This means that you may not have live adult worms in your system.
