Dengue IgM Antibody Test

This test detects the presence of IgM antibodies against the Dengue virus, which are typically produced by the body in response to a recent infection.

Why consider this test?

IgM antibodies appear shortly after infection and are used to confirm acute Dengue virus infection. It can help differentiate Dengue from other illnesses with similar symptoms, such as Chikungunya or Zika.

Who should get this test done?

• Individuals suspected of having Dengue, especially those with a history of exposure in endemic regions.
• People with acute febrile illness, rash, or other symptoms of Dengue fever.

More Information

The Dengue IgM antibody test is a critical component of diagnosing acute dengue infections. If you exhibit symptoms of dengue or have been exposed to the virus, consulting with a healthcare provider about this test can help ensure prompt diagnosis and appropriate management. During a secondary dengue infection (suspected dengue infection in someone who was previously diagnosed with dengue fever or sometimes after non-dengue flavivirus vaccination or infection), antibody levels rise rapidly and react broadly against many flaviviruses.

IgG is at high levels, even in the acute phase, and persists for periods lasting from 10 months to life. evels are significantly lower in secondary infections than in primary ones and may be undetectable in some cases. IgM levels are significantly lower in secondary infections than in primary ones and may be undetectable in some cases.
