Dengue IgG

A Dengue IgG test detects IgG antibodies against the dengue virus in your blood. A positive result may indicate a past dengue infection, as IgG antibodies typically develop one to two weeks after initial exposure and can persist for years.

Dengue IgG: what this test measures

This test detects the presence of IgG antibodies directed against the dengue virus in your blood. IgG antibodies are produced as part of the immune system's later response to infection and indicate prior exposure to one or more dengue serotypes. The test provides a qualitative result indicating whether these antibodies are present.

Dengue IgG: why this value matters

Knowing your dengue IgG status is important because a secondary infection with a different dengue serotype may be associated with a higher risk of severe dengue. Understanding whether you have been previously exposed can help healthcare professionals assess your risk profile, particularly if you travel to or live in dengue-endemic regions.

Dengue IgG: when is testing worthwhile?

Testing may be recommended if you have previously lived in or travelled to dengue-endemic areas and want to know your exposure history, or if you are planning travel to such regions. Consult a healthcare professional for guidance.

Dengue IgG: lifestyle and this value

Protect yourself from mosquito bites when in dengue-endemic areas by using insect repellent, wearing long sleeves and trousers, and sleeping under mosquito nets. Eliminate standing water around your living area to reduce mosquito breeding. Seek prompt medical attention if you develop fever, severe headache, or joint pain after visiting an endemic region.

Dengue IgG: frequently asked questions

Can I get dengue more than once?
Yes, there are four different dengue serotypes. Infection with one serotype provides long-term immunity to that specific serotype but not to the others. A subsequent infection with a different serotype may be associated with an increased risk of severe dengue. Consult a healthcare professional for guidance.
Does a positive Dengue IgG result mean I am currently infected?
Not necessarily. A positive Dengue IgG result typically indicates a past infection rather than a current one. IgG antibodies can persist for years after the initial infection. If a current infection is suspected, additional tests such as Dengue IgM or NS1 may be recommended.
