About This Test

Who Is This For?

You're curious whether you've had dengue before — maybe you had a mystery illness months ago and never got tested, or you're arriving in a dengue-endemic area and want to know your baseline. This test answers one simple question: has your body ever fought off a dengue infection?

What Does This Test Measure?

The Dengue IgG antibody test detects long-term antibodies that persist after a dengue infection has resolved. Unlike IgM (which indicates a recent infection), IgG antibodies can remain in your blood for years — even for life. Knowing your IgG status is medically relevant because a second dengue infection can sometimes be more severe than the first, a phenomenon known as antibody-dependent enhancement.
