About this test

This test looks for IgG antibodies against the dengue virus. IgG appears later than IgM and stays for years, so it shows a past infection or, when very high, a repeat (secondary) dengue infection.

Why is this test done?

  • Find past dengue infection
  • Identify a second dengue infection, which can be more severe
  • Read along with NS1 and IgM results

Symptoms — when should you get tested?

  • High fever
  • Body and joint pain
  • Pain behind the eyes
  • Rash or bleeding signs

Normal range

Dengue IgG Negative

Reference ranges differ slightly between labs, methods, age and sex. Always discuss your report with your doctor.

If your result is high

A positive IgG means you have had dengue before. If IgG is positive early in a fever, it may suggest a second infection that needs closer watch.

Common reasons
  • Past dengue infection
  • Current secondary dengue infection
