What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining whether you have a current dengue infection, past exposure, or no evidence of infection. These notes include personalized recommendations on symptom management, hydration strategies, warning signs to watch for, and whether you need immediate medical attention or follow-up care. You'll also get the standard lab report and can track your antibody levels over time using our trends feature, which is especially helpful if you're monitoring recovery or live in a dengue-endemic area.

When will I get my results?

Most dengue antibody test results are available within 1-3 business days after your sample reaches the lab. Quest Diagnostics processes these tests efficiently to help you get answers quickly when symptoms are present. You'll receive an email notification as soon as your results are ready to view in your secure online account.

Who should consider getting this test?

This test is important for anyone who has recently traveled to or lives in areas where dengue is common (Southeast Asia, Latin America, the Caribbean, Africa, or Pacific Islands) and is experiencing fever with severe headache, eye pain, joint pain, or rash. It's also useful for healthcare providers trying to distinguish dengue from other fever-causing illnesses, and for people who want to know if they've been previously exposed to dengue, which affects future risk.

What symptoms indicate I may need this test?

Common symptoms that suggest possible dengue infection include sudden high fever (often 104°F/40°C), severe headache with pain behind the eyes, intense muscle and joint pain (sometimes called breakbone fever), nausea, vomiting, swollen glands, and a rash that appears 2-5 days after fever starts. If you've been in a dengue-endemic area and experience these symptoms, testing can confirm the diagnosis and guide appropriate care.

What is dengue fever and why does it matter?

Dengue is a viral infection transmitted by Aedes mosquitoes that causes flu-like symptoms and can range from mild to severe. While most people recover within a week or two, some develop severe dengue (dengue hemorrhagic fever), which involves bleeding, plasma leakage, and organ damage requiring immediate hospitalization. Previous dengue infection can increase risk of severe disease with subsequent infections, making diagnosis and monitoring important for future health decisions.

What does a positive IgM result mean?

A positive IgM result typically indicates a recent or current dengue infection, as IgM antibodies appear within 3-5 days of symptom onset and can persist for several months. This finding confirms that your current symptoms are likely dengue-related and helps guide treatment decisions. Your doctor will focus on supportive care including rest, hydration, pain management with acetaminophen (avoid aspirin and NSAIDs), and monitoring for warning signs of severe dengue.

What does a positive IgG result mean?

A positive IgG result without IgM indicates past dengue infection or exposure, meaning you've been infected before, possibly without realizing it if symptoms were mild. IgG antibodies develop later in infection (after 1-2 weeks) and can last for years, providing some immunity. However, dengue has four different serotypes, and infection with one type doesn't fully protect against the others, so future infections are possible and may carry higher risk of severe dengue.

How can I protect myself from dengue fever?

Prevention focuses on avoiding mosquito bites in dengue-endemic areas by using EPA-registered insect repellents containing DEET, wearing long sleeves and pants, staying in air-conditioned or well-screened areas, and using mosquito nets. Eliminate standing water around your home where mosquitoes breed, such as in flower pots, buckets, and tires. If you're traveling to high-risk areas, consider the dengue vaccine if you've been previously infected, and be especially vigilant during early morning and late afternoon when Aedes mosquitoes are most active.
