What Does This Test Measure?
The test looks for antibodies produced by your immune system in response to dengue virus exposure. These antibodies can appear days to weeks after infection or vaccination. The presence and level of these antibodies help determine if you’ve been infected or vaccinated, and whether you may have active or past infection.
Why Is This Test Ordered?
Your healthcare provider may order this test if you have symptoms like fever, headache, joint or muscle pain, nausea, or rash—common in dengue—but other causes are suspected. It may also be used to confirm a diagnosis in travelers or individuals with a history of dengue exposure.
What Should You Expect Before the Test?
No special preparation is needed. You’ll have a small needle inserted to draw blood from a vein in your arm. The process takes a few minutes. If you’re pregnant, have a bleeding disorder, or take blood-thinning medications, let your provider know before the test.
What Happens After the Test?
After blood is drawn, a bandage will cover the site. You can return to normal activities immediately. Results may take days to weeks to be ready, depending on lab processes.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results indicate past infection or vaccination, but they don’t always confirm active dengue. Antibody levels can vary—high levels may mean past infection, while low or rising levels could suggest recent exposure. This test is critical for diagnosing dengue in areas where the virus is common, especially in travelers or those with travel history.
Short name
