Dengue IgG and IgM Rapid Test
The Dengue IgG/IgM rapid test is a blood test used to detect antibodies against the dengue virus.
It helps determine whether a dengue infection is recent or past.
🧬 How It Works
IgM antibodies
Appear 4–7 days after infection
Indicate recent or acute dengue infection
Usually last 1–3 months
IgG antibodies
Appear after IgM (about 7–14 days)
Indicate past infection or secondary infection
Can persist for years
The test uses a rapid immunochromatographic strip, giving results in 15–20 minutes.
📊 Interpretation
Result | Meaning |
|---|---|
IgM positive, IgG negative | Early/primary dengue infection |
IgM positive, IgG positive | Current infection, possibly secondary infection |
IgM negative, IgG positive | Past dengue infection or late stage of current infection |
IgM negative, IgG negative | No detectable dengue infection (may be too early) |
⚠️ Timing is crucial: testing too early (<4 days of fever) may give false-negative IgM.
🩺 Symptoms of Dengue Fever
Sudden high fever
Severe headache
Pain behind eyes
Muscle and joint pain
Rash
Nausea/vomiting
Bleeding tendencies in severe cases
💡 Key Points
Rapid tests are useful for early triage, but not definitive in the first 3–4 days.
NS1 antigen test is preferred in the first week of fever.
Confirmatory tests (ELISA or PCR) may be needed for accuracy.
