Quick highlights
- Indicates past dengue exposure pattern (IgG persistence)
- Not best for early acute dengue diagnosis
- Often interpreted with NS1 antigen and/or IgM based on illness day
- Timing from fever onset is critical for correct test choice
- No fasting; serum blood test
- Symptoms overlap with other viral fevers—clinician evaluation needed
- Commonly paired with CBC/platelets for dengue assessment
- Home blood collection available in many service areas
- Safety red flags clearly stated
- SEO coverage: dengue IgG test, dengue antibody test, dengue past infection

FAQs
It usually indicates past exposure; IgG can persist for a long time.
Not usually; NS1 antigen is often used early, while IgM becomes useful later.
No.
Yes, that is common; clinicians interpret with symptoms and other dengue markers.
NS1 antigen in early days; IgM/combined profiles later; clinician decides based on timing.
Yes; symptoms overlap; clinicians may order both tests and CBC.
Often same day or within 24 hours.
Serum blood sample.
Yes in many serviceable areas.
Follow clinician advice; NSAIDs are often avoided until dengue is excluded.
Bleeding, persistent vomiting, severe abdominal pain, drowsiness, or breathlessness—seek urgent care.
No, especially in early illness; timing and test selection matters.
