🦟 Chikungunya IgG Rapid Antibody Test
Parameter | Details |
|---|---|
Test Name | Chikungunya IgG Rapid Antibody Test |
Type | Rapid immunochromatographic assay (qualitative) |
Sample Required | Whole blood / serum / plasma |
Fasting Required | ❌ Not required |
Detection | Detects IgG antibodies specific to the Chikungunya virus |
Turnaround Time | 15–30 minutes |
Department | Infectious Diseases / Internal Medicine / Primary Care |
🔬 What Is Detected?
- This test identifies IgG antibodies, which are typically produced after several days to weeks following Chikungunya infection.
- IgG indicates past infection or long-term immune response, not an active or very recent infection.
🧭 When Is This Test Useful?
Clinical Scenario | Purpose |
|---|---|
Fever history weeks ago with joint pains | Determine if Chikungunya was the cause |
Recurrent/chronic joint pain or arthritis | Evaluate for post-viral arthritis linked to Chikungunya |
Epidemiological surveys | Population-level screening for past exposure |
Travel screening or retrospective diagnosis | For people returning from endemic areas |
📉 Interpretation
IgG Result | Clinical Meaning |
|---|---|
Positive | Past exposure to Chikungunya; long-term immunity likely |
Negative | No prior exposure or early phase of infection |
⚠️ Note: A negative IgG does not rule out early infection, as IgG appears later.
❓ What It Does Not Detect
- IgM (recent infection) – For suspected acute or ongoing cases, an IgM test or Chikungunya Combo Rapid Test is more appropriate.
- It does not measure antibody titer — it only gives a positive/negative result.
🔬 Tests Recommended Alongside
Test | Why |
|---|---|
Chikungunya IgM | To check for recent or acute infection |
CBC (Complete Blood Count) | To assess platelet count and WBC |
Dengue IgM/IgG, NS1 | Rule out dengue co-infection |
CRP / ESR | Assess systemic inflammation |
Rheumatoid Factor / ANA | If long-term joint symptoms persist |
🧪 Limitations
- May miss early infection (use IgM or RT-PCR in acute phase)
- Not useful in distinguishing reinfection vs past immunity
- False positives may occur due to cross-reactivity with other alphaviruses
