Overview
The purpose of the Dengue Fever Antibodies IgG & IgM ICT Test is to detect the presence of IgG and IgM antibodies produced by the immune system in response to Dengue Virus infection. This test aids in the early diagnosis of dengue fever, helps differentiate between primary and secondary dengue infections, and supports clinical decision-making for appropriate patient management. It is particularly useful in endemic areas and during dengue outbreaks for rapid screening and surveillance.

Sample Collection
No special preparation is required. Inform the healthcare provider about any current medications, recent vaccinations, or travel history. No fasting is necessary.
Method: Venipuncture
Laboratory Analysis
A trained phlebotomist will collect approximately 2 mL of blood from a vein in the arm using standard venipuncture technique. The blood is collected into a serum separator tube (SST). The procedure typically takes less than 5 minutes.
Report Delivery
Apply gentle pressure to the puncture site with a cotton ball or bandage. Mild bruising may occur and typically resolves within a few days. You can resume normal activities immediately after sample collection.
Timeline: Same day to 24 hours

About This Test
Who Should Get This Test
The purpose of the Dengue Fever Antibodies IgG & IgM ICT Test is to detect the presence of IgG and IgM antibodies produced by the immune system in response to Dengue Virus infection. This test aids in the early diagnosis of dengue fever, helps differentiate between primary and secondary dengue infections, and supports clinical decision-making for appropriate patient management. It is particularly useful in endemic areas and during dengue outbreaks for rapid screening and surveillance.
How to Prepare
- No fasting or special dietary restrictions required before sample collection
- Inform the phlebotomist about any history of bleeding disorders or anticoagulant medications
- Ensure the sample is properly labeled with patient details
- Serum must be separated from clot within 2 hours of collection
- Ship refrigerated at 2 to 8 degrees Celsius or frozen at minus 20 degrees Celsius if transport is delayed
Doctor's Notes
Reviewed by Dr Kothari Ramesh Shantilal — MBBS, MD (Microbiology) · Reg. No. 27670
"Dengue fever remains a significant public health concern in tropical and subtropical regions including India. The IgG and IgM ICT test is a valuable rapid screening tool that helps clinicians differentiate between primary and secondary dengue infections. IgM antibodies typically appear 3 to 5 days after symptom onset, while IgG antibodies appear later and may indicate past infection or secondary exposure. Early detection through serological testing supports timely clinical management and helps prevent progression to severe dengue, including dengue hemorrhagic fever and dengue shock syndrome. I recommend this test for patients presenting with acute febrile illness, especially during monsoon seasons or in endemic areas. This test should always be interpreted alongside clinical findings and, where possible, confirmed with NS1 antigen testing or RT-PCR for definitive diagnosis."

Test Parameters & Specifications
Sample Stability
- Hemolyzed, lipemic, or heavily contaminated samples
- Samples collected in incorrect tube type (not SST)
- Unlabeled or mislabeled specimens
- Samples exceeding stability time limits at the storage condition used
- Clotted blood in anticoagulant tubes or insufficient sample volume (less than 1 mL)
Understanding Your Results
No detectable antibodies. May indicate no current or past dengue infection, or testing performed too early in the infection (within 1 to 2 days of symptom onset). Repeat testing after 5 to 7 days if clinical suspicion persists.
Does not rule out acute dengue; consider NS1 antigen test or RT-PCR
Likely primary (first) dengue infection in the acute phase. IgM antibodies appear 3 to 5 days after symptom onset.
Supports diagnosis of acute primary dengue infection. Monitor for warning signs of severe dengue.
Could indicate late primary infection or early secondary infection. Both antibody classes are present.
Requires clinical correlation. Consider NS1 antigen and RT-PCR for further evaluation. Monitor closely for complications.
May indicate past dengue infection with resolved illness, or secondary infection where IgM has declined. IgG can persist for years.
Past infection or secondary infection. If acute symptoms are present, consider confirmatory testing with paired sera or RT-PCR.
Consult a doctor immediately if you experience high fever with severe headache, pain behind the eyes, severe joint and muscle pain, skin rash, bleeding from gums or nose, persistent vomiting, abdominal pain, or signs of dehydration. Seek urgent medical attention if there are warning signs of severe dengue, including lethargy, restlessness, rapid drop in platelet count, or fluid accumulation. Patients with a history of prior dengue infection who develop symptoms again should seek early medical evaluation, as secondary infections carry a higher risk of severe disease.
Limitations
- ⚠This is a qualitative screening test and does not quantify antibody levels; follow-up with quantitative ELISA may be needed
- ⚠Cannot differentiate between active and past infection based on IgG alone
- ⚠Cross-reactivity with other flavivirus infections is possible and requires confirmatory testing
- ⚠RT-PCR or NS1 antigen testing is recommended for definitive early diagnosis within the first 5 days of illness
- ⚠A single positive IgM or IgG result should be interpreted alongside clinical findings and epidemiological context
- ⚠Negative results do not rule out dengue infection, especially if tested very early in the disease course
Risks & Considerations
- ●Mild pain or discomfort at the blood draw site
- ●Minor bruising or hematoma at the venipuncture location
- ●Rarely, slight dizziness or lightheadedness during blood collection
- ●Very rare risk of infection at the needle puncture site
Interfering Factors
- ●Very early infection (within first 2 days of symptom onset) may yield false-negative results as antibodies may not yet be detectable
- ●Cross-reactivity with other flaviviruses such as Zika Virus, Japanese Encephalitis Virus, Yellow Fever Virus, and West Nile Virus may produce false-positive results
- ●Immunocompromised patients may have delayed or reduced antibody response leading to false-negative results
- ●Hemolyzed, lipemic, or contaminated serum samples may interfere with test accuracy
- ●Prior dengue vaccination (e.g., Dengvaxia) may result in positive IgG results regardless of active infection
