Dengue IgG IgM (Rapid) - Comprehensive Medical Test Guide

Section 1: Why is it done?
- Test Purpose: Detects dengue virus antibodies (IgM and IgG) in blood serum using rapid immunochromatographic technique
- Primary Indications: Diagnosis of acute dengue fever infection; Differentiation between dengue and other febrile illnesses; Screening in endemic areas; Assessment of immune status
- Clinical Presentation Requiring Test: High fever; Headache and retroorbital pain; Muscle and joint pain; Rash; Bleeding manifestations; Thrombocytopenia
- Typical Timing: Within 3-5 days of symptom onset for IgM detection; After 5-7 days for improved IgM response; IgG appears in secondary infections or convalescent phase
Section 2: Normal Range
- Normal/Negative Result: IgM Non-Reactive (Negative); IgG Non-Reactive (Negative); Reported as "Negative" or "Non-Reactive" for both antibodies
- Positive Result: IgM Reactive (Positive); IgG Reactive (Positive); Reported as "Positive" or "Reactive" based on visual detection of colored band at specific test line
- Units of Measurement: Qualitative (Positive/Negative); Semi-quantitative scoring may be used (1+, 2+, 3+, or Negative/Weak/Strong); No numerical values reported
- Interpretation of Results: Negative/Non-Reactive: No dengue infection detected or very early infection (within first 3 days); Positive/Reactive: Dengue virus exposure or active infection indicated; Borderline/Weak: Repeat testing recommended
Section 3: Interpretation
- IgM Positive Only (IgG Negative): Indicates acute/recent primary dengue infection; Infection likely occurred within 1-2 weeks; Patient may still be in acute phase or early convalescence
- Both IgM and IgG Positive: Indicates secondary dengue infection or late primary infection; Prior dengue exposure confirmed; Higher risk for severe dengue manifestations
- IgG Positive Only (IgM Negative): Indicates past dengue infection/immunity; No acute infection present; Patient has previous dengue exposure with developed immunity
- Both IgM and IgG Negative: No dengue infection detected; Possible very early infection (first 2-3 days); Negative result does not exclude dengue; Repeat testing recommended if clinical suspicion remains high
- Factors Affecting Results: Time since symptom onset (critical factor); Timing of collection during infection phase; Individual immune response variation; Cross-reactivity with other flaviviruses (Zika, Yellow Fever); Test sensitivity/specificity (typically 85-98% for IgM, 95-100% for IgG); Quality of test kit and technical proficiency
- Clinical Significance Patterns: IgM presence indicates recent infection and active viral replication; IgG indicates immune memory and prior exposure; Rapid test results guide immediate clinical management; Confirmation with ELISA or RT-PCR recommended for critical decisions
Section 4: Associated Organs
- Primary Organ Systems Involved: Lymphoid system (lymph nodes, spleen); Blood and bone marrow; Endothelial system (vasculature); Liver (hepatic involvement); Central nervous system (rare); Kidneys and urinary system
- Medical Conditions Associated with Abnormal Results: Dengue Fever (Classic); Dengue Hemorrhagic Fever (DHF); Dengue Shock Syndrome (DSS); Thrombocytopenia; Hepatitis (dengue-associated); Encephalitis (rare neuroinvasive form); Myocarditis (cardiac involvement); Secondary bacterial infections
- Diseases Diagnosed/Monitored: Dengue virus infection (primary diagnosis); Classification of infection severity; Monitoring of immune response; Epidemiological surveillance; Post-vaccination antibody assessment
- Potential Complications Associated with Abnormal Results: Hemorrhagic manifestations (internal bleeding, mucosal bleeding); Plasma leakage syndrome (capillary permeability); Hypovolemic shock; Acute respiratory distress; Organ dysfunction (liver, kidney); Disseminated intravascular coagulation (DIC); Fatal outcomes in severe cases (DSS); Long-term sequelae including fatigue and neurological complications
Section 5: Follow-up Tests
- Recommended Follow-up Tests if Positive: RT-PCR (Reverse Transcription Polymerase Chain Reaction) for viral confirmation and serotype identification; Dengue ELISA IgM/IgG for quantitative confirmation; NS1 antigen testing for early infection; Viral culture (specialized labs only); Plaque Reduction Neutralization Test (PRNT) for serotype confirmation
- Laboratory Monitoring Tests: Complete Blood Count (CBC) - for platelet count and hematocrit monitoring; Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) - coagulation assessment; Liver Function Tests (AST, ALT, Bilirubin) - hepatic involvement; Renal Function Tests (Creatinine, BUN) - kidney involvement; Serum Electrolytes - for shock assessment
- Further Investigations if Negative with High Clinical Suspicion: Repeat testing at 5-7 days if initial test done within first 3 days; NS1 antigen testing for acute phase; RT-PCR testing; Differential diagnosis testing for other febrile illnesses (Malaria, Typhoid, Chikungunya)
- Monitoring Frequency for Ongoing Conditions: Daily monitoring in acute phase (high fever period); Every 2-3 days during critical phase (days 3-7); Every 3-5 days during convalescent phase; Weekly follow-up for severe cases; Post-infection follow-up as clinically indicated
- Related Complementary Tests: Chikungunya antibody testing (similar presentation); Zika virus serology (cross-reactivity concerns); Yellow Fever antibody testing (differential); Malaria blood film (endemic area differentials); Typhoid serology (febrile illness exclusion); Imaging studies (ultrasound, chest X-ray) as needed for complications
Section 6: Fasting Required?
- Fasting Requirement: NO - Fasting is NOT required for dengue rapid antibody testing
- Sample Collection: Can be collected any time of day; Fed or fasting state does not affect results; No special timing considerations
- Patient Preparation Requirements: Minimal preparation required; Inform healthcare provider of current symptoms and fever onset date; No special clothing needed; Standard venipuncture precautions apply
- Medications and Special Instructions: No medications need to be avoided before testing; Antipyretics may be taken as needed; Continue all regular medications unless specifically instructed otherwise; NSAIDs should be avoided if dengue hemorrhagic fever suspected (bleeding risk); Inform laboratory of anticoagulant use
- Pre-Test Considerations: Provide accurate symptom onset date for interpretation; Report any recent travel to dengue-endemic areas; Mention previous dengue history if known; Note any recent vaccinations; Rapid test can be performed at point-of-care or lab without pre-test fasting
