Dengue IgG/IgM Antibodies – Rapid: A Quick Way to Detect Dengue Antibodies

Test Overview

The Dengue IgG/IgM Antibodies – Rapid test is a widely used dengue rapid test designed to detect two types of antibodies — dengue IgG and IgM — in the blood. This test plays a crucial role in diagnosing dengue infection, especially after the first few days of symptom onset when the virus may no longer be detectable through antigen tests. The test provides quick, on-the-spot results, making it ideal during outbreaks and in resource-limited or rural areas. It helps clinicians identify whether the infection is recent (IgM) or past/secondary (IgG), allowing for timely medical decision-making.

Purpose of Dengue IgG/IgM Antibodies – Rapid Test

This test helps detect the body’s immune response to dengue, assisting in clinical assessment and disease monitoring.

• Identifies dengue IgG and IgM antibodies in blood: IgM antibodies usually appear within the first week of infection, indicating an active or recent infection. IgG antibodies typically appear later and suggest past infection or secondary exposure to dengue virus.
• Complements antigen-based dengue rapid test results: When NS1 antigen tests are negative or done too late, this antibody test becomes important. It helps confirm dengue by checking the body’s immune response.
• Guides patient care during later stages of illness: By understanding the type and timing of antibodies present, clinicians can determine the infection phase and adjust treatment accordingly.

When to Get the Dengue IgG/IgM Antibodies – Rapid Test?

Timing matters for antibody detection. Testing too early may result in a false negative due to low antibody levels.

• Best done after 5–7 days of fever onset: IgM antibodies begin to rise around day 4 to 7. Testing during or after this window improves the accuracy of the dengue rapid test.
• If symptoms persist or worsen: Continued fever, fatigue, joint pain, or rash beyond the initial days may indicate dengue. The test helps identify immune response in such cases.
• If earlier NS1 antigen test was negative or inconclusive: When initial dengue rapid test results are uncertain, antibody testing provides additional confirmation, especially after the acute phase.

Who Should Get the Dengue IgG/IgM Antibodies – Rapid Test?

This test is ideal for people showing symptoms or living in high-risk areas during the dengue season.

• Individuals with suspected dengue symptoms for more than 5 days: Symptoms like persistent fever, headache, rash, and muscle pain require confirmation with antibody testing after the first few days of illness.
• People living in or returning from dengue-endemic areas: Residents of or travelers to regions with high mosquito activity—especially during monsoons—should be tested if symptomatic.
• Those with a history of dengue or suspected reinfection: The presence of IgG along with IgM can indicate a secondary infection, which often has a higher risk of complications and requires closer monitoring.

Procedure and Preparation for Dengue IgG/IgM Antibodies – Rapid Test

The test is simple, safe, and non-invasive. It doesn’t require any special preparations, making it highly accessible.

• No fasting or specific preparation required: You can eat and take your medications as usual before this test. It’s suitable for all age groups, including children.
• Blood sample collection via finger prick or vein: A small blood sample is collected, usually via a finger prick. The test is conducted using a rapid device (cassette or strip), with results ready in 15 to 30 minutes.
• Performed at home or in clinics/labs: The test can be done at hospitals, diagnostic centers, or even at home with proper professional assistance, offering added convenience during illness.

Components of DENGUE IgG/IgM ANTIBODIES – RAPID Test

This rapid diagnostic test includes two components to detect dengue-specific antibodies in human blood:

DENGUE IgM ANTIBODIES

• Detects IgM antibodies produced by the immune system in the early phase of infection (typically 3–5 days after symptom onset).
• A positive IgM result suggests a recent or active dengue infection.

DENGUE IgG ANTIBODIES

• Detects IgG antibodies, which appear later and may persist for months to years.
• A positive IgG result indicates a past dengue infection or a secondary/reinfection in endemic areas.

Together, the test helps differentiate between primary and secondary dengue infections.

Price of Dengue IgG/IgM Antibodies – Rapid Test

The cost of the dengue rapid test may vary based on your location, service provider, and sample collection method.

• Average price range across cities: The Dengue IgG/IgM Antibodies – Rapid test usually costs between ₹300 and ₹900. Government-regulated centers may offer lower prices, while private labs can be slightly higher.
• Factors influencing cost include provider type and test quality: Accredited diagnostic labs and hospital-affiliated testing centers may charge more due to better equipment, trained staff, and quality assurance.
• Availability of home collection services: If you opt for home sample collection, there may be an added convenience charge. Online healthcare platforms sometimes bundle services or offer discounts.
• Regional price control during outbreaks: During dengue surges, some states cap prices to ensure testing remains affordable. Karnataka has implemented such controls under the Epidemic Diseases Act.

Understanding Your Dengue IgG/IgM Antibodies – Rapid Test Result

Note: Always discuss your test results with a qualified healthcare provider to ensure accurate diagnosis and treatment.
