Dengue Virus Profile Rapid - IgG, IgM, NS1 Antigen - Immunochromatography
Also Known As
Test Parameters Included
- Dengue NS1 (Non-Structural Protein 1) Antigen: Detects a specific structural protein secreted into your blood by the replicating Dengue virus. This marker is highly critical because it appears almost immediately—from Day 1 to Day 5 of your very first fever symptoms—allowing for early detection before your body even begins manufacturing antibodies.
- Dengue IgM (Immunoglobulin M) Antibody: Measures the primary, immediate-response antibodies produced by your immune system to fight the active virus. IgM levels typically rise around Day 4 to Day 5 of the fever, peak within a couple of weeks, and gradually fade away over a few months.
- Dengue IgG (Immunoglobulin G) Antibody: Measures long-term protective antibodies. In a primary (first-time) dengue infection, IgG develops slowly after the first week and stays in your system for years to provide long-term protection. However, in a secondary (repeat) dengue infection, IgG levels skyrocket instantly within the first few days, serving as a vital warning sign for secondary complications.

Frequently Asked Questions
Why does the Dengue Profile report take 6 hours?
While the physical immunochromatographic strip reacts quickly, our diagnostic workflow incorporates formal sample clotting, centrifugation, double-blind verification loops, and immediate pathodiagnostic validation to ensure total accuracy before releasing critical files.
Why does this profile look at three different markers at the same time?
Testing NS1, IgM, and IgG together closes the "diagnostic gap." If we only checked antibodies, we would miss an infection in the first 3 days. If we only checked the NS1 antigen, we would miss an infection in a patient coming in on Day 8.
What is the "Diagnostic Window" for the NS1 Antigen?
The NS1 antigen is a marker of active viral replication. It is highly sensitive during the first 1 to 5 days of your fever. After Day 5, as your immune system builds antibodies, the NS1 protein naturally disappears from your blood.
Can I have Dengue if my rapid test comes back completely negative on Day 1?
If your symptoms are severe, yes. A negative result on Day 1 can occasionally happen if the viral load is still multiplying. Repeating the test or running a CBC to check platelet paths within 24–48 hours is highly recommended if a fever persists.
What makes a secondary (repeat) Dengue infection more dangerous?
There are four different types (serotypes) of the dengue virus. If you catch a second, different type later in life, your old IgG antibodies cannot neutralize it. Instead, they can accidentally help the new virus enter your immune cells faster, a process called Antibody-Dependent Enhancement (ADE).
Do I need to fast before coming in for my blood draw?
No, fasting is completely unnecessary for a standalone rapid dengue profile. You can have your sample drawn comfortably at any time of day or night.
Why does my platelet count drop during a Dengue infection?
The dengue virus can temporarily suppress your bone marrow (where platelets are made) and prompt your immune system to mistakenly destroy healthy platelets, which increases the risk of bleeding.
Can a standard mosquito bite cause a false-positive result?
No. The test reacts strictly to specific proteins produced by the Dengue virus itself. A regular mosquito bite without the underlying virus will not trigger a positive line.
What is the treatment if my Dengue profile comes back positive?
There are no specific antiviral drugs for dengue. Treatment is entirely supportive, focusing on staying highly hydrated with oral rehydration solutions, resting, and managing fever safely under medical supervision.
Why should I avoid taking aspirin or ibuprofen if I test positive for Dengue?
Medications like aspirin, ibuprofen, and naproxen thin your blood and can irritate your stomach lining. Because dengue already lowers your platelet count and increases bleeding risks, taking these medications can trigger dangerous internal bleeding. Use paracetamol strictly for fever management as advised by your doctor.
Why is the Immunochromatography method preferred for initial screening?
It is a rapid, globally trusted testing platform that provides clear, easy-to-read results within hours, making it an essential tool for quick clinical decisions in emergency rooms and clinics.
Can children take this rapid test safely?
Yes, absolutely. Children are highly vulnerable to fluid shifts from dengue. We use specialized pediatric collection methods to ensure a fast, safe, and comfortable blood draw.
How long do IgM antibodies stay positive after I recover?
Dengue-specific IgM antibodies typically stay clear and measurable in your blood for roughly 2 to 3 months after you have completely recovered from the fever before fading away.
How can I securely download my final digital report?
Once authorized and signed by our senior laboratory pathologists, your verified digital PDF report can be downloaded instantly from www.drpatholab.in using your registered details.
Are my infectious disease screening records kept private?
Absolutely. We enforce strict medical confidentiality guidelines and fully encrypted digital pipelines across our entire network infrastructure to ensure your diagnostic profile remains completely private.
